Tubo-ovarian abscess

Case contributed by Ian Bickle


Abdominal pain with palpable pelvic mass.

Patient Data

Age: 55 years
Gender: Female

Ultrasound performed by gynecologist prior to MRI request - query degenerative fibroid

Multi-septated thick walled mass on the left side of the pelvis, displacing the uterus medially.  This contains focal cystic filled spaces, which exhibit diffusion restriction.  The wall and septa of the mass avidly enhance. Perilesional free fluid.  Ovary not separately identified.

Case Discussion

The appearances of the left sided pelvic mass are consistent with a tubo-ovarian abscess.  The diffusion restriction of the internal contents are similar to those observed in other body systems, such as the brain, in the context of an abscess.
