Abstract
BACKGROUND Sarcoidosis is a chronic inflammatory granulomatous disease of unknown cause. Delays in diagnosis can result in disease progression and poorer outcomes for patients. Our aim was to review the current literature to determine the overall diagnostic delay of sarcoidosis, factors associated with diagnostic delay, and the experiences of people with sarcoidosis of diagnostic delay. METHODS Three databases (PubMed/Medline, Scopus, and ProQuest) and grey literature sources were searched. Random effects inverse variance meta-analysis was used to pool mean diagnostic delay in all types of sarcoidosis subgroup analysis. Diagnostic delay was defined as the time from reported onset of symptoms to diagnosis of sarcoidosis. RESULTS We identified 374 titles, of which 29 studies were included in the review, with an overall sample of 1531 (694 females, 837 males). The overall mean diagnostic delay in all types of sarcoidosis was 7.93 months (95% CI 1.21 to 14.64 months). Meta-aggregation of factors related to diagnostic delay in the included studies identified three categories: (1) the complex and rare features of sarcoidosis, (2) healthcare factors and (3) patient-centred factors. Meta-aggregation of outcomes reported in case studies revealed that the three most frequent outcomes associated with diagnostic delay were: (1) incorrect diagnosis, (2) incorrect treatment and (3) development of complications/disease progression. There was no significant difference in diagnostic delay between countries with gatekeeper health systems (where consumers are referred from a primary care clinician to specialist care) and countries with non-gatekeeper systems. No qualitative studies examining people's experiences of diagnostic delay were identified. CONCLUSION The mean diagnostic delay for sarcoidosis is almost 8 months, which has objective consequences for patient management. On the other hand, there is a paucity of evidence about the experience of diagnostic delay in sarcoidosis and factors related to this. Gaining an understanding of people's experiences while seeking a diagnosis of sarcoidosis is vital to gain insight into factors that may contribute to delays, and subsequently inform strategies, tools and training activities aimed at increasing clinician and public awareness about this rare condition.

Abstract
BACKGROUND Involvement of the central nervous system is registered in a relatively small number of patients with sarcoidosis. In this article we present two cases with various neurological symptoms that fulfill criteria for neurosarcoidosis (NS). In addition, we review the literature on NS with special attention to isolated cranial nerve involvement. METHODS AND RESULTS First patient: Neurological examination identified multiple cranial neuropathy, moderate right-sided hemiparesis, polyradiculoneuritis of the lower limbs and positive meningeal signs. Laboratory tests showed serum and cerebrospinal fluid (CSF) inflammatory abnormalities, with increased values of the angiotensin-converting enzyme (ACE). CSF analysis also showed presence of 9 oligoclonal IgG bands. Brain and spine magnetic resonance imaging (MRI) revealed diffuse meningopathy, and focal granulomatous lesion in the body of the L5 vertebra. Lung sarcoidosis was confirmed by additional diagnostic procedures. The patient was treated with Methylprednisolone and a tapering course of oral Prednisone, which reduced the pain in the back and legs and improved the strength of the right leg. However, the other neurological deficiencies remained. After confirming lung sarcoidosis, the patient received Methotrexate in addition to Prednisone but during the following 2 years the patient's condition progressively worsened and ended in death. Second patient: Neurological findings showed weakness of the right n. oculomotorius and the right n. trochlearis, as well as the right-side face weakness. We found raised level of the ACE in serum and CSF. Thorax high-definition computed tomography (HDCTT) showed ribbon-like domains of discrete changes in the pulmonary parenchyma. MRI of the brain showed multiple white matter lesions. This patient also received Methylprednisolone followed by Prednisone, and after two months, ocular motility normalized. CONCLUSION The diagnosis of NS is always a challenge. For this rerason definitive diagnosis requires the exclusion of other causes of neuropathy. Multiple cranial neuropathies should always arouse suspicion of NS.

