Chondromyxoid fibroma of the temporal bone: A case report and review of the literature

Figure 1 Axial computed tomography scan demonstrates a well-defined mass with a sclerotic rim and a scalloped margin originating from the mastoid portion of the temporal bone. A: The ipsilateral hypoglossal canal (arrow head) and the jugular foramen (arrow) were eroded by the mass. The contralateral hypoglossal canal (blank arrow head) and the jugular foramen (blank arrow) were normal; B: The left mastoid portion of the facial nerve canal was invaded by the tumour (blank arrow). Intratumoral calcification was noted in the tumour (arrow head).
