Lipoleiomyoma Causing Adnexal Torsion

Abstract

Abdominal pain in women of reproductive age is a frequently encountered chief complaint in the emergency department. Adnexal torsion is a time-sensitive diagnosis that is essential for emergency physicians to consider in the initial differential diagnosis. Bedside sonography can be used to assist the clinician in the detection of adnexal masses placing the patient at risk for torsion. Lipoleiomyomas are uncommon, benign neoplasms consisting of variable portions of mature lipocytes, smooth muscle, or fibrous tissue. Very few cases have been reported, with no cases previously reported by emergency physicians using bedside ultrasound. A case is presented of a middle-aged woman who presented to the emergency department with acute lower abdominal pain. At the time of the initial history and physical examination, bedside screening sonogram was performed, which allowed rapid diagnosis of a large, heterogeneous, relatively avascular adnexal mass that was later identified as a lipoleiomyoma, a rare adnexal neoplasm, that resulted in adnexal torsion.