Abstract
OBJECTIVE We retrospectively investigated spinal magnetic resonance imaging (MRI) manifestations at neurological onset in Japanese patients with spinal cord sarcoidosis. METHODS Between July 2000 and April 2012, we reviewed our database and recruited patients with spinal cord sarcoidosis. On spinal MRI performed at neurological onset, the following items were evaluated: the vertebral-segment distribution and length of intramedullay T2-elongated lesions, abnormal enhancement patterns and distributions and the concomitant presence of spondylosis and associated extraspinal lesions. If available, brain MRI scans were concomitantly assessed. RESULTS Nine patients were enrolled (four men and five women; median, 49 years). Reflecting Japanese epidemiological backgrounds, a predilection for occurrence was observed in young men and middle-aged women. Intramedullary T2-elongated lesions were present in eight patients, peaking at the C5 level, with a mean length of 3.7 ± 2.6 vertebral segments. Spondylosis coexisted in the middle-aged patients. Abnormal intramedullary enhancement with concomitantly involved the nerve roots was observed in six patients, comprised of two types reflecting the disease progression: linear- and/or nodular enhancement along the surface of the spinal cord and intramedullary enhancement consisting of patchy, broad-based enhancement adjacent to the cord surface. Five patients had associated extraspinal lesions, including lymphadenopathy in four patients and brain involvement in four patients. CONCLUSION Spinal cord sarcoidosis exhibits a predilection for young men and middle-aged women among Japanese individuals and is characterized by intramedullary T2-elongated lesions spreading more than three vertebral segments peaking at the C5 level, two types of abnormal intramedullary enhancement reflecting disease progression, frequent nerve root involvement and lymphadenopathy.

Abstract
OBJECTIVE Intramedullary spinal sarcoidosis is a difficult diagnosis to make because of its nonspecific clinical and imaging features and its imitation of other common spine disorders. We present a patient with intramedullary spinal sarcoidosis that mimicked spinal cord injury from a cervical disk herniation. METHODS Relevant information was extracted from the patient's medical and imaging records. A thorough literature review subsequently was performed. RESULTS A 59-year-old woman presented to our institution with several months of intermittent parathesias, pain, and subjective weakness in her right upper and lower extremities. Magnetic resonance imaging of the cervical spine demonstrated a large osteophyte-disk complex at C4-5 adjacent to a small area of intramedullary spinal cord enhancement. The patient underwent C4-5 anterior cervical diskectomy and fusion for the osteophyte-disk complex. She initially improved postoperatively but subsequently worsened after a few months. Because of more prominent spinal cord enhancement, a posterior laminectomy and biopsy of the enhancing lesion was performed. Intramedullary spinal sarcoidosis was diagnosed, and she was treated medically with steroids and immunosuppressive agents. CONCLUSION Spinal sarcoidosis can mimic more common disease processes, such as cervical spondylosis. It is an important consideration in the diagnosis of intramedullary or intradural lesions of the spinal cord because early medical treatment may improve the course of the disease process. Surgery should be limited to biopsy for diagnostic purposes.

Abstract
Sarcoidosis can involve the central nervous system in approximately 5-15% of cases. Any part of the nervous system can be involved, so presentation can be quite varied. Isolated disease of the spinal cord is even less common and reports are limited to single cases and small series. Although in the setting of systemic disease the diagnosis can be made with skin or lymph node biopsy, isolated disease of the spinal cord presents a diagnostic challenge. We present a case of isolated intramedullary neurosarcoidosis of the distal thoracic spinal cord presenting with posterior column dysfunction. Imaging demonstrated T2 changes in the patient's lower thoracic cord adjacent to disc herniation. Over time, however, his symptoms progressed despite decompression, and the abnormal region began to exhibit focal contrast enhancement. The persistence of symptoms as well as the new enhancement led us to perform a spinal cord biopsy, which demonstrated histopathological findings consistent with sarcoidosis. Further workup failed to reveal any evidence of systemic disease. Intramedullary sarcoidosis without systemic sarcoidosis is extremely rare. With its variable imaging appearance and inconsistent clinical manifestations, it can be difficult to diagnose. It should be considered in the differential diagnosis of a mass-like intramedullary lesion with progressive symptoms. Biopsy with histopathological correlation may be the only definite management option.

