Abstract
Plexiform schwannoma (PS), a subtype of schwannoma, is a rare benign nerve sheath tumor characterized by a multinodular plexiform growth pattern. It is usually confined to the head and neck or skin. Pelvic PS is an extremely rare occurrence and signifies a challenge for the imaging diagnosis. In this work, we present a 42-year-old woman with pelvic PS, who was initially suspected of malignant tumor on 18F-FDG PET/MRI but confirmed as PS by postoperative pathology. We consider that this case would contribute to the literature and provide a further insight into diagnosing this kind of rare tumor.
