Lymphoscintigraphic demonstration of chyle leak after kidney transplantation and gamma camera detection of radioactivity in chylous aspirate.

Iatrogenic chyle leak with chyloma formation is a rare complication of kidney transplantation resulting from injury to the lymphatics. We present a case of a 53-year-old man who complained of right leg swelling 2 months after kidney transplantation for chronic renal failure. Abdomen CT showed loculated fluid collection around the transplanted kidney. Lymphoscintigraphy demonstrated chyle leak in the right iliac fossa, and subsequent ultrasound-guided aspiration of the chyloma showed radioactivity as detected by gamma camera. After drainage insertion, the amount of collected fluid gradually decreased, and right leg edema was relieved.