Abstract
STUDY DESIGN A retrospective multicenter study of series of 12 patients with spinal cord sarcoidosis who underwent surgery. OBJECTIVE To evaluate the postoperative outcomes of patients with cervical spinal cord sarcoidosis accompanied with compressive myelopathy and effect of decompressive surgery on the prognosis of sarcoidosis. SUMMARY OF BACKGROUND DATA Sarcoidosis is a chronic, multisystem noncaseating granulomatous disease. It is difficult to differentiate spinal cord sarcoidosis from cervical compressive myelopathy. There are no studies regarding the coexistence of compressive cervical myelopathy with cervical spinal cord sarcoidosis and the effect of decompressive surgery. METHODS Nagoya Spine Group database included 1560 cases with cervical myelopathy treated with cervical laminectomy or laminoplasty from 2001 to 2005. A total of 12 patients (0.08% of cervical myelopathy) were identified spinal cord sarcoidosis treated with decompressive surgery. As a control subject, 8 patients with spinal cord sarcoidosis without compressive lesion who underwent high-dose steroid therapy without surgery were recruited. RESULTS In the surgery group, enhancing lesions on magnetic resonance imaging (MRI) were mostly seen at C5-C6, coincident with the maximum compression level in all cases. Postoperative recovery rates in the surgery group at 1 week and 4 weeks were -7.4% and -1.1%, respectively. Only 5 cases had showed clinical improvement, and the condition of these 5 patients had worsened again at averaged 7.4 weeks after surgery. Postoperative oral steroid therapy was initiated at an average of 6.4 weeks and the average initial dose was 54.0 mg in the surgery group, while 51.3 mg in the nonsurgery group. The recovery rate of the Japanese Orthopedic Association score, which increased after steroid therapy, was better in the nonsurgery group (62.5%) than in the surgery group (18.6%) with significant difference (P < 0.01). CONCLUSION The effect of decompression for spinal cord sarcoidosis with compressive myelopathy was not evident. Early diagnosis for sarcoidosis from other organ and steroid therapy should be needed.

Abstract
INTRODUCTION Spinal neurosarcoidosis is rare and exceptionally inaugural. OBSERVATION A 49-year-old African woman developed a progressive left Brown-Sequard syndrome. Magnetic resonance imaging (MRI) scans of the cervical spinal cord revealed an intramedullary lesion from C2 to T1 with intense pial enhancement after administration of contrast material associated with cervical spondylosis. The diagnostic of sarcoidosis was confirmed by liver biopsy which demonstrated noncaseating granulomas. CONCLUSIONS MRI features of spinal neurosarcoidosis were reviewed by the authors with focus on differential diagnosis.

Abstract
Patients with neurosarcoidosis are usually initially treated with steroid administration even when they have concomitant cord compression on magnetic resonance imaging (MRI). Operative intervention may be indicated in patients with spinal cord sarcoidosis requiring either tissue biopsy for diagnosis or associated with progressive neurologic symptoms. However, there have been no previous reports describing clinical outcomes of laminoplasty for spinal cord sarcoidosis. The objectives of this study are to investigate whether extensive cervical laminoplasty is an effective treatment for spinal cord sarcoidosis combined with spondylotic changes and/or cervical spinal canal stenosis. Open-door laminoplasty was performed in three patients with spinal cord sarcoidosis. All patients received intensive corticosteroid therapy after the operation MRI imaging was performed in all patients before and after the operation. Operative outcomes were not satisfactory and the clinical courses of the patients fluctuated after corticosteroid therapy. Daily life activities were not significantly improved after treatments in any of the three patients, and in the long-term follow-up period the clinical course of one patient was one of inexorable deterioration to a state of quadriplegia. The possibility of spinal cord sarcoidosis should be included in the differential diagnosis, when a distinct high signal intensity area is observed within the spinal cord on T2-weighted MR images in patients with spondylotic changes. Laminoplasty is not an effective intervention for the treatment of spinal cord sarcoidosis even when patients have spondylotic changes and/or a constitutionally narrowing cervical spinal canal. Patients with neurosarcoidosis should be treated first with steroid administration even when they have concomitant cord compression on MRI.

