title: Reconstructive myofascial skull-base flaps: normal appearance on CT and MR imaging studies.
abstract: On imaging studies, the tendon and fractured coronoid process are clues to the presence of a temporalis myofascial flap. A large, bulky muscle and subcutaneous fat are characteristic of a free flap with microvascular anastomosis. The enhancing, thin, curvilinear pericranial flap bridges an osseous defect of the anterior skull base. Familiarity with these features is essential to avoid misdiagnosis of normal flap as tumor and to identify tumor recurrence.
