more fibrous tissue than capillary hemangiomas (figure

fibrocytes in a varying amount of connective tissue

Three years following surgery the patient remains
tumour free.
DISCUSSION
Reports of extranasopharyngeal angiofibroma have
appeared sporadically in the literature. From these it is
evident that extranasopharyngeal angiofibromas occur in
an older age group than nasopharyngeal angiofibromas.
Also, the male sex preponderance of the nasopharyngeal
angiofibromas is not shared by the extranasopharyngeal
angiofibromas. Extranasopharyngeal angiofíbromas have
heen reported from many sites in the head and neck

the maxillary sinus.
Imaging is extremely important in the diagnosis and
management of these tumours. The characteristic
pattern of spread, angiographic appearance, and clinical
situation generally obviates the need for a biopsy.
CT, MRI, and angiography are the primary imaging
modalities for the identification of these tumours.
Although this lesion is microscopically benign, it may
have an aggressive clinical course extending out of
the bony vault of the nasopharynx to compromise
vital structures if untreated. In the clinical setting, it is
important to distinguish angiofibromas from capillary
hemangiomas because of the different natural history

the excellent results with modern surgical techniques,
the addition of CT-based tumour mapping, and
concerns regarding the late effects of radiation therapy,
the standard of care has become surgical excision
of resectable tumours. The use of primary radiation
therapy is usually described only for tumours that
are considered to be unresectable on the basis of CT
criteria.
To date few reports of angiofibromas arising in the nasal
cavity have appeared in the literature, and the nasal
septum represents an extremely rare localization.
