Treatment of fungal pyelonephritis and ureterolithiasis with a subcutaneous ureteral bypass system and systemic antifungal medication in a cat.

PURPOSE: We describe a case of ureteral obstruction and fungal pyelonephritis in a cat. The case was managed successfully with a subcutaneous ureteral bypass (SUB) device and systemic antifungal medication. CASE SUMMARY: A 9-year-old, male, neutered, domestic shorthair cat was referred for severe azotemia, ureteral obstruction, and sonographically identified progressive pyelectasia of the left kidney. A SUB device was placed. Cytology of the left kidney subsequently identified fungal organisms, and the cat responded clinically to treatment with fluconazole and supportive care. The cat survived for 11 months with intermittent fluconazole treatment. CONCLUSION: Fungal pyelonephritis should be considered as a possible concurrent diagnosis in cats with ureteral obstruction. The successful clinical outcome in this case suggests that treatment with SUB placement, antifungal medication, and supportive care could be an effective treatment strategy.

Multiple recurrent pancreatic cysts with associated pancreatic inflammation and atrophy in a cat.

Previous reports of true pancreatic cysts in cats have suggested that pancreatic cysts in cats are benign incidental findings. This case report describes the progressive clinical course and diagnostic findings in a cat with multiple recurrent pancreatic cysts. The presenting clinical signs included diarrhea, intermittent vomiting, polyphagia, and marked weight loss. Pancreatic cysts were identified via abdominal ultrasound and computed tomography (CT). An exploratory celiotomy and lesion histopathology confirmed multiple true pancreatic cysts of unknown etiology. One month after surgery the cat presented for lethargy and decreased appetite. Clinical re-evaluation was diagnostic for diabetes mellitus and an abdominal ultrasound confirmed recurrence of the pancreatic cysts. The recurrent nature of the pancreatic cysts and the concurrent development of diabetes mellitus were suggestive of progressive loss of pancreatic function or insulin resistance. This is the first described case of multiple recurring pancreatic cysts in a cat associated with pancreatic inflammation, atrophy and endocrine dysfunction.
