Abstract
OBJECTIVE To determine the characteristic clinical and spinal MRI phenotypes of sarcoidosis-associated myelopathy (SAM), we analyzed a large cohort of patients with this disorder. METHODS Patients diagnosed with SAM at a single center between 2000 and 2018 who met the established criteria for definite and probable neurosarcoidosis were included in a retrospective analysis to identify clinical profiles, CSF characteristics, and MRI lesion morphology. RESULTS Of 62 included patients, 33 (53%) were male, and 30 (48%) were African American. SAM was the first clinical presentation of sarcoidosis in 49 patients (79%). Temporal profile of symptom evolution was chronic in 81%, with sensory symptoms most frequently reported (87%). CSF studies showed pleocytosis in 79% and CSF-restricted oligoclonal bands in 23% of samples tested. Four discrete patterns of lesion morphology were identified on spine MRI: longitudinally extensive myelitis (n = 28, 45%), short tumefactive myelitis (n = 14, 23%), spinal meningitis/meningoradiculitis (n = 14, 23%), and anterior myelitis associated with areas of disc degeneration (n = 6, 10%). Postgadolinium enhancement was seen in all but 1 patient during the acute phase. The most frequent enhancement pattern was dorsal subpial enhancement (n = 40), followed by meningeal/radicular enhancement (n = 23) and ventral subpial enhancement (n = 12). In 26 cases (42%), enhancement occurred at locations with coexisting structural changes (e.g., spondylosis). CONCLUSIONS Recognition of the clinical features (chronically evolving myelopathy) and distinct MRI phenotypes (with enhancement in a subpial and/or meningeal pattern) seen in SAM can aid diagnosis of this disorder. Enhancement patterns suggest that SAM may have a predilection for areas of the spinal cord susceptible to mechanical stress.

Abstract
OBJECTIVES Neurosarcoidosis (NS) and primary angiitis of central nervous system (PACNS) are inflammatory diseases affecting central nervous system, with overlapping clinical and pathological characteristics. Distinguishing these diseases is important given distinct therapeutic implications. In this study, we aimed to compare demographic, CSF and MRI characteristics between these two conditions. METHODS All the clinical, CSF and laboratory characteristics at the time of presentation were retrieved from electronic medical records. Brain and/or spinal cord MRI performed near the time of presentation were blindly evaluated by two neuroradiologists. Data regarding involvement of pachy- and leptomeninges, basal meninges, cranial nerves, cerebral grey and white matter, and spinal cord were recorded for each patient. RESULTS 78 patients with PACNS and 25 patients with NS were included in the study. Mean age of patients was 43.7 (±16.7) and 43.6 (±12.5) in PACNS and NS, respectively. African-American race was found to be associated with the diagnosis of NS rather than PACNS. Patients with PACNS had higher frequency of cerebral involvement, while patients with NS demonstrated more frequent spinal cord, basal meningeal and cranial nerve involvements. CONCLUSIONS These findings suggest that MRI can be an efficient tool in distinguishing PACNS from NS. A follow-up study with a larger sample size would be required to validate our results.

Abstract
Sarcoidosis (SA) is a granulomatous, multisystem disease of unknown etiology. Most often the disease affects lungs and mediastinal lymph nodes, but it may occur in other organs. Neurosarcoidosis (NS) more commonly occurs with other sarcoidosis forms, in 1% of cases it involves only nervous system. Symptomatic NS occurs but on autopsy study up to 25% of cases are confirmed. NS can affect central nervous system: the brain, spinal cord and peripheral nerves, and muscles. The diagnosis of neurosarcoidosis facilitates diagnostic criteria: histopathological, imaging and cerebrospinal fluid examination, and clinical symptoms. At present, there are no set standards for treatment of patients suffering from NS. Early therapy of symptomatic patients is recommended. Corticosteroids still are the first line of treatment for NS patients. In cases of steroids resistance, lack of their effectiveness or existence of contraindication to their use, immunosuppressant treatment is recommended. The latest NS algorithm with immunosuppressive treatment is discussed.

Abstract
INTRODUCTION Neurosarcoidosis occurs in about 5% to 15% of patients with sarcoidosis. The purpose of this study was to identify and characterize a cohort of neurosarcoidosis patients and to review the largest previously reported neurosarcoidosis case series. METHODS This retrospective study enrolled all patients with the diagnosis of probable or definitive neurosarcoidosis according to Zajicek and Scolding criteria, followed at the neurology department of a tertiary center in Portugal from January 1989 to December 2015. RESULTS A total of 15 patients presented a diagnosis of probable or definitive neurosarcoidosis, with a mean age at time of diagnosis of 38.5years. The presenting neurologic syndrome was isolated cranial neuropathy, aseptic meningitis, myelitis, brain parenchymal lesion, myelorradiculitis and meningomyelorradiculitis. MRI study most often presented different enhancing lesions and the CSF analysis commonly revealed a lymphocytic pleocytosis and raised proteins. Thirteen patients had histopathology confirmation of systemic sarcoidosis and one preformed a spinal cord biopsy. Corticosteroids was the most often used treatment alone or in combination with immunosuppressive drugs. After a mean follow-up of 86.1months, the majority of patients fully recovered to a mRankin 0. DISCUSSION Fully comprehension of neurosarcoidosis is still a challenge due to its rarity and limited number of large published series, which renders the epidemiological study of this disease very difficult. In this study, the thoroughly medical records review and the summarize of previous published cohorts allow to add some information in the epidemiological and clinical knowledge of this entity.

