Retroperitoneal Liposarcoma on 99mTc-DTPA Renal Scintigraphy.

Retroperitoneal liposarcoma is usually large and can press on other organs. We report a case of a 66-year-old woman with a history of retroperitoneal liposarcoma resection who presented to the emergency department with abdominal pain. Ultrasonography revealed a large abdominal mass with renal displacement. Dynamic renal scintigraphy with Tc-DTPA was conducted to evaluate renal function. However, severe impairment of the right kidney function and abnormal tracer accumulation were observed during the examination. SPECT/CT was performed; 2 kidneys were successfully localized, and the recurrence of tumor was correctly detected.
