title: Transnasal endoscopic approach for anterior skull base angiomatosis complicated by a meningocele.
abstract: A 42-year-old woman presented with symptoms of left-sided nasal obstruction, cerebrospinal fluid (CSF) rhinorrhea, and frequent sinus infections. Radiologic investigation revealed a tumor destructing the left cribriform plate and forming opacifications in the olfactory area. She had left-sided submucosal meningocele, deviating the septum to the right side. Intracranial involvement was not observed. Under endoscopic visualization, the tumor and the meningocele was meticulously dissected and excised using bipolar cautery. The CSF fistula in the anterior skull base was repaired with the same approach. Thanks to increasing experience with endoscopic sinus surgery, excision and removal of noncomplex tumors of the anterior skull base have become possible. This case report illustrates transnasal endoscopic approach to the anterior skull base using minimally invasive technique.
