Diagnosis

Angiofibroma

Findings

CT – Axial post-contrast image of the face demonstrates complete opacification of the right maxillary antrum with marked thinning and erosion of the posterior-lateral wall.

MRI – Coronal T2 and coronal and axial fat-suppressed post-gadolinium T1 images show a lobulated soft tissue mass within the right maxillary sinus with extension through the posterior aspect of the sinus into the nasal cavity, nasopharynx, pterygopalatine fossa, and infraorbital fissure and occasional flow voids.

Discussion

Angiofibroma is a benign but aggressive hypervascular mass which grows through the pterygopalatine canal and extends into the infratemporal fossa. This is the most common benign tumor of the nasopharynx. Nearly exclusive in adolescent males. MR is best to see full extent of the lesion. Flow voids and enhancement are common. Preoperative endovascular endovascular embolisation is often necessary to minimize blood loss during surgical resection.
