Epithelioid Hemangioendothelioma of the Mastoid: Resection for Recurrence and Adjuvant Radiation with 8-Year Followup
Figure 1
(a) Unenhanced computed tomography scan with bony windowing demonstrates an osteolytic expansile mass within the left mastoid. (b) Gadolinium enhanced axial T1 weighted MRI demonstrates a heterogeneously enhancing lesion within the left mastoid region with mass effect on the cerebellar hemisphere. (c) Gadolinium enhanced coronal T1 weighted MRI demonstrates an enhancing lesion within the left mastoid region extending to the occipital condyle. Postoperative gadolinium enhanced T1 (d) axial and (e) coronal MRI demonstrates a complete resection of the previously identified mastoid mass.
