Answer- A Dermoid cyst
Dermoid cysts are benign congenital choristomas of the orbit that originate from fetal bone suture lines during development, most commonly the frontozygomatic suture.
Dermoid cysts can also erode the orbital plate of the frontal bone to become attached to dura and for this reason it is important to image the area by computed tomography (CT) before excision.
