Ovarian Remnant Syndrome: Difficulties in Diagnosis and Management

Ovarian remnant syndrome should be considered in the differential diagnosis of pelvic pain with a mass in a patient who has had extirpative surgery. Although rarely reported in the literature, it is probably much more prevalent than is suspected. Most commonly, the initial surgery was performed for endometriosis or pelvic inflammatory disease, with incomplete excision of the ovaries. Surgical excision of the ovarian remnant, the definitive treatment, is itself difficult, and is often attended by serious complications. Medical therapy is empiric, and hormonal manipulation may help prevent recrudescence. Three cases are reported, their pathology and the literature is reviewed.
