A Case of Pancoast Tumor with Unusual Presentation

Abstract

Introduction The Pancoast syndrome (PS) has been termed after Henry Pancoast. Its neurologic core symptoms include pain, radicular sensory and motor syndromes, and Horner syndrome. A PS is often the presenting sign of lung cancer and bears a grim prognosis.

Methods This case report describes an atypical onset of a lung tumor causing a PS. Electrophysiological examination was not conclusive. The diagnosis was confirmed by MRI, CT scan, and biopsy. The intervention consisted of preoperative chemo- and radiotherapy and was followed by an extensive surgical approach with histologically confirmed perineural invasion of the brachial plexus.

Results The postoperative period was dominated by neuropathic pain. Despite considerable loss of distal sensorimotor function of the right hand, the patient uses the extremity and has returned to professional life.

Discussion This observation triggered by the advances in general oncology and surgery also demonstrates the management of a lesion of the peripheral nervous system caused by cancer.
