736 Endoscopic-Guided Decompression of an Incidental, Massive, Infected Fronto-Ethmoidal Mucocele: Our Experience

Abstract A 55-year-old man was referred to neurology with worsening headaches and right-hand numbness. An MRI brain demonstrated a hemangioblastoma but also large right sided frontoethmoidal mucocele. The only sino-nasal symptom the patient had unilateral nasal obstruction felt this well-controlled steroid spray prescribed in primary care. Nasendoscopy showed pus emanating from smooth mass anterior cavity. CT scan features of large, expansile extending across both frontal ethmoid sinuses, lateralising septum, dehiscence lamina papyracea. underwent image-guided endoscopic sinus surgery drain mucocele which filled considerable amount seen have eroded all lamellae. Sinonasal mucoceles are collections mucous, lined epithelium, thought be more common third fourth decades (1). They usually caused by as result an obstructed sinuses can follow trauma, inflammation or occur spontaneously (2). Once identified, is standard care prevent complications expansion infection. In case report, along imaging intraoperative photographs, we further describe our approach experience managing
