There is a well-defined, round fat attenuating (HU: -100), non-enhancing mass lesion in the right medial angular extraconal location measuring approximately 2.1x 1.8 x 1.6 cm. No evidence of any calcification in the lesion. No adjacent infiltrative or inflammatory changes. No extension inside the orbital cavity. No intracranial extension. No adjacent bony destruction or suspicious periosteal reaction.
