술후성 농성낭종에 합병된 뇌농양 1예

A mucocele of the paranasal sinus is defined as an accumulation of mucus within a sinus due to obstruction of the sinus ostium secondary to inflammation, fibrosis, trauma, previous surgery, or a mass lesion. If left untreated, it can result in intracranial infection or secondary to mass effect, result in damage to the orbits and contents of the anterior cranial fossa. Intracranial complication of infected mucocele or sinusitis, although rare today, do still develop despite widespread use of antibiotics. These include meningitis, subdural empyema, intracerebral abscess, epidural abscess and rarely cavernous or superior sagittal sinus thrombosis. Despite recent advances in treatment and diagnostic imaging, intracranial extension is often not recognized early enough to prevent delays in treatment aimed at reducing morbidity and mortality. We describe a case of infected mucocele and sinusitis associated with silent brain abscess which was treated by endoscopic sinus surgery and massive intravenous antibiotics.
