Gd-DTPA-enhanced MR imaging of cryptococcal meningoencephalitis.

This report describes magnetic resonance (MR) imaging of biopsy-proved cryptococcal central nervous system (CNS) infection in a 31-year-old HIV negative man. Initial MR imaging revealed multi-focal Gd-DTPA enhancement and showed more lesions than contrast enhanced CT. The lesions regressed after antifungal therapy. MR imaging aids in diagnosis as well as helps to monitor the response to the pharmacological therapy of cryptococcal meningoencephalitis and possibly provides valuable insights into the pathophysiology of this condition.