Abstract
We describe a patient with a history of longstanding primary generalised epilepsy, on anticonvulsant therapy, who presented with fever, headache, worsening seizures and hallucinations. Among various investigations, the patient had high CSF protein and ACE levels, leptomeningeal nodular enhancement on MRI brain and non-caseating granulomas in the brain and meninges on the biopsy. The patient was diagnosed with neurosarcoidosis. Subsequently, he was found to be panhypogammaglobulinaemic and was diagnosed with probable common variable immunodeficiency (CVID). The coexistence of common variable immunodeficiency and neurosarcoidosis is rare. Typically, non-caseating granulomas in CVID patients are localised in the lymphatic tissue and solid organs. To our knowledge, there are only five reports of the granulomas of the central nervous system (CNS) in CVID. We discuss the diagnostic difficulties in this case and review the literature.

Abstract
Neurosarcoidosis is often a diagnostic dilemma, especially in the absence of other organ involvement. We report a 64-year-old patient who had suffered from paraplegia due to an intramedullar process since 1995. The presumptive diagnosis based on computed tomography was spinal cord infarction. Six years later, he complained about increasing paresthesia. Magnetic resonance imaging of the spinal cord showed nodular meningeal enhancement. Computed tomography of the thorax revealed mediastinal and hilar lymphadenopathy. Bronchoscopy under generalized anesthesia was performed. The differential cell count in bronchoalveolar lavage fluid showed 39% lymphocytes and a CD4(+)/CD8(+) ratio of 17.7. Histological examination of biopsy specimens from the hilar lymph nodes revealed non-necrotizing granulomas with epitheloid cells and Langerhans-type giant cells, consistent with the diagnosis of sarcoidosis. As a result of these findings, lumbar puncture was undertaken and a raised protein concentration and pleocytosis were found in the cerebrospinal fluid. The number of lymphocytes (9,250 lymphocytes/l) and a CD4(+)/CD8(+) ratio of 10.78 led to the diagnosis of neurosarcoidosis. Paralysis might have been prevented if the correct diagnosis of neurosarcoidosis had been established earlier in this patient.

Abstract
INTRODUCTION HIV infection is the main cause of cryptococcal neuromeningitis but other diseases may be associated with this infection. CASE REPORT We report a case of cryptococcal neuromeningitis in a patient with sarcoidosis and ventriculoatrial shunting. The patient was successfully treated by effective therapy without device withdrawal. CONCLUSION The relationship between cryptococcosis and sarcoïdosis has been already described and may be not fortuitous. However it remains a very rare complication of sarcoidosis. Because of its potential severity (mortality rate of 40%), the diagnosis of cryptococcosis should be evoked as a differential diagnosis of neuro-sarcoidosis.

Abstract
OBJECTIVE Chronic involvement of the nervous system is relatively rare in sarcoidosis. We describe 7 cases that fulfil Zajicek's criteria for neurosarcoidosis (NS) and propose some modifications to such criteria. MATERIALS AND METHODS The patients were admitted for various neurological syndromes: 2 cases presented with chronic lymphocytic meningitis, 4 with spinal cord symptoms, one case was initially confused with multiple sclerosis. Serological tests, immunological screening, cerebrospinal fluid (CSF) analysis, bacteriological and viral testing were performed in all patients. Spinal and cerebral MRI, gallium scan, bronchoscopy with biopsy and bronchoalveolar-lavage fluid analysis, high-resolution computed tomography (HRCT) of the chest, biopsy of the lungs, skin, mediastinal lymph-node and meninges, were useful in diagnosing NS. RESULTS AND DISCUSSION Laboratory tests showed serum inflammatory abnormalities, but were negative for infectious diseases, while CSF showed inflammatory signs in all patients. MRI revealed meningeal enhancement or hypertrophic pachymeningeal lesions in 4 patients, white matter abnormalities and mass lesions in 2 patients, and a spinal mass lesion in 1 patient. Gallium scan, HRCT, bronchoscopy were positive in most cases. Patients were treated with steroid and immunosuppressive therapy, with improvement in six cases. One patient died from infectious complications. CONCLUSION A definite diagnosis of NS requires demonstration of non-caseating granulomas affecting nervous tissues. In most cases, histological evidence of systemic disease (probable NS) is sufficient in the presence of compatible alterations in the CNS. In our patients the bronchoalveolarlavage fluid analysis, gallium scan, and chest HRCT were important for diagnosis, while serum ACE was always normal and chest radiographs were not suggestive of sarcoidosis.

