내측 팔꿈치에 발생한 결절종에 의한 양측성 주관절터널증후군

초록

Here, we report a patient with bilateral cubital tunnel syndrome caused by both medial elbow ganglion cysts. The patient complained of paresthesia in the ring and small finger with weakness in both the hands caused by the gradual enlargement of a soft mass that was felt in both medial elbows for about three years. The patient complained of difficulty in using chopsticks and bringing the fingers together. Electrodiagnostic study revealed bilateral ulnar neuropathy at elbow level. Suspecting a ganglion cyst, an ultrasound and magnetic resonance imaging studies were performed. Aspiration of these cysts (a yellow jelly-like fluid) had improved patient’s symptom and electrodiagnostic findings in follow-up study. It is rare that a medial elbow ganglion leads to ulnar neuropathy. We report a case where the patient’s symptoms improved with conservative treatment without surgical excision.
