title: An antecubital fossa "cyst" caused by postoperative kinking of the brachial artery.
abstract: A 77-year-old woman was referred to our staff for evaluation of a "cystic" mass in the antecubital fossa. The recent medical history included surgical excision of a median-nerve schwannoma. The postoperative course had been uneventful. The sonographic examination revealed kinking of the brachial artery; color Doppler imaging showed aliasing at the level of the kink. The case illustrates the value of ultrasound in the diagnosis of fluid-filled lesions of the elbow, including those that are rare and unexpected.