Abstract
Sarcoidosis is a disease of unknown aetiology. This granulomatous disease is essentially localized in lung and skin, but many other localizations are possible, such as in nervous system. Sometimes the neurological involvement is alone leading to a differential diagnosis from other neurological diseases. Angiotensin I-converting enzyme (ACE) is synthesized by sarcoidotic granulomas and diffuses in various biological fluids. The determination of ACE activity in cerebrospinal fluid (CSF) can help for the diagnosis of neurosarcoidosis, associated or not to its determination in serum. We developed a radiometric assay for the determination of ACE activity in CSF since the methods for serum cannot be used because ACE activity is low in CSF, as well as in pathological situations. At the analytical point of view this assay is sensitive, specific and reproducible. We established a normal range and yielded recommendations to give the results, particularly in function of the aspect of the CSF and the proteinorrachia. But increased level of ACE in CSF is not specific of neurosarcoidosis since elevations were also shown in meningitis. We can claim for the routine use of ACE assay in CSF for differential diagnosis by eliminating neurosarcoidosis, as well as for positive diagnosis of this disease, but in both cases with the confrontation to other parameters.

Abstract
BACKGROUND Neurosarcoidosis is a rare manifestation of sarcoidosis. Involvement of the nervous system in sarcoidosis can range from peripheral or cranial neuropathy to central nervous system disease. Cauda equina sarcoidosis is distinctly rare. REVIEW SUMMARY The authors present a 58-year-old patient with systemic sarcoidosis who developed cauda equina and conus medullaris syndrome. Seventeen previous published cases of cauda equina sarcoidosis are reviewed. The history of systemic sarcoidosis, cerebrospinal fluid characteristics of lymphocytic pleocytosis with elevated protein, and evidence of acute denervation by needle electromyography are helpful in the diagnosis of this condition. Early diagnosis and treatment of cauda equina sarcoidosis usually provide a rapid recovery and yield a good prognosis. CONCLUSION Although rare, sarcoidosis should be considered in the differential diagnosis of cauda equina syndrome, particularly in patients with unclear etiology.

Abstract
A number of neurological syndromes may be evoked by involvement of the nervous system due to systemic diseases such as lupus erythematosus, sarcoidosis, Behcet's disease, and Sjogren's syndrome. Because of different treatment strategies, it is important to distinguish between these different diseases. Neither clinical signs nor additional analyses such as serological findings or cerebrospinal fluid analysis are able to differentiate between the diseases with certainty. Nevertheless, diagnosis may finally be made taking all findings together. Here we compare typical clinical and cerebrospinal fluid findings in neurosarcoidosis, neurolupus, neuro-Behcet, and nervous system involving Sjogren's syndrome, with special emphasis on those findings allowing differentiation of the respective diseases.

Abstract
OBJECTIVE To describe a group of patients with neurosarcoidosis and to highlight diagnostic difficulties based on current diagnostic criteria. METHODS The patient database of a general neurological department was searched for patients with established or suspected diagnosis of neurosarcoidosis. Twenty-four patients were identified with definite (n = 3), probable (n = 10) and possible neurosarcoidosis (n = 10). History and clinical, laboratory and imaging data of patients with definite and probable neurosarcoidosis were analyzed. RESULTS Cranial nerve symptoms were a dominant clinical feature, with the optic nerve being affected most frequently. Cerebrospinal fluid pleocytosis was found in more than half of the patients. Intrathecal IgG synthesis and oligoclonal bands were less frequent. There was a wide array of MRI lesions in both groups. Chest X-ray was false negative in 2 of 5 patients who also underwent a thoracic CT. Therapy with prednisolone was initiated in all patients. After a median of 36 months, 6 of 8 patients with follow-up data of >24 months were still in remission. Aggravation of symptoms required therapy escalation in 2 patients. CONCLUSION There is a wide range of clinical symptoms and test results in patients with "definite" or "probable" neurosarcoidosis. Because systemic involvement is a crucial diagnostic criterion, extensive medical work-up may be necessary. Prognosis under corticosteroid treatment may be better than previously thought.

Abstract
Sarcoidosis is a multisystemic disease which involves the nervous system in 5 to 15 p.cent. Neurosarcoidosis without signs of systemic disease is rare and may be difficult to diagnose. We report a case of a 61 year-old patient with a pseudotumoral neurosarcoidosis and along evolution of 25 years without systemic signs. In such cases, histological analysis is rewarding.

