Board Review 1 – Case 13

Neuroradiology board review. This lecture is geared towards the ABR core exam for residents, but it would be useful for review for the ABR certifying exam or certificate of added qualification (CAQ) exam for neuroradiology.

More description and the answer (spoiler!) are seen below the video.

This case shows a hyperdense mass in the left posterior nasal passages. There is expansion of the left sphenopalatine foramen. In a relatively young patient, there is really only one diagnostic consideration.

The diagnosis is: Juvenile nasal angiofibroma (JNA)

Juvenile nasal angiofibromas are masses that arise in the sphenopalatine foramen in young boys. They are extremely vascular lesions and are typically treated by embolization of branches of the external carotid artery which supply the mass prior to resection.
