case_images: Axial T1-weighted spin-echo imaging (491/11) (TR/TE) performed before radiotherapy demonstrated an isointense tumor in the right orbital space and the right ethmoid sinus (arrow). The right optic nerve was involved by the tumor.

case_images: There was no evidence of lymphoid follicle growth or malignancy, leading to a pathological diagnosis of Kimura's disease after considering the blood test results (fig. 2).
case_images: Dose distribution. One oblique field is shown.

case_images: A single anterior oblique portal was used to avoid radiation exposure of the right lens (fig. 3).
case_images: Eighty-four months after radiotherapy, axial T1-weighted spin-echo imaging (440/150) (TR/TE) demonstrated the disappearance of the right orbital tumor.
