Cerebral Aspergillosis Mimicking a Neoplasm in an Immunocompetent Patient.

Cerebral aspergillosis mostly presents as single or multiple abscesses with vascular invasion in immunocompromised patients. A rare mass like or tumoral form of cerebral aspergillosis has been described mostly in immunocompetent patients. A 22-year-old-male presented with recurrent attacks of complex partial seizures with secondary generalization, headache, and blurring of vision. Preoperative diagnosis of a cerebral neoplasm was considered in view of solid mass-like enhancement. However, histopathological examination was suggestive of central nervous system aspergillosis. The presence of imaging findings such as T2 hypointensity, irregular frond-like margins, and absence of choline peak may be the clues, which suggest a fungal etiology.
