Secondary cluster headache and numb chin syndrome as initial manifestation of high-grade B-lymphoma: a case report

Abstract

Background: Cluster headache is a primary condition characterized by severe headache accompanied by trigeminal autonomic signs. By definition, it is not attributed to underlying etiologies; however, under certain clinical characteristics, secondary etiologies must be ruled out. Case presentation: We present the case of a 48-year-old Hispanic man with a history of episodic right orbital pain, lasting 30 minutes, associated with ipsilateral tearing, who prior to the onset of his symptoms reported loss of appetite, weight loss, and paresthesias in the right chin region. After work-up studies, high-grade lymphoma with infiltration to the right submental nerve was diagnosed, in which numb chin syndrome was the initial presentation. Despite initiation of treatment, the patient died 3 weeks after the diagnosis. Conclusions: In the study of cluster headache, underlying etiologies must be considered when there are atypical clinical manifestations. Within these etiologies, metastases to pericranial nerves must be included, which, besides generating localized symptoms, can activate the trigeminal vascular system simulating headaches of primary etiology.
