Clinical, surgical and pathologic findings of adnexal torsion in pregnant and nonpregnant women.

A series of 101 patients with adnexal torsion during a 12 year period are reviewed. Twenty patients were pregnant at the time of diagnosis and underwent surgical treatment. Preoperatively, the correct diagnosis was not established in four pregnant patients and in 30 nonpregnant patients. An operation was usually delayed for more than 24 hours. Unwinding of the twisted adnexa, regardless of its appearance, was the main surgical procedure in both groups. The outcome of the pregnancies was favorable. The main histopathologic findings in both groups were cysts of the follicular or corpora lutea.
