Deformed bladder activity mimicking pelvic crossed ectopic kidney on Technetium-99m labelled dimercaptosuccinic acid renal cortical scintigraphy

Abstract

Technetium-99m dimercaptosuccinic acid (DMSA) scan was performed on a 32-year-old woman with abdominal pain. A normal functioning slightly ptotic right kidney was seen on planar images. There was no activity in the left renal region and a small fusiform activity was seen in the right pelvic area. Pelvic computed tomography (CT) axial images revealed pre-vesical pelvic abscess pushing the bladder posteriorly to the right side. On computed tomography images obtained after percutaneous drainage it was concluded that the activity in the right pelvic area on Technetium-99m DMSA scan was compatible with physiological activity in the bladder.
