A Cerebrospinal Fluid Leak Following Endoscopic Resection of a Frontal Sinus Osteoma

A 55-year-old woman presented with a 5–6 month history of focal right frontal pressure that was partially relieved with over-the-counter (OTC) analgesics. She had mild issues with nasal congestion and obstruction; however, she denied discolored nasal discharge or significant problems with her sense of smell. She was evaluated for migraines by a neurologist who ordered an MRI, and this MRI revealed a right frontal sinus osseous lesion that was associated with post-obstructive secretions. She had been treated with antibiotics and steroids by her primary care doctor as well as two otolaryngologists. Each otolaryngologist recommended surgery, but recommended a rhinologist perform the procedure.
