Postoperative lymphocele demonstrated by lymphoscintigraphy SPECT/CT.

Lymphoscintigraphy is a useful and safe tool for the diagnostic evaluation of a swollen extremity as well as sentinel lymph node biopsy in malignancies. Here, we report a 34-year-old woman who developed progressive abdominal distention and bilateral lower limb edema 3 months after simultaneous pancreas and renal transplantation. Color Doppler-duplex ultrasound revealed patent deep veins of bilateral lower extremities without evidence of thrombosis. Lymphoscintigraphy demonstrated a large area of tracer accumulation at left lower quadrant of abdomen, suggestive of a postoperative lymphocele. SPECT/CT successfully localized the lesion near the renal graft.
