Presentation
Left lower abdominal pain. History of caesarean section 2 years prior.
Patient Data
Large well-circumscribed ovoid mass in the left upper pelvic region of intermediate to high signal on T1 and high signal on T2, containing serpiginous structures of intermediate to low signal on T2, with peripheral enhancement on postcontrast sequences (granuloma). No pelvic lymphadenopathy or free fluid in the peritoneal cavity.
Normal appearance of the uterus and ovaries.
Case Discussion
The clinical history and MRI features are most consistent with a gossypiboma that was confirmed at surgery (laparoscopic approach) as a surgical gauze.
