Axial section in computed tomography demonstrating obliteration of the nasal cavity and maxillary sinus. The 13 patients were given case numbers from 1 to The extent of growth of JNA was studied both clinically using nasal endoscopy, posterior rhinoscopy and radiologically by contrast enhanced CT scanning or magnetic resonance imaging MRI of para nasal sinuses.
Advanced JNA is much more difficult to treat. 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.
