AI Article Synopsis
- Hydrocephalus is a rare presentation of neurosarcoidosis, with only five documented cases appearing as the initial symptom.
- A 31-year-old man with no significant medical history was diagnosed after exhibiting mild symptoms and imaging revealing significant brain enlargement and inflammation.
- Post-surgery, biopsies confirmed the diagnosis of sarcoidosis, leading to effective treatment with corticosteroids.
Article Abstract
Introduction: Hydrocephalus is very uncommon in neurosarcoidosis. To date, there have been only five reported cases of hydrocephalus occurring as the first manifestation of neurosarcoidosis. Such a presentation in a previously healthy patient is challenging to diagnose.
Case Presentation: A 31-year-old Japanese man who had no relevant past history other than sinusitis was admitted to our institution complaining of low-grade fever and mild headache. He was alert and neurologically intact. No respiratory symptoms were observed. Laboratory examination revealed mild elevation of erythrocyte sedimentation rate and serum CD4/CD8 ratio. Serum angiotensin-converting enzyme level was in the normal range. His cerebrospinal fluid showed mild pleocytosis and increased protein level. A chest X-ray revealed bihilar lymphadenopathy with normal lung parenchyma. Computed tomography of his head showed remarkable hydrocephalus with dilatation of all ventricles, particularly the fourth. Gadolinium-enhanced magnetic resonance imaging demonstrated leptomeningeal millet seed-like enhancement and multiple small enhancing lesions along the Virchow-Robin spaces. These findings strongly suggested a chronic inflammatory disease such as neurosarcoidosis. To treat the hydrocephalus, a ventriculoperitoneal shunt was inserted. The postoperative course was satisfactory. After surgery, nasal and skin biopsies were performed and pathological analysis revealed non-caseating granulomas consistent with sarcoidosis. The findings of gallium scintigraphy also supported the diagnosis of sarcoidosis. We obtained the definitive diagnosis of sarcoidosis 3 weeks after admission from the pathological findings by the nasal and skin biopsies, and corticosteroid therapy was started after that.
Conclusion: We present a rare case of neurosarcoidosis manifesting as acute hydrocephalus with dilatation of all ventricles, particularly the fourth. As hydrocephalus due to neurosarcoidosis has high morbidity and mortality, early diagnosis and proper treatment are particularly important.

Background: There has been significant progress in understanding neurosarcoidosis (NS) as a distinct disorder, which encompasses a heterogeneous group of clinical and radiological alterations which can affect patients with systemic sarcoidosis or manifest isolated.
Rationale And Aim Of The Study: The healthcare challenges posed by NS and sarcoidosis in general extend beyond their physical symptoms and can include a variety of psychosocial factors, therefore the recognition of main neuropsychiatric symptoms can be useful to approach patients with NS. Methods: For this purpose, databases such as Pubmed, Medline and Pubmed Central (PMC) have been searched.

Spinal cord sarcoidosis, an uncommon manifestation of neurosarcoidosis, presents diagnostic and therapeutic challenges because the condition is rare and has diverse clinical manifestations that can mimic other conditions such as multiple sclerosis and neuromyelitis optica spectrum disorder. A middle-aged African American female with a history of idiopathic intracranial hypertension and hydrocephalus with ventriculoperitoneal shunt presented with progressive, predominantly left-sided gait instability, weakness, and paresthesia. Cerebrospinal fluid showed lymphocytosis, red blood cells, elevated oligoclonal bands, and elevated kappa free light chains, concerning for multiple sclerosis.

While it commonly affects the lungs and the reticuloendothelial system, it can affect any organ. Most of such cases involve the central nervous system, but the condition rarely presents with symptoms related to hypothalamic-pituitary dysfunction.

Most often presenting with cranial neuropathies, basilar meningitis or pituitary/hypothalamic dysfunction, isolated involvement of the spinal cord without cranial manifestations is exceptionally rare, often involving intramedullary lesions. Here, we present the unique case of a 64-year-old female with atypical neurosarcoidosis presenting with myelopathy from extra-dural nodules without other neurologic or systemic symptoms.

Article Synopsis
- * Diagnosing sarcoidosis is challenging due to its diverse presentations and the absence of specific biomarkers, leading to complications in understanding its course and treatment.
- * The review emphasizes the need for new diagnostic criteria and recommends developing a reliable immunological or imaging marker to improve diagnosis and prognosis for patients with chronic sarcoidosis.
