Histopathologically JNA shows a fibrocellular stroma with spindle cells and haphazardly arranged collagen interspersed with an irregular vascular pattern. Treatment for Nasopharyngeal angiofibroma JNA is primarily surgical. Intraoral view showing swelling on the upper left side of the maxilla and obliteration of the vestibule. Sign up for our Email Newsletters. JNA is classified as Type I when the tumor is restricted to the nasal cavity and the nasopharynx without bone destruction, Type II when the tumor invades the pterygomaxillary fossa and maxillary, sphenoidal and ethmoid sinuses with bone destruction, Type III when the tumor invades the infratemporal fossa, the orbit, and the parasellar region but remains lateral to the cavernous sinus and Type IV when the tumor invades the cavernous sinus, the optic chiasma and the pituitary fossa.
The classification and clinical staging is relatively easy and helps to plan treatment and determine prognosis.
Juvenile nasopharyngeal angiofibroma
Continuous growth involves the sphenoidal sinus, nasal fossa and middle turbinate, pterygomaxillary fossa and the posterior wall of the maxillary sinus as seen in the present case. J Clin Imaging Sci.
Typically a lobulated non-encapsulated soft tissue mass is demonstrated centred on the sphenopalatine foramen which is often widened and usually bowing the posterior wall of the maxillary antrum anteriorly.

Biological distinctions between juvenile nasopharyngeal angiofibroma and vascular malformation: These techniques help to establish the exact site, extension and relation of the tumor to the adjacent structures such as blood vessels and nerves. The origin and development of JNA is not fully understood.
Type III is a calabash-like massive tumor lobe in the middle cranial fossa. MRI is superior to CT for detecting soft tissue extension of the tumor intracranially.
Computed tomography CT scan showed the presence of a soft tissue mass involving the maxillary sinus, nasal cavity, and nasopharynx. Extensive bony destruction is usually not a feature, but rather bone is remodelled or resorbed. Extended osteoplastic maxillotomy for total excision of giant multicompartmental juvenile nasopharyngeal angiofibroma.
DSA digital subtraction angiography of carotid artery to see the extension of tumors and feeding vessels. A higher density toward the periphery is noted, which was seen in the present case naeofaring. CT images show a heterodense mass that is centered in the sphenopalatine foramen.
Biopsy should be avoided as to avoid extensive bleeding since the tumor is composed of blood vessels without a muscular coat.
This feature may be helpful is differentiating from other angiofibrooma aggressive lesions. A wait and watch policy with periodic imaging may thus postpone or eliminate the need for surgery and reduce morbidity. They account for only 0. Although these masses are thought to arise from the region of the sphenopalatine foramenthey are usually sizeable at diagnosis, frequently with extension medially into the nasopharynxlaterally into the pterygopalatine fossa and over time beyond, into the orbitparanasal sinusesintracranial cavity and infratemporal fossa.
