Plain-English summary

A 6-year-old Persian cat was brought to the vet for constipation, not eating, and vomiting. The vet discovered that these symptoms were caused by a pseudomycetoma, a type of fungal infection that created a mass in the cat's colon and caused a blockage. Ultrasound and CT scans helped identify the mass and its extent. Treatment typically involves addressing the fungal infection, and with proper care, the cat can recover from this condition.

Abstract

A 6-year-old Persian cat was examined for constipation, anorexia, and vomiting that was subsequently found to be due to a pseudomycetoma originating from the descending colon and sublumbar region, and causing mechanical obstruction of the colon and rectum. Multiple discrete hyperechoic foci likely representing fungal grains within the lesion gave the mass a coarse echotexture on ultrasound and was supportive of the diagnosis and computed tomography allowed delineation the extent of the mass. A pseudomycetoma is a granulomatous/pyogranulomatous reaction that surrounds dermatophytic fungal hyphae. Definitive diagnosis of a dermatophytic pseudomycetoma requires identification of the etiologic agent by cultivation or immunohistochemical staining. A pseudomycetoma should be included in the differential diagnosis for an abdominal mass in a Persian cat, especially is accompanied by the sonographic findings noted above.
