Sonographic features of ovarian remnants

Area of Science:

• Gynecologic Imaging
• Pelvic Surgery Complications

Background:

• Ovarian remnants are unintentional portions of ovarian tissue remaining after oophorectomy.
• They can be functional, cystic, and lead to pelvic pain or ureter compression.
• Often associated with adhesions from prior pelvic surgery or endometriosis.

Purpose of the Study:

• To describe the sonographic features of ovarian remnants.
• To evaluate diagnostic criteria and potential interventions for ovarian remnants.

Main Methods:

• Retrospective study of 10 patients with surgically or clinically confirmed ovarian remnants.
• Analysis of sonographic characteristics including cyst morphology and presence of vascularized tissue.
• Review of treatment outcomes, including aspiration and medical management.

Main Results:

• Most ovarian remnants appeared as simple cysts (7/10), with some having septations (3/10).
• Six remnants showed a rim of vascularized ovarian tissue.
• Symptomatic relief was achieved in 3/3 patients after aspiration; one patient with ureter compression improved with GnRH agonist therapy.

Conclusions:

• Sonographic findings of a cystic or multiseptated pelvic mass with a vascularized rim in post-oophorectomy patients suggest ovarian remnant.
• Sonographically guided aspiration can offer symptomatic relief for ovarian remnants.
• Ultrasound is valuable for monitoring patients undergoing medical treatment for ovarian remnants.
