Frontal sinus osteoma complicated by extended intracranial mucocele and cerebral abscess: neurosurgical strategy of a rare clinical entity.

摘要

The combination of paranasal sinus osteoma, mucocele and brain abscess is rare. Only one other case has been reported so far, where the cerebral abscess was diagnosed intraoperatively. We report here on a second patient with combined frontal sinus osteoma, intracerebral mucocele as well as cerebral abscess. However, in our case, the diagnosis of cerebral abscess was reached prior to surgery, which allowed for a tailored treatment strategy with abscess puncture under neuronavigational guidance and, after 3 weeks of antibiotic therapy with documented abscess shrinkage, osteoma and mucocele resection as well as reconstruction of the eroded dura.
