ABSTRACT
A 12-year-old girl presented with headache, nasal voice, and anosmia. Magnetic resonance imaging demonstrated a 11 × 9 × 8-cm tumor extending from the nasal cavity to the frontal lobes. Histological analysis was consistent with transitional meningioma WHO grade I. As far as we know, this is the first reported case of a giant olfactory groove meningioma invading the nasal cavity through the anterior cranial base. Complete surgical removal was accomplished with excellent result via a staged endoscopic and transcranial approach. A microvascularized vastus laterallis flap was used for reconstruction. Surgical options and technical details in the management of this lesion are reviewed.
