Multimodality imaging of renal inflammatory lesions

Figure 17 Renal tuberculosis. A: Delayed CECT shows a cavitation at the lower pole of right kidney communicating with the PCS. This finding is fairly typical of GU TB. This adolescent male was a known case of pulmonary tuberculosis; B: Plain abdominal radiograph in a different patient shows diffuse parenchymal calcification of right kidney suggestive endstage autonephrectomy or putty kidney; C: Volume rendered technique image of delayed phase CECT shows a contracted thimble bladder (arrowhead), hiked up right pelvis (arrow) and hydroureteronephrosis. This patient had acid fast bacilli cultured from urine. PCS: Pelvicalyceal system; CECT: Contrast-enhanced computed tomography; TB: Tuberculosis.