Abstract
This report describes a patient with cryptococcal meningitis and newly diagnosed sarcoidosis not taking corticosteroids. Sarcoidosis is an independent risk factor for cryptococcal infection; most patients with sarcoidosis who develop cryptococcal infection are not on immunosuppressive drugs. Cryptococcal meningitis in sarcoid patients often presents clinically with non-specific features, and should be excluded in patients with sarcoidosis and neurological disturbances.

Abstract
OBJECTIVE To redefine the utility of CSF-ACE as a selective indicator of probable CNS neurosarcoidosis. METHODS The diagnosis of probable CNS neurosarcoidosis required: (a) biopsy evidence of systemic sarcoidosis, (b) cortical, brainstem, and/or spinal cord deficits, (c) enhancing lesions on brain and/or spinal cord MRI, and (d) exclusion of other etiologies which could account for the neurological deficits. Radioassay measurement of CSF-ACE activity was performed in 11 patients who met our criteria for probable CNS neurosarcoidosis and 207 control patients. RESULTS The M +/- SD for CSF-ACE activity was significantly higher (p < 0.05) for the 11 probable CNS neurosarcoidosis patients (9.5 +/- 6.9 nmol/mL/min) than for the control patients (2.9 +/- 2.7 nmol/mL/min). The optimal CSF-ACE activity discriminator value was 8 nmol/mL/min. At this value, the sensitivity and specificity of CSF-ACE activity was 55% and 94%, respectively. CONCLUSIONS CSF-ACE activity is a useful biochemical marker of probable CNS neurosarcoidosis when brain and/or spinal cord MRI show diffuse enhancing lesions.

Abstract
Neurosarcoidosis is a rare, but well-recognized cause of hypopituitarism with a predilection for the hypothalamus. We describe a case of panhypopituitarism in a 57-yr-old Asian lady, associated with an infiltrating hypothalamo-hypophyseal lesion, and other intracranial deposits, initially diagnosed as cerebral tuberculomata. Despite antituberculous therapy, the intracranial lesions progressed with significant clinical deterioration. Repeated lumbar puncture, magnetic resonance imaging scans, liver biopsy and Gallium scan were noncontributory, and the diagnosis of isolated neurosarcoidosis was established only following biopsy of an intracranial lesion. The lesion regressed on steroid and azathioprine therapy. Isolated neurosarcoidosis poses a considerable management problem. We review recent advances in the investigation, diagnosis, and treatment of this condition.

Abstract
A neurological localization is observed in 20% of the cases of sarcoidosis. Involvement of the central and/or peripheral nervous system is generally observed in Caucasians while cranial nerve localization predominates in blacks. Beside these particular elements, lymphocytic meningitis, psychiatric disorders, insipid diabetes, and cranial nerve palsy are the most frequent signs. A cerebrospinal fluid test as well as brain and spinal cord MRI with gadolinium injection is required in all cases. Depending on the clinical expression, complementary tests may include PEA, PEV and neuropsychic tests. Histological proof of sarcoidosis granuloma is required for diagnosis but may be difficult to obtain when neurological signs are not associated with another localization. Systemic treatment is indicated, based on steroids, sometimes associated with another immunosuppressive agent. After acute treatment, chronic therapy must be maintained for years, and sometimes for life.

Abstract
INTRODUCTION Sarcoidosis is a disease of unknown cause, characterized by the presence of non-caseating granulomas in many organs. Neurological involvement is rare and only occurs in 5-7% of the patients, usually during the first two years after onset of the disease. The neurological findings vary depending on the site of the lesions. The treatment of choice is with glucocorticoids for at least 6-12 months. Some patients in whom this treatment fails or leads to intolerable side-effects may respond well to immunosuppressive drugs and/or radiotherapy. CLINICAL CASE We present the case of a 31 year old man who complained of severe headache. He was referred to our department with the diagnosis of neurosarcoidosis and progressive neurological deterioration on conventional treatment. Holocranial radiotherapy with Co60 (30 Gy in 10 sessions) was given. Three months after this treatment had been given there was clinical improvement. CONCLUSIONS Radiotherapy may be an effective alternative when other treatment fails or glucocorticoids cause intolerable toxicity. The recommended dose is between 12 and 30 Gy, divided into 150-300 cgy/day.

Abstract
In a case of neurosarcoidosis with bilateral facial nerve palsy and hydrocephalus, contrast-enhanced magnetic resonance imaging (MRI) study and angiotensin converting enzyme (ACE) activities in cerebrospinal fluid (CSF) were valuable for the diagnosis and the follow up. Facial nerve lesions were demonstrated on gadolinium-DTPA enhanced MRI. The disappearance of enhancement was concomitant with the amelioration of facial nerve palsy after corticosteroid therapy.

