Imaging diagnosis-intracranial cryptococcal mass in a cat.

A 4-year-old neutered female domestic shorthair was evaluated for mentation changes and left prosencephalic signs. This imaging report describes the imaging findings for this patient. A diagnosis of a cryptococcal mass was made based on imaging and additional diagnostics. Complete resolution of the mass was demonstrated by follow-up imaging. This report serves as a reminder that masses associated with cryptococcal infection should be included on the differential list for cats with intracranial masses. In addition, this report provides evidence that large intracranial cryptococcal masses may resolve with long-term medical therapy.
