Histopathological diagnosis based on the specimen obtained from the shaving procedure was consistent with FD. ( Fig. 1 ) However, the patient demonstrated rapid enlargement of the zygomatic bone at the 3-month postoperative follow-up.
(
A
) Computed tomography (CT) scanning shows a 2.4 x 1.8 x 1.5cm-sized bony expansile lesion with predominantly homogeneous ground glass appearance and focal radiolucent area in the left zygoma. (
B
) CT scanning revealed rapid growth of the lesion, which was well-circumscribed and involved the left zygomaticomaxillary area.
