Complex space of Retzius lymphocele resulting in iliac compression and submassive pulmonary embolism after robotic Retzius sparing prostatectomy

Abstract

Lymphoceles are common following prostatectomy with lymph node dissection, but the vast majority are asymptomatic. We present a unique case of a large complex lymphocele tracking into the anterior space of Retzius following Retzius sparing prostatectomy and bilateral pelvic lymphadenectomy. The patient initially presented with shortness of breath and subsequent diagnosis of a submassive pulmonary embolism. Further evaluation revealed compression of the iliac vessels by the fluid collection. Following multiple failed attempts of drainage percutaneously, the patient required return to the operating room for peritoneal marsupialization, drainage of fluid collection, and evacuation of large amounts of clot within the collection.
