title: Vascular malformation of the sphenoid sinus.
abstract: Isolated sphenoid sinus lesions are usually inflammatory lesions or mucoceles. We report an unusual case of a thrombosed arteriovenous malformation presenting as a unilateral primary vascular malformation of the sphenoid sinus. To the best of our knowledge, no one has ever reported such an entity in the medical literature. Differential diagnosis of sphenoid sinus lesions and possible etiologies for this case will be detailed.
