Abstract

|
Aspergillosis of the central nerve system is a rare disease, and intracranial fungal epidural abscess has not previously been described. We had been referred a 63-year old man who had 4 months history of hearing difficulty on his left ear and 3 months history of headache. Effusion of left middle ear was identified by otoscopy and tympanocentesis. Temporal bone CT showed soft tissue densities in middle ear, mastoid antrum and air cells with normal bony contours. T1 and T2-weigted MRI showed low signal intensity and peripheral rim enhancement after administration of gadolinium. Drainage of abscess through transmastoid approach was performed. Biopsy specimen showed septated fungal hyphae with Grocott’s methanamine silver (GMS) and Periodic acid-schiff (PAS) stains. The authors hereby report a case of aspergillus epidural abscess of the middle cranial fossa.
