A Real Headache: Intracranial Extension and Epidural Abscess As Complication of Chronic Mucocele.

Mucoceles are benign lesions of salivary glands typically originating from the paranasal sinuses. Intracranial extension and superinfection of these lesions are rare but serious complications of chronic mucoceles. Here, we discuss a patient with a known mucocele, initially lost to follow-up, who presented three years later with headache, purulent rhinorrhea, and intracranial extension of his mucocele with development of an epidural abscess. This case highlights the potential complications of chronic, large mucoceles and emphasizes the importance of thorough evaluation in patients with facial abscesses in the setting of known sinus pathology. Any mucocele with signs of superinfection such as purulent rhinorrhea, abscess near the sinuses, or refractory symptoms should warrant cranial imaging. Mucoceles with evidence of intracranial extension require neurosurgical and/or otolaryngologic evaluation for evacuation and debridement to avoid neurologic injury or devastating infection.
