Case Discussion

Pathologically proved pelvic ganglioneuroma

Ganglioneuromas are usually asymptomatic and often discovered incidentally as they are slow-growing and generally endocrinologically inactive 1. They are typically seen as well-circumscribed encapsulated masses that are iso to hypoattenuating to muscle. The lesion may also demonstrate calcifications (~20%) which are generally fine and speckled but may be coarse 2.
