Non-traumatic cerebrospinal fluid rhinorrhea caused by ethmoid sinus osteoma
Date of this Version
Cerebrospinal fluid (CSF) rhinorrhea is a rare complication of ethmoid sinus osteoma, considering its benign and indolent nature. We present a 36-year-old female patient with symptomatic CSF rhinorrhea as a primary presentation of ethmoid sinus osteoma. We have highlighted the imaging features and emphasised the importance of imaging in the diagnosis of spontaneous CSF leak.
