Temporal lobe abscess as a complication of cholesteatoma: sequential radiological findings.

Temporal lobe abscess is a rare but known complication of petrosal bone cholesteatoma. We present a case with clinical history, diagnostic imaging and sequential radiological findings of the abscess from the early temporal cerebritis phase till the late full encapsulated abscess. We also succeeded in visualizing the fistula through the tegmen tympani on MR-images.
