Sarcoidosis with hydrocephalus: report of a case successfully treated with a ventriculo-peritoneal shunt and methylprednisolone pulse therapy

Systemic autoimmune diseases complicated with hydrocephalus: pathogenesis and management

Systemic autoimmune diseases (SAIDs) represent a group of syndromes involving at least two organ systems. Classical SAIDs include connective tissue diseases, vasculitis, and granulomatous diseases, many of which involve the nervous system and result in different neurological manifestations. Hydrocephalus can be a rare but lethal complication of various SAIDs, including systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), sarcoidosis, and primary vasculitis. However, the pathogenesis of SAIDs complicated with different types of hydrocephalus is varied and difficult to determine using the existing published data, and various manifestations and expressive forms of the conditions bring a substantial challenge to a timely clinical diagnosis and treatment. The commonly used medical management programs based on the etiology of hydrocephalus are anti-inflammatory or anti-infectious therapies, while surgical management such as ventriculoperitoneal shunts is effective most of the time. Further research should be directed toward improving our understanding of the pathogenesis of these conditions and determining the most effective method for treating this life-threatening condition.

Management of hydrocephalus associated with autoimmune diseases: a series of 19 cases

OBJECTIVES

To analyze the diagnosis and treatment of hydrocephalus associated with autoimmune diseases and to explore the possible mechanism of hydrocephalus in these patients.

METHODS

A retrospective case series study was conducted at Peking Union Medical College Hospital, Beijing, China. Files were retrieved from the hospital archives by screening records from Jan 1990 to Jan 2016. Medical records were screened for data regarding (1) the number of patients diagnosed with hydrocephalus associated with autoimmune diseases, (2) the clinical manifestation of hydrocephalus associated with autoimmune disease, and (3) the outcomes of these patients treated with medication or ventriculoperitoneal shunt (VPS).

RESULTS

A total of 19 of 19,643 hospitalized autoimmune diseases patients were found to have hydrocephalus. Seven of the 19 patients had systemic lupus erythematosus (SLE), 3 patients had Sjögren's syndrome, 2 patients had rheumatoid arthritis (RA), 1 patient had connective tissue disease, 1 patient had juvenile idiopathic arthritis (JIA), 1 patient had Guillain-Barre syndrome (GBS), 1 patient had systemic sclerosis, 1 patient had Crohn's disease, 1 patient had relapsing polychondritis (RPC), and 1 patient had autoinflammatory disease (AID). Of the 19 patients, 13 received medication treatment, and the most commonly used drugs were corticosteroids and mannitol. A total of 6 patients received both medication therapy and VPS treatment with a programable valve. After average follow-up lengths of 11 months for patients who received VPS and 8.2 for patients who received medical treatment, the clinical symptoms of patients treated by VPS or medication were improved (83% (5/6) vs. 15.4% (2/13), respectively), patients were in stable condition (17% (1/6) vs. 30.8% (4/13), respectively), and mortality decreased (0% vs. 53.8% (7/13), respectively).

CONCLUSIONS

VPS along with corticosteroids and immunosuppressants represents an effective treatment approach for patients who suffer from hydrocephalus associated with autoimmune diseases.

Hypothalamic-pituitary sarcoidosis with hypopituitarism. Long-term remission with methylprednisolone pulse therapy

A 29-year-old man presented with diplopia and decreased strength in the left arm. A magnetic resonance image (MRI) showed an extensive hypothalamic and pituitary gland mass, and hormonal studies showed partial hypopituitarism and mild hyperprolactinemia without diabetes insipidus. Biopsies of the hypothalamic lesion and of a mediastinal lymph node demonstrated noncaseating granulomas, and a Kveim-Siltzbach test was positive. He was successfully treated with a regimen of high-dose intravenous methylprednisolone pulse therapy for eight weeks along with a low dose of oral corticosteroids which was maintained indefinitely. An MRI obtained immediately after pulse therapy revealed a substantial reduction in the hypothalamic-pituitary mass, which was maintained in an MRI performed 3 years later. However, hormonal deficits persisted and indefinite hormonal substitutive therapy was required.

Cerebral herniation after lumbar puncture in sarcoid meningitis

A patient with chronic meningitis due to neurosarcoidosis became comatose within minutes of a lumbar puncture and died 24 h later. The diagnosis of neurosarcoidosis was made post mortem. Development of cerebral herniation may have been exacerbated by lumbar puncture. It was proposed that arachnoid villi dysfunction may have contributed to very high intracranial pressures in this patient, since post mortem examination revealed communication between the ventricles and outlet foramina of the fourth ventricle, and that herniation was in part due to an acute pressure differential caused by lumbar puncture.

Progression of hydrocephalus during corticosteroid therapy for neurosarcoidosis

We describe a patient with sarcoid meningitis and hydrocephalus who improved rapidly after initiation of oral prednisone therapy, but who later decompensated acutely and required an emergency ventriculoperitoneal shunt. Hydrocephalus associated with neurosarcoidosis may progress despite steroid treatment, even when symptoms have improved. If hydrocephalus associated with neurosarcoidosis is treated with corticosteroids and without a shunt procedure we suggest that the corticosteroids should be continued at high doses for a prolonged period.
