Plain-English summary
A 5-year-old female neutered Persian cat was brought to the vet with painful urination, blood in her urine, and a blockage in her urinary tract that had been getting worse over several months. Tests showed she had high potassium levels and kidney issues, and an ultrasound found a mass near her bladder. A biopsy revealed the mass was caused by a type of fungus called Penicillium. The cat was treated with itraconazole, which helped her symptoms initially, but sadly, she later died from severe anemia. A necropsy confirmed the fungal infection and kidney damage.

Abstract
A 5-year-old, female neutered Persian cat was admitted to the Small Animal Hospital (Chulalongkorn University, Bangkok, Thailand) with clinical signs of dysuria, haematuria and partial urethral obstruction that had manifested over several months. The animal also had hyperkalaemia and severe azotaemia at the time of presentation. Urinalysis showed haematuria, pyuria and the presence of several transitional cells. In addition, ultrasonography demonstrated an extraluminal mass between the neck of urinary bladder and the colon. Fine-needle aspiration of the mass revealed a fungal form with branching and septate hyphae. Consequently, itraconazole treatment was prescribed and clinical signs of improvement were seen after 7 days. However, 1 month later, the cat died of acute anaemia. Necropsy revealed the presence of extraluminal multifocal fungal granuloma at the neck of the urinary bladder, and contracted kidneys. Histopathological analysis of the fungal granuloma was found to be composed of branching, septate hyphal fungi together with inflammatory cells. Subsequent fungal culture and identification revealed this to be a species of Penicillium.
