Pancoast Tumor Presenting as Arm Pain: Case Report

Abstract

Pancoast tumor is a bronchial carcinoma which can cause upper extremity pain due to the infiltration of the lower trunk of the brachial plexus. Here, we describe a case of Pancoast tumor, a fifty years old man, presenting as upper extremity pain. The elektrophysiologic findings suggested lower trunk brachial plexopathy that could not found in the earlier investigations. The radiologic investigations showed tumor at the pulmonary apex at the left side. This case is reported to emphasize the importance of needle EMG in the diagnosis of brachial plexopathy and to emphasize the necessary of thinking brachial plexopathy in the patients who admit with shoulder and arm pain.