Abstract
INTRODUCTION The spinal localization is rare for neurosarcoidosis (0.43 percent of cases) but can be the inaugural manifestation of the disease. We report two cases of spinal neurosarcoidosis in a 57-year-old man and a 43-year*old woman with uneventful past medical histories. Both presented progressive myelopathic features. METHODS Magnetic resonance imaging (MRI) of the spine demonstrated intramedullary lesions, dorsal in the first case, and cervical in the second case. Serum angiotensin converting enzyme was elevated. Radiographs of the chest revealed bilateral symmetric hilar mediastinal lymphadenopathy in the first patient, and bronchial biopsy demonstrated non caseating granulomas. In the second patient the diagnosis was made on pathological examination of a minor salivary gland biopsy. RESULTS The patients received corticosteroid therapy with good response in the second patient. CONCLUSION The diagnosis of intramedullary sarcoidosis is difficult without a previous diagnosis of systemic sarcoidosis or other apparent symptom(s). Extraneurologic biopsies may be suggestive. We reviewed the literature on the diagnosis and treatment of intramedullary sarcoidosis.

Abstract
INTRODUCTION Neurological involvement in sarcoidosis is rare and highly variable. To date, no consensus was reached about the diagnosis approach. We report a case series of 9 patients with neuosarcoidosis, with favorable outcome under therapy. MATERIALS AND METHODS We examined a case series of 9 patients with neurosarcoidosis. Clinical, radiological, therapeutic features and outcome were studied. RESULTS Six of the nine patients were females. Patients' age ranged from 31 to 70 years. Initial neurological symptoms lead to the diagnosis of systemic sarcoidosis in all patients. Central nervous system involvement was found in 77 percent with cranial nerve involvement in 55 percent. Twenty-three percent of patients presented with peripheral neuropathy and 33 percent with meningitis. The diagnosis was definite in 2 patients, probable in one and possible in six others. All patients were given steroid therapy. Total remission was obtained in three and partial remission in three. Three patients remained stable and one died. CONCLUSION Histological signs are not constant in neurosarcoidosis. The lack of these signs should lead the physician to search for latent extraneurological symptoms which are suggestive of the diagnosis. Nervous biopsy can thus be avoided.

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
Spinal neurosarcoidosis is rarely a presenting symptom. This case deals with a 45-year-old african woman who presented with a regressive spinal cord compression treated by parenteral corticosteroid. Different relapses allowed to diagnose multiple sclerosis. Spinal MRI scan showed diffuse enlargement of the cord with intense intramedullary enhancement from C3 to T1 and an aspect of large spinal cord from C7 to D1. Cranial MRI scan was normal. Radiographs and CT scan of the chest revealed an interstital syndrome without mediastinal lymphadenopathy (subgroup III). The serum angiotensin converting enzyme level was elevated in the blood as the cerebrospinal fluid. CSF fluid showed a lymphocytic meningitis. The bronchio-alveolar lavage found an hyperlymphocytosis with a high CD4/CD8 ratio. The neurological status and biological parameters were improved with oral corticotherapy treatment. This case report that a spinal cord involvement can reveal a sarcoidosis especially in the African race. Finally, in spite of lack of biopsy, the diagnosis is supported by clinical, biological and neuroradiological arguments.