Abstract
The etiology of sarcoidosis is unknown, but it has long been suspected to be mycobacterial. In the present study, we used 4 mycobacterial species-specific polymerase chain reaction assays on cerebrospinal fluid obtained from a patient with neurosarcoidosis. Positive hybridization was observed with both the Mycobacterium avium complex probe and the insertion element IS900-specific probe that has been found in M. paratuberculosis species. There was no hybridization with M. tuberculosis or M. avium woodpigeon strain-specific probes. This case report demonstrates that M. paratuberculosis or some closely related M. avium spp which perhaps also carry IS900, or contain closely related DNA sequences, are associated with at least some cases of sarcoidosis disease.

Abstract
Cell wall-defective bacteria which later reverted to acid-fast bacilli have been isolated from sarcoid tissue. These have not been conclusively shown to be mycobacteria. Specific PCR assays were applied to identify mycobacterial nucleic acids in these cultured isolates and in fresh specimens obtained from patients with sarcoidosis. Positive amplification and hybridization were observed with Mycobacterium avium complex- and/or Mycobacterium paratuberculosis-specific probes in five of the six cultured isolates and two fresh skin biopsy samples and one cerebrospinal fluid specimen. There was no amplification or hybridization with Mycobacterium tuberculosis or M. avium subsp. silvaticum probes, respectively. Patients' sera were also tested for antibody reactivities by immunoblotting with M. paratuberculosis recombinant clones expressing the 36,000-molecular-weight antigen (36K antigen) (p36) and the 65K heat shock protein (PTB65K). All seven sarcoidosis, four of six tuberculosis, and all six leprosy patient serum specimens showed strong reactivity with p36 antigen. In contrast, 13 of 38 controls showed only weak reactivity with p36 (P = 0.002 for controls versus sarcoidosis samples). Similarly, PTB65K reacted with high intensity with sera from 5 of 5 sarcoidosis, 5 of 6 tuberculosis, and 5 of 6 leprosy patients, compared with its low-intensity reaction with 5 of 22 controls (P = 0.001 for controls versus sarcoidosis samples). This study demonstrates the isolation and/or identification of M. paratuberculosis or a closely related M. avium complex strain from sarcoid skin lesions and cerebrospinal fluid. Furthermore, the reactivity of antibodies in sarcoid patient sera against p36 and PTB65K antigens was comparable to the reactivity of sera obtained from patients with known mycobacterial disease. Collectively, these data provide further support for the theory of the mycobacterial etiology of sarcoidosis.

Abstract
We described a young male with severe Guillain-Barré syndrome in whom pulmonary sarcoidosis was also detected. Based upon the results of diagnostic procedures (nerve biopsy, CSF examination, electrophysiological study) we postulate that this was a Guillain-Barré syndrome coexisting with sarcoidosis, and not the case of sarcoid neuropathy.

Abstract
A retrospective study of CSF and serum analysis from a total of 43 patients with sarcoidosis, 20 with systemic lupus erythematosus, and 12 with Behçet's disease with neurological involvement found local synthesis of oligoclonal IgG using isoelectric focusing and immunoblotting in 51%, 25%, and 8% respectively at some stage in their disease. Blood-brain barrier breakdown, when assessed with an albumin ratio found 47% of patients with sarcoidosis, 30% of those with systemic lupus erythematosus, and 42% of patients with Behçet's disease exhibiting abnormal barrier function at some time. Serial CSF analysis showed that clinical relapses were associated with worsening barrier function and in some patients the development of local oligoclonal IgG synthesis; conversely steroid treatment led to a statistically significant improvement in barrier function, and in two patients a loss of oligoclonal IgG bands. A higher proportion of patients had MRI abnormalities than oligoclonal IgG or blood-brain barrier breakdown, MRI being abnormal in 16 of 19 patients with sarcoidosis, three of four patients with systemic lupus erythematosus, and seven of nine patients with Behçet's disease, although this may have been due to temporal factors. In the differential diagnosis of chronic neurological disorders, locally synthesised oligoclonal IgG cannot distinguish between diseases, but the loss of bands seen in two patients contrasts with what is seen in multiple sclerosis, and thus may be a useful diagnostic clue.

Abstract
This study was aimed at investigating the value of MRI in the diagnosis of multiple sclerosis. In the Multiple Sclerosis Center of our University, we sorted out of the patients submitted to CSF and MR examinations, only those with clinically unquestionable multiple sclerosis, white matter abnormalities at MRI and normal CSF examination. These 21 patients were submitted to CSF and MRI examinations which were repeated whenever required if image quality was technically suboptimal; a variety of screening tests for different diseases mimicking multiple sclerosis were also performed. In 4 patients with white matter abnormalities at MRI which were considered atypical for multiple sclerosis, at image rereading and after laboratory tests the diagnosis were: coagulopathy, sarcoidosis, vasculitis and CNS lymphoma. In 2 cases with questionable white matter abnormalities at MRI, the final diagnosis were borreliosis and vasculitis. The remaining 15 patients had a diagnosis of multiple sclerosis in all but 3 cases in which subsequent clinical and laboratory examinations demonstrated the presence of vasculitis, embolism from interatrial septal aneurysm and mitochondrial disease. Our study suggests that in the patients with clinical findings of multiple sclerosis and disseminated MR lesions mimicking multiple sclerosis, but no CSF abnormalities, the classical clinical criteria may not be sufficiently specific and other diagnoses must therefore be excluded before making an "unquestionable" diagnosis of multiple sclerosis.

