Spontaneous Cerebrospinal Fluid Rhinorrhea as the Primary Manifestation of Maxillary Carcinoma

—Case Report—

Abstract

A 66-year-old man presented with a maxillary carcinoma manifesting as unrelenting spontaneous cerebrospinal fluid (CSF) rhinorrhea. Anterior craniofacial resection of the tumor was performed with multilayered repair of the dura mater. Maxillary carcinoma usually manifests as nasal blockage, epistaxis, or a mass lesion. This case highlights the necessity for a high index of suspicion for malignant tumor and the need for meticulous repair of the dura mater to seal off the CSF leakage.