Abstract
Neurosarcoidosis is a great mimicker. It is often difficult to diagnose particularly when there is no prior history of systemic sarcoidosis. Although certain sites of the neuraxis are more commonly involved than others, any site of the central or peripheral nervous system can be affected. We report a case of sarcoidosis involving the cauda equina in a 38-year-old African American male without prior history of systemic disease. Initial clinical presentation was suggestive of Guillian-Barré syndrome, but the evaluation proved this case to be neurosarcoidosis involving the cauda equina. We have followed this patient for 8 years, and he remains clinically stable on prednisone 5 mg/day.

Abstract
BACKGROUND CONTEXT Spinal sarcoidosis is rare. Most spinal sarcoid lesions are intramedullary, and only three cases of extramedullary sarcoid lesions have been reported. PURPOSE To describe a case of an extramedullary sarcoid lesion in a patient that did not have systemic involvement and to review the literature of spinal sarcoidosis. STUDY DESIGN/SETTING Case report and review of the literature. PATIENT SAMPLE Case report. OUTCOME MEASURES Report of resolution of symptoms. METHODS/DESCRIPTION The patient was a 33-year-old woman who had neck pain and pain radiating to the right scapula area and down the right arm into her hand and wrist. She also complained of numbness, tingling, muscle spasms and tremors, and had difficulty with writing. Magnetic resonance imaging showed a mass that was extramedullary in the right lateral aspect of the spinal canal at the level of C5 and extending into the right C5-6 neuroforamen. Admitting diagnosis of neurofibroma was made. The patient underwent C4, C5 and C6 laminoplasty and gross total resection of an intradural extramedullary tumor. The lesion encroached on the neuroforamen on the right side involving the C6 nerve root, was grossly adherent to some of the rootlets and looked like a Schwannoma. Gross total resection of the tumor was performed. Pathological examination of the specimen showed a noncaseating granulomatosis consistent with sarcoid. Postoperative testing did not reveal systemic involvement of sarcoidosis. The patient was treated with corticosteroids. RESULTS The patient made a satisfactory recovery, returned to work full-time, and had no complaints of neurological symptoms. CONCLUSIONS An extramedullary sarcoid lesion is rare. Unlike intramedullary sarcoid lesions, it can be totally removed. If no systemic sarcoidosis is present, the patient can have a satisfactory recovery.

Abstract
Sarcoidosis is a multisystemic disorder characterised by the presence of multiple noncaseating granulomas. Clinically recognisable nervous system involvement occurs in 5-16% of patients with sarcoidosis. However, the incidence of subclinical neurosarcoidosis may be higher. The following article presents a review of the disease, including its pathophysiology, clinical and radiological characteristics and treatment. Neurosarcoidosis should be included in the differential diagnosis of infectious and noninfectious neurological syndromes.

Abstract
Sarcoidosis is a chronic disorder of unknown etiology characterized by the development of non-caseating granulomas with derangement of the normal tissue architecture. Compromise of the spinal cord is one of the rarest neurologic manifestations of the disease, which may be clinically and radiologically indistinguishable from a spinal cord malignant tumor. However, neurosarcoidosis can be treated with steroids. This study reviews the clinical, radiological, and pathological features of the sarcoid compromise of the spinal cord, emphasizing the difficulties commonly encountered in making a diagnosis.

Abstract
BACKGROUND Intramedullary neurosarcoidosis may be the first manifestation of the disease and may mimic a tumor clinically and radiographically. Two patients who presented with cervical intramedullary lesions on magnetic resonance imaging (MRI) scans were found to have neurosarcoidosis. CLINICAL PRESENTATION Two patients with negative past medical history presented with progressive myelopathic features, and intramedullary cervical lesions were detected on MRI scan; the diagnosis was made on biopsy of the lesions. Early therapeutic intervention led to a favorable outcome. CONCLUSION Intra-medullary neurosarcoidosis, especially in the cervical cord, can be the initial presentation of the disease, mimicking a tumor. MRI scan, biopsy, and, in fewer cases, angiotensin-converting enzyme levels can help with the diagnosis and may lead to a favorable outcome.
