Cerebral granulomatous angiitis with atypical features

Area of Science:

• Neurology
• Pathology
• Neurosurgery

Background:

• Cerebral granulomatous angiitis is a rare vasculitis affecting the central nervous system.
• It can present with symptoms that mimic primary brain tumors, leading to diagnostic challenges.

Observation:

• A patient presented with a left temporal lobe mass that appeared to be a glioma on initial imaging.
• Surgical intervention revealed the mass to be granulomatous angiitis, not a tumor.

Findings:

• Histological examination confirmed granulomatous vasculitis.
• The patient was treated with a short course of dexamethasone post-surgery.

Implications:

• This case underscores the importance of considering rare inflammatory conditions in the differential diagnosis of brain tumors.
• Understanding the clinical and morphological variations of granulomatous angiitis is vital for accurate diagnosis and effective management.