Abstract
The intrathecal synthesis of interleukin 10 (IL-10) was investigated in 120 paired cerebrospinal fluid (CSF) and serum specimens from patients with various inflammatory and non-inflammatory diseases of the central nervous system (CNS). IL-10 was not demonstrated in the sera, but detectable levels were found in the CSF from: patients with acute viral ("aseptic") meningitis, but only within 48-72 h of symptom onset; human immunodeficiency virus type 1 (HIV)-infected patients with HIV-related encephalitis/leukoencephalopathy or cryptococcal meningitis; a patient with primary B cell lymphoma of the CNS, and a patient with encephalomeningeal sarcoidosis (in whom IL-10 was demonstrated in all CSF collected over a period of 6-months). In chronic meningeal infections/inflammations, IL-10 seems to be continuously produced within the CSF. Our findings suggest that IL-10, a cytokine which exerts many immunosuppressive actions, may play different immunomodulatory roles in CNS diseases; in particular, its intrathecal synthesis may explain why some infectious and inflammatory meningeal diseases may have slow development and chronic evolution.

Abstract
We present two patients with known sarcoidosis who developed neurosarcoidosis manifested by paranoid psychosis and clinical diabetes insipidus with hypernatremia. Both had gadolinium enhanced magnetic resonance imaging which demonstrated leptomeningeal and hypothalamic enhancement. Both had elevated protein and a lymphocytosis in their cerebrospinal fluid, which improved after corticosteroid therapy. The patients improved clinically with this therapy as well. We suggest that new onset psychosis in a sarcoid patient, particularly with symptoms of hypothalamic/pituitary involvement, should be evaluated for neurosarcoidosis with an MRI and CSF examination. If the results are consistent with neurosarcoidosis, the patient should be treated promptly with corticosteroids.

Abstract
Neurosarcoidosis without systemic involvement is rare and difficult to diagnose. The case of a 27-year-old man with a 6-week history of headache, mental status changes, and polyradiculopathy attributable to hypoglycorrheic lymphocytic meningitis is presented. Extensive testing for occult systemic sarcoidosis was negative. The presence of noncaseating granulomatous inflammation was established by open brain biopsy, and the patient improved clinically with oral steroid therapy. In individuals with undiagnosed chronic meningitis, brain biopsy may be necessary to rule out isolated neurosarcoidosis.

Abstract
A 35-year-old man presented with the clinical picture of spontaneous subarachnoid hemorrhage. Four weeks after the first symptoms he noticed blurred vision, and ophthalmological examination detected bitemporal hemianopia. At this time cerebral computed tomography and magnetic resonance imaging showed enlargement of the optic chiasm, and visual evoked potentials revealed delayed latencies. In the cerebrospinal fluid cells and protein content were elevated, and angiotensin-converting enzyme was detectable. Under steroid treatment the patient recovered completely and computed tomography, magnetic resonance imaging, visual evoked potentials, and cerebrospinal fluid findings became normal. Although a great variety of neurological symptoms may occur in neurosarcoidosis, to our knowledge spontaneous subarachnoid hemorrhage as the presenting feature has never been reported before.

Abstract
Serial studies were done on cerebrospinal fluid (CSF) from a patient with sarcoidosis involving the meninges. Initially when the disease was active, the CSF protein was increased and glucose decreased. The number of cells in the CSF was moderately increased, and many mononuclear cells were present. Cytologic studies of the CSF showed many normal and some atypical lymphocytes. Immunochemical studies showed that most of these lymphocytes were T cells, with T-helper cells predominating over T-suppressor cells by a ratio of 3.92; B-lymphocytes were polyclonal. Subsequent studies of the CSF over the following three and one-half years showed that the protein and glucose content and the cell counts in the fluid did not correlate well with the activity of the disease. The number of atypical lymphocytes seemed to be a more useful marker of disease activity in the patient. Cytologic studies, when interpreted within the context of other CSF and clinical findings, are useful for the assessment of patients with sarcoidosis involving the meninges.

