Plain-English summary

A 2-year-old female neutered golden retriever was brought in because of an unusual mass in her abdomen. After imaging and a biopsy, the mass was identified as a fungal infection called eumycotic mycetoma, caused by a fungus known as Penicillium duponti. The vet performed surgery to remove the mass and the affected kidney, and later, when the dog had another mass in her spleen, they did another surgery to remove it. She was then treated with an antifungal medication called itraconazole. Two years later, she showed no signs of illness, except for some mild increased thirst.

Abstract

A 2-year-old female neutered golden retriever was presented for investigation of an intra-abdominal mass. Computed tomography revealed a mass associated with the caudal pole of the right kidney. Incisional biopsy findings were consistent with eumycotic mycetoma. The mass was subsequently removed in conjunction with right ureteronephrectomy. Two years later, the dog re-presented with a splenic mass and fungal plaques located throughout the peritoneum. Splenectomy was performed and the mass was diagnosed as eumycotic mycetoma caused by Penicillium duponti. Indefinite systemic treatment with 10 mg/kg itraconazole orally once a day was initiated. Thirty-two months after the last surgery, there were no clinical signs apart from mild polydipsia. Haematology and biochemistry results were unremarkable. To the authors' knowledge, this is the first report of successful treatment of intra-abdominal eumycotic mycetoma with a combination of surgery and systemic antifungal therapy in the dog. Penicillium duponti has not apparently been reported to cause disease in animals or humans.
