Juvenile angiofibroma (JAF) is a highly vascular benign tumor of head and neck, found mainly in adolescent males originated from the superior margin of the sphenopalatine foramen, usually spread to the pterygopalatine and infratemporal fossae (1). Intracranial extension of (JAF) occurs in 20 to 36% of patients and is almost always extradural (2). Tumor extension can occur to the middle cranial fossa and to much lesser extent to anterior cranial fossa. Extension to the middle cranial fossa can occur via the superior and inferior orbital...

This study is a retrospective one, where analysis of the clinical data of 20 adolescent males with radiologically documented and histologically proven juvenile angiofibroma was performed. Their ages ranged from 6 to 20 years with a mean age of 14.6 years. All patients were treated surgically in the period from January 1997 to March, 2015. Angiography and embolization procedures were carried out in the angiography and interventional unit. Radiology Department, Mansoura University Hospital, Mansoura, Egypt. A written consent was obtained from one of the parents...

Clinical data: This study included 20 male patients (mean age ± SD: 14.6 ± 7.2 years) with Juvenile angiofibroma and intracranial extensions. The different clinical presentation is outlined in table (1). Tumor extension and staging: Tumor staging was determined by review of the physical examination and imaging studies including CT and MRI for all patients. Extension of tumor into the middle cranial fossa was seen in 19 patients (95 %) [Right side in 11 (55 %) and left side in 8 (40 %)], while tumor...

Preoperative embolization of JAF with intracranial extension is useful in reducing the intraoperative blood loss and lowers the risk of tumor recurrence particularly in patients with large intracranial component. We recommend it as a routine preoperative adjunct in all patients of JAF with intracranial extension, however meticulous technique plus detailed analysis of the lesion and its vascular supply is a necessityfor safe embolization procedure.