Abstract
Total neopterin (T-N), a by-product in the biopterin biosynthesis and an indicator of activation of the cellular immune system, and total biopterin (T-B) levels in cerebrospinal fluid (CSF), were measured in patients with various inflammatory neurological diseases and Parkinson's disease, and the following results were obtained. (1) In patients with neuro-sarcoidosis, neuro-Behçet's disease and meningitis, CSF T-N levels were markedly elevated in the exacerbation or acute stages of their neurological symptoms and remarkably decreased in the remission or chronic stages. In the neuro-sarcoidosis and neuro-Behçet's disease patients, however, CSF T-B levels showed no substantial change. (2) There was a significant positive correlation between CSF T-N levels and CSF/serum albumin ratios only in the meningitis patients. However, increases of CSF T-N levels were not associated with those of plasma T-N levels. (3) In the Parkinson's disease patients, CSF T-N levels remained normal, although CSF T-B levels significantly decreased. (4) A gradient for the CSF T-N value (lumbar greater than ventricular CSF), being reverse to the CSF T-B value, was observed. These results indicate that the significance of CSF T-N is quite different from CSF T-B, and that CSF T-N appears to be a valuable biochemical marker for evaluating the activity of inflammation within the central nervous system. Its measurement seems useful for therapeutic monitoring, especially of patients showing the chronic exacerbating-remitting course.

Abstract
Cerebrospinal fluid angiotensin converting enzyme (CSF-ACE) level was measured in two patients considered to have neurosarcoidosis, three patients with possible neurosarcoidosis and in 38 control patients suffering from prolapsed intervertebral discs. Both neurosarcoidosis patients had elevated levels (1.8 and 5.4 mumol/l/min) while the possible neurosarcoidosis patients had values similar to the control patients (mean 0.59 +/- 0.42 mumol/l/min). We suggest that CSF-ACE values may be of use in some patients as a diagnostic test for neurosarcoidosis and provide a reference range of normal controls.

Because no one laboratory test is diagnostic of multiple sclerosis, evaluation involves careful exclusion of other possible diagnoses. Magnetic resonance imaging is a valuable tool in this process. Clues from a scan can confirm findings from the history and physical and laboratory examinations. Dr Scott compares typical findings of multiple sclerosis with those of the four diseases that are sometimes mistaken for this syndrome.

Abstract
Neurosarcoidosis is a well-recognised complication of systemic sarcoidosis but diagnosis may be difficult if there is no clear evidence of an extracerebral manifestation of the disease. We present the case of a 42-year-old woman with clinical features characteristic of cerebral sarcoidosis including tetraparesis, diabetes insipidus, diencephalic hyperphagia, personality changes, and memory loss. Diagnosis was supported by cerebrospinal fluid (CSF) findings and magnetic resonance imaging (MRI): CSF showed mild lymphocytic pleocytosis, intrathecal production of IgG without oligoclonal bands, and a raised level of lysozyme. MRI revealed multiple contrast-enhanced granulomas at the base of the brain with partial involvement of diencephalic and mesencephalic structures and parts of the spinal cord. There was no evidence of systemic manifestation of sarcoidosis. Administration of corticosteroids led to improvement of the symptoms.

Abstract
The technique of antigen immunoblotting for detection of specific immunoglobulin G (IgG), using Kveim material as antigen, was applied to paired sera and cerebrospinal fluid from 11 patients with definite neurosarcoidosis, 9 patients with definite sarcoidosis and suspected neurosarcoidosis, 22 patients with possible neurosarcoidosis and 16 patients with other neurological disorders, including multiple sclerosis and optic neuritis. Six of the 11 (55%) patients with neurosarcoidosis, none of the 9 patients with definite sarcoidosis and suspected neurosarcoidosis, 5 of the 22 (23%) with possible neurosarcoidosis, and none of the control patients had local synthesis of specific IgG reacting with Kveim material at some stage in the disease. Six of the 8 (75%) patients with definite neurosarcoidosis who had never received steroids or immunosuppressants had local synthesis of Kveim-specific IgG. Local synthesis of Kveim-specific IgG was not found in patients who had received in the past, or were still receiving, immunomodulating agents, and local synthesis was abolished when such treatment was introduced to those patients who had been positive. Those patients whose cerebrospinal fluid showed local synthesis of oligoclonal total IgG were more likely to have local synthesis of Kveim-specific IgG, but not necessarily in an oligoclonal fashion. Immunoblotting, using Kveim material, may thus be a useful adjunct for the investigation of suspected neurosarcoidosis.

Abstract
Reports have suggested that the pattern of CSF IgG differentiates neurosarcoidosis from multiple sclerosis. We examined CSF and serum of 7 patients with neurosarcoidosis to determine concentrations of IgG and albumin and the presence of oligoclonal bands. Our results showed that neurosarcoidosis may have associated abnormalities of IgG synthesis and oligoclonal bands present in CSF, but without a consistent pattern.

