A Case of Vagal Cephalgia as a Manifestation of a Lung Neoplasm -- A Case Report and Review of Literature

Abstract

Lung cancer can present with unilateral atypical facial pain, a rare symptom due to vagus nerve involvement or paraneoplastic syndrome. This manifestation is usually missed, delaying the diagnosis and prognosis. We discuss a case of a 45-year-old male who presented with right-sided hemifacial pain and with normal neurological investigations.
