DSA (angiography) - DSA of the right external carotid artery
Lateral External carotid artery
Lateral External carotid artery
Would a biopsy be helpful in this case?
No! This is a case of juvenile nasopharyngeal angiofibroma with classical clinical and imaging findings. These highly vascular tumors are prone to significant haemorrhage and biopsy is contraindicated due to risk of exsanguination.
True or false: This lesion is more common in males?
True, this lesion is almost exclusively seen in males.
Selective injection of the right external carotid artery demonstrates a hypervascular tumor blush supplied by posterior sphenopalatine branches of the right right internal maxillary artery.
Control angiography after embolization of the distal right internal maxillary artery demonstrates minimal opacification of the previously seen hypervascular blush.