Abstract
A retrospective chart review of neurosarcoidosis at the University of Texas Medical Branch (Galveston) between 1982 and 1987 revealed 99 patients with sarcoidosis. Six patients were diagnosed with neurosarcoidosis and had electrophoresis of serum and cerebrospinal fluid performed (one patient with a ventriculoperitoneal shunt was later excluded). Cerebrospinal fluid immunoglobulins and albumin levels were determined followed by calculation of an IgG index and synthesis rate for each patient. Four (80%) of five patients had elevated IgG indexes and synthesis rates indicative of intrathecal immunoglobulin production. No patient had immunoglobulin oligoclonal bands detected. To date, results of electrophoresis of cerebrospinal fluid in neurosarcoidosis have been reported in 37 patients among four series. Of these, only nine patients (24%) have had either an elevated IgG index or synthesis rate. Our series suggests that intrathecal immunoglobulin production in neurosarcoidosis occurs more frequently than previously described. Furthermore, the elevated indexes and synthesis rates without associated oligoclonal bands suggests a polyclonal immunoglobulin response.

Abstract
CSF lymphocyte subpopulations of eight patients with neurosarcoidosis were examined. CSF or CT was abnormal in all. The CSF T4/T8 (helper/suppressor) ratio was elevated at 6.8 and 7.6 in two patients; in one, there were only CSF T4 cells. The ratio was normal in five patients.

Abstract
Fifty consecutive patients with neurosarcoidosis were evaluated retrospectively. Sarcoidosis presented first with neurologic signs in 24 patients (48%), but systemic symptoms developed later in all but five. Main neurologic involvements were central nervous system lesions in 33 patients (66%), cranial nerve paresis in 12 (24%), and peripheral nerve lesions in five patients (10%). Seventeen patients (34%) had more than one type of neurologic involvement. Routine cerebrospinal fluid (CSF) parameters showed unspecific abnormalities in 35 patients (70%). CSF angiotensin converting enzyme was elevated in 18 of 31 patients (58%). Brain computerized tomography was abnormal in 13 of 32 patients (41%). Visual and brainstem evoked potentials were abnormal in ten (43%) and eight (35%) of 23 patients, respectively, suggesting subclinical lesions in 13 patients. Neurologic signs improved in 24 patients (48%), were stable in 11 (22%), and progressed in 15 patients (30%). Six patients died. Cranial nerve lesions improved most often. Course of neurologic involvements was similar in acute or subacute and chronic sarcoidosis. The effect of steroid treatment was inconsistent.

Abstract
The levels of lysozyme (LZM) and beta 2-microglobulin (beta 2m) were measured in the cerebrospinal fluid (CSF) and serum of 32 patients with sarcoidosis, 20 of whom had neurosarcoidosis. LZM was analyzed by a new radioimmunoassay (RIA) modification. CSF LZM was elevated in 15 of 20 patients with neurosarcoidosis but in only 4 of 12 patients with extraneural sarcoidosis. CSF beta 2m values were elevated in 13 of 19 and in one of 11 patients, respectively. In neurosarcoidosis, both CSF LZM and beta 2m correlated to CSF leucocytes but not significantly to CSF albumin thus suggesting that LZM and beta 2m were secreted from cells within the central nervous system (CNS). In patients with sarcoidosis, elevations of CSF LZM and beta 2m revealed disease activity in the CNS. Both analyses were also useful in the follow-up of neurosarcoidosis.

Abstract
Neurosarcoidosis is a disorder that is difficult to diagnose and manage. We assessed its neurological manifestations in 649 patients seen at The Johns Hopkins Hospital, Baltimore, from 1975 through 1980. Neurological problems could be attributed to neurosarcoidosis in 33 patients (5.1%). The presenting manifestation of sarcoidosis was neurological in 16 (48%) of them. Cranial neuropathy was the most frequent problem, and a peripheral facial nerve palsy was the single most common abnormality. Other manifestations were aseptic meningitis, hydrocephalus, parenchymatous disease of the central nervous system, peripheral neuropathy, and myopathy. Three-quarters of the patients were treated with steroids. The outcome was good in 27 (82%) of 33 episodes of neurological dysfunction in 25 patients with a well-documented clinical course. A thorough investigation of patients with suspected neurosarcoidosis is recommended to establish the diagnosis, delineate the extent of disease, and guide therapy.

Abstract
Serum and CSF angiotensin converting enzyme (ACE) were measured by a new inhibitor binding assay in 32 patients with sarcoidosis, 49 with neurologic diseases, and 38 controls. In neurosarcoidosis, 11 of 20 patients had high levels of CSF ACE. In systemic sarcoidosis without neurologic abnormality, only 1 of 12 patients had elevated CSF ACE. The highest value was observed in a patient with widespread meningeal sarcoidosis. High values were also observed in patients with bacterial meningitis or malignant tumors of the CNS. Fluctuation in successive analyses correlated to clinical course of neurosarcoidosis. CSF ACE analysis seems useful in diagnosis and follow-up of neurosarcoidosis.
