Strategic multidisciplinary management of pelvic carcinosarcoma: Emphasizing advanced diagnostic imaging and staged...

Pelvic carcinosarcoma is an aggressive malignancy with significant diagnostic and management hurdles due to its complex vascularity and potential for extensive local invasion. A 59-year-old female presented with severe abdominal pain and significant weight loss, leading to the discovery of a large, complex pelvic mass through CT scans, MRI, and PET CT, suggesting aggressive malignancy. Initial management included a robotic laparoscopic proximal sigmoid loop colostomy to alleviate obstruction. Significant vascularity led to consultations with Vascular Surgery and subsequent preoperative embolization. Definitive surgery involved a supralevator posterior exenteration for en bloc resection of the vagina, mass, and sigmoid colon, combined with a low anterior resection and an omental J flap in anticipation of potential postoperative radiation therapy. This case underscores the importance of integrated imaging and staged surgical interventions in managing pelvic carcinosarcoma, emphasizing a multidisciplinary approach to optimize outcomes and minimize complications.
