case_images: Postcontrast computed tomography (CT) findings. The right parotid gland tumor in scans obtained in our hospital (b) is smaller than that in scans obtained in our affiliated hospital (a).

case_images: C-reactive protein (CRP) of 0.18 mg/dL. Computed tomography (CT) revealed an enhanced irregularly shaped mass in the right parotid gland (Figure 1(a)). CT showed that the tumor had become smaller than at the time of the previous scan in our affiliated hospital (Figure 1(b)).
case_images: MR imaging findings. (a) A T1-weighted image showing the tumor to have lower intensity than that of the native parotid tissue. (b) A T2-weighted image showing the tumor to have an intermediate signal intensity and partial hyperintensity.

case_images: T1-weighted SE MR imaging of the mass showed lower intensity than that of the native parotid tissue (Figure 2(a)). T2-weighted SE MR imaging also showed intermediate signal intensity and partial hyperintensity (Figure 2(b)).
case_images: Intraoperative view of the facial nerve. The buccal branch and marginal mandibular branch can be seen to be compressed by the tumor.

case_images: The buccal and marginal mandibular branches of facial nerve were pinched by the tumor (Figure 3).
case_images: Frozen section of the neoplasm. Clear cells can be seen to form a clear boundary between the normal parotid gland tissues (haematoxylin-eosin, x100).

case_images: Histopathological examination showed the tumor contained clear cells, which formed a clear boundary between the normal parotid gland tissues (Figure 4).
