- Renal tuberculosis is a rare disease, which can be easily misdiagnosed. Radiologically the following conditions may mimic renal tuberculosis: chronic pyelonephritis, papillary necrosis, medullary sponge kidney, calyceal diverticulum, renal carcinoma and xanthogranulomatous pyelonephritis. A 27 year old woman presented with recurrent episodes of urinary frequency and intermittent febrile sensation. Laboratory studies for genitourinary tuberculosis showed negative results. Excretory urography and abdominal CT scan revealed the finding of abscess in cealyceal diverticulum in the right kidney. Under the clinical diagnosis of an abscess in calyceal diverticulum, right partial nephrectomy was performed. The pathologic diagnosis revealed renal tuberculosis. We report a case of renal tuberculosis mimicking abscess in calyceal diverticulum.
