Case Discussion
The case shows ultrasound findings of colovesical fistula in the patient with a history of pneumaturia.
CT scan was done later (not uploaded, no copyright). CT findings were colovesical fistula with colonic diverticular disease, right renal angiomyolipoma, and hepatic parenchymal abnormality. The patient was treated surgically. Histopathology of the resected fistula and colon did not reveal any malignancy.
