An isolated cryptococcal urinary tract infection in a cat.

A male domestic shorthaired cat was presented for evaluation of stranguria and pollakiuria. A cryptococcal urinary tract infection (UTI) was diagnosed cytologically and via fungal culture. No evidence of systemic involvement was found. Chronic renal failure was a concurrent disease in this cat. Treatment consisted of oral fluconazole. Clinical signs resolved after 2 weeks of therapy, and fluconazole was discontinued after 6 months when negative urine culture results indicated resolution of the infection. This case demonstrates that correct identification of cryptococcal UTI allows for administration of therapy that can be associated with resolution of clinical signs.
