Cryptococcus gattii thigh abscess

Magnetic resonance imaging scan, showing a 5x4x4 cm mass in the inner mid right thigh involving the adductor magnus muscle. The mass had mild heterogeneous enhancement on T2 imaging and changes consistent with limited surrounding edema. Histopathology from a percutaneous biopsy demonstrated soft tissue necrosis and thick-walled, encapsulated organisms that stained with Gomori methenamine silver and mucicarmine. The mass was surgically resected and cultures grew Cryptococcus gattii.
