BackgroundThe diagnosis of adnexal torsion is difficult to make on the basis of symptoms, physical findings or radiologic techniques. Unfortunately, delayed intervention can lead to irreversible damage and loss of the adnexa. This report describes a finding seen on computed tomography (CT) that may increase suspicion of the diagnosis of ovarian torsion.CaseA 21-year-old woman was admitted with constant abdominal pain and a tender retrouterine mass. Ultrasound failed to provide a definitive diagnosis. CT showed a central, hypodense area consistent with fat and surrounded by a shell of intermediate density. At laparotomy the patient was found to have a necrotic left adnexa due to torsion. Bisection of the adnexal mass confirmed a dermoid cyst with overlying edematous ovarian cortex.ConclusionThe observation of a round, hypodense central lesion (dermoid cyst) surrounded by thickened, edematous ovarian cortex on CT is a finding that may aid in the diagnosis of adnexal torsion. The finding is a thickened shell of ovarian cortex surrounding a central mass that has caused the torsion; in this case it was a dermoid cyst.
