Imaging in retropubic cartilaginous cyst

Abstract

The retropubic cartilaginous cyst is a benign slow-growing degenerative lesion arising from the fibrocartilage of the pubic symphysis. Degeneration is secondary to multiparity or pelvic trauma. The symptoms are commonly urinary tract-related and vary depending on the location. A confident diagnosis can be made on MRI demonstrating typical continuity with the pubic symphyseal joint, pubic diastasis, and cartilage signal. Management is typically conservative, with large lesions and failed conservative treatment requiring excision.
