Squamous Carcinoma of the Lung Presenting as Migraine-Type Headache: A Case Report

Abstract

Introduction: Orthostatic hypotension has long been recognised as a paraneoplastic effect of lung cancer. Lung cancer presenting with orthostatic hypotension and migraine-type headaches has not been previously described in the literature. Case Report: A 62-year-old Caucasian male presented with headaches, typical of his migraine, after a 30-year migraine-free period. An examination revealed a significant postural drop in BP with reflex tachycardia and no other features of dysautonomia. Investigations showed a metastatic squamous cell lung cancer. Pharmacological treatment of orthostatic hypotension resolved the migraine-type headaches. Discussion: Orthostatic hypotension is associated with lung cancer. Prompt pharmacological treatment in patients not responding to non-pharmacological therapy can provide relief from disabling symptoms of orthostatic hypotension. In this patient, this included symptoms consistent with migraine-type headaches.
