Renal Cell Carcinoma
Kidney mass detected on ultrasound doubles in size over nine months
This primary care provider could not feel these patients during a normal pelvic exam ovaries and ordered an abdominal ultrasound, which revealed a tumor on the right kidney. The tumor was initially diagnosed as an angiomyolipoma.
Four months later, a second ultrasound confirmed an 8-mm echogenic nodule. A triphasic renal CT with IV contrast ordered nine months later to confirm the angiomyolipoma revealed a fat-poor, hypovascular tumor that enhanced from 34 to 70 Hounsfield units. In comparison with previous ultrasound studies, it appeared to have more than doubled in size to 1.6 cm. The decided diagnosis was renal cell carcinoma.
After partial nephrectomy, kidney function was normal.
