Summary
This case study highlights a rare instance of neurosarcoidosis affecting the dura mater in a young man. Prompt diagnosis via biopsy and subsequent steroid treatment led to the resolution of intracranial lesions.
Area of Science:
- Neurology
- Immunology
- Pathology
Background:
- Intracranial sarcoidosis, a manifestation of systemic sarcoidosis, can present with diverse neurological symptoms.
- Dural involvement is exceptionally rare, with only eight prior reported cases.
Observation:
- A 26-year-old male presented with altered consciousness, gait disturbance, and incontinence.
- Cerebrospinal fluid analysis revealed elevated pressure, cells, and protein.
- Head CT showed enlarged ventricles and enhancing nodular lesions on the falx cerebri.
Findings:
- Histopathological examination of biopsied dural lesions confirmed sarcoidosis.
- Elevated erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and gamma-glutamyl transpeptidase (GPT) were noted.
- Cerebrospinal fluid (CSF) analysis indicated inflammation with elevated protein and cell counts.
Implications:
- This case underscores the importance of considering sarcoidosis in the differential diagnosis of dural nodular lesions, alongside meningioma, lymphoma, and metastatic tumors.
- Biopsy confirmation is crucial for diagnosis in atypical presentations of neurosarcoidosis.
- Effective treatment with corticosteroid therapy led to complete resolution of the intracranial lesions.
