case_images: Trismus or facial palsy was not observed (Figure 1).
case_images: Preoperative MRI on T2-weighted image showing high signal intensity admixed with irregular low signal areas in left temporal fossa.

case_images: Magnetic resonance imaging (MRI) revealed a relatively well-demarcated mass in the left temporal muscle, which showed low signal intensity on T1-weighted images and high signal intensity admixed with irregular low signal areas on T2-weighted images (Figure 2).
case_images: Preoperative contrast CT showing ill-demarcated low-density mass with enhancement of the adjacent temporal muscle.

case_images: fig3
case_images: Heterogeneous enhancement of the mass and adjacent temporal muscle was observed between the coronoid process and temporal fossa (Figure 3).
case_images: Intraoperative view demonstrating intramuscular tumor (arrows) with the assistance of zygomatic osteotomy (asterisks).

case_images: A solid nodule was palpated in the temporal muscle and continued beneath the zygomatic arch (Figure 4).
case_images: Microscopic findings of the spindle cell hemangioendothelioma. (a) Low-power view of the lesion showing cavernous blood vessels filled partly or completely with erythrocytes or thrombus admixed with cellular zones (hematoxylin-eosin, original magnification x40). (b) High-power view of juxtaposition of the cavernous and cellular areas illustrating blood-filled dilated vessels lined by flattened endothelial cells and spindle-shaped cellular components. There is no evidence of abnormal mitotic activity or nuclear atypia in spindled cells (hematoxylin-eosin, original magnification x100).

case_images: Abnormal mitotic figures or cellular atypia was not observed (Figures 5(a) and 5(b)).

case_images: The patient was satisfied with the aesthetic result, though a mild depression was observed in the temporal area (Figure 6).
