Suprapubic cartilaginous cyst

Suprapubic cartilaginous cysts (SPCC) are rare cystic lesions arising from the symphysis pubis thought to be degenerative in origin. They have also been called retropubic or subpubic cysts.

In the small number of cases in the literature, all bar one patient, have been female. The majority were multiparous and post-menopausal.

The cyst contains mucinous degenerative contents within a fibrocartilaginous capsule.

Asymptomatic or causes pelvic pain, urinary voiding symptoms, a vulvar mass, or even dyspareunia

Ultrasound

Cystic structure usually posterosuperior to the symphysis pubis

CT

Exophytic cystic structure arising from the symphysis pubis usually located anterior to the urinary bladder; it can contain small foci of nitrogen gas from the degenerative fibrocartilaginous disc of symphysis pubis (as part of the vacuum phenomenon of degenerative joint disease).

MRI

Fluid signal (i.e. low T1W and high T2W signal) of the contents with an enhancing thin wall post-contrast administration.

Surgical resection has been employed successfully in symptomatic patients. Aspiration and steroid injections have also been tried.

Suprapubic cartilaginous cysts were first described in 1996 by two pathologists at the University of Manitoba, Drs Antonio Alguacil-Garcia and Charles Littman 4.
