[Pseudotumor cerebri revealing sarcoidosis]

Area of Science:

• Neurology
• Immunology
• Radiology

Background:

• Sarcoidosis is a multisystem granulomatous disease of unknown cause.
• Cerebral sarcoidosis is an uncommon manifestation with diverse clinical presentations.
• It can present as a misleading intracranial mass or pseudotumor.

Observation:

• A young Tunisian adult presented with symptoms of intracranial hypertension.
• Radiological imaging revealed a pseudotumoral lesion within the brain.
• The patient's condition was investigated further to determine the underlying etiology.

Findings:

• The pseudotumoral lesion and intracranial hypertension were diagnosed as manifestations of systemic sarcoidosis.
• This case underscores the importance of considering sarcoidosis in the differential diagnosis of intracranial masses.
• Systemic sarcoidosis can present with neurological involvement mimicking other pathologies.

Implications:

• Early diagnosis of cerebral sarcoidosis is crucial for appropriate management and preventing neurological damage.
• Recognizing sarcoidosis as a cause of pseudotumoral lesions can guide diagnostic workups.
• This case contributes to the understanding of rare neurological presentations of sarcoidosis.
