Malignant transformation of abdominal wall endometriosis is extremely rare. We describe FDG PET/CT findings in a case of clear cell carcinoma arising from abdominal wall endometriosis with multiple lymph node metastases. The primary tumor was located at the site of the prior cesarean section and showed intense FDG activity with a SUVmax of 26. The metastatic lymph nodes in the bilateral inguinal and pelvic regions showed variable FDG-activity. This case indicates that malignant transformation of abdominal wall endometriosis should be included in the differential diagnosis of FDG-avid lesions in the abdominal incisional site.\nThis case report describes an extremely rare cancer (clear cell carcinoma) that developed from abdominal wall endometriosis at a prior cesarean section scar. FDG PET/CT showed the primary tumor with intense FDG uptake and a SUVmax of 26, and multiple metastatic lymph nodes in the bilateral inguinal and pelvic regions with variable FDG activity. These imaging findings demonstrate that malignant transformation of abdominal wall endometriosis can present as FDG-avid lesions at abdominal incision sites. Clinicians and radiologists should consider this diagnosis when evaluating FDG-avid masses in surgical scars, especially in patients with a history of endometriosis.\nText is machine generated and may contain inaccuracies.
