Abstract

To report a case of an accessory canal arising from the floor of the foramen rotundum (FR) and extending to the infratemoral fossa. This case report describes the imaging findings of FR duplication on high-resolution CT in multiple planes. The FR is formed when the foramen anterius lacerum is divided into the superior orbital fissure and the FR inferiorly by an osseous spur arising from the sphenoid body. It has been hypothesized that FR duplication/fenestration, and accessory canal formation may be induced by adjacent bone spurs or vessels. This case reports the imaging appearance of FR duplication on multiplanar CT.
