Śluzowiak zatoki czołowej penetrujący do jamy czaszki

Abstract

We discuss a case of 49-year-old man admitted to our Department with headache and tumor of frontal region since 3 months. We report clinical features and imaging data of mucocele of frontal sinus that penetrates into cranial cavity. The mucocele had damaged anterior and posterior walls of frontal sinus with intracranial penetration. There was intact dura of anterior fosse. External approach with coronal incision was performed, mucocele was evacuated and mucosa was removed. Then frontal sinus was cranialized with reconstruction of anterior wall and finally wide nasal drainage was performed. Intracranial mucocele of the frontal sinus is rere evidence. The key difficulties may be related to dura preservation and reconstruction of anterior wall of frontal sinus.
