case_images: A 71-year-old male patient presented to a hospital other than ours in January 2022, complaining of a one-month history of right eye proptosis, visual impairment, and diplopia ( Figure 1 ).
case_images: Diagnostic image. Group A (A1, A2, and A3) consists of preoperative MRI images. Group B (B1, B2, and B3) displays MRI images taken before TOMO treatment. Group C (C1, C2, and C3) shows MRI images taken before the Gamma Knife treatment, while group D (D1, D2, and D3) displays MRI images taken after the Gamma Knife treatment. Within each group, 1, 2, and 3 correspond to the transverse, coronal, and sagittal planes, respectively, showing the maximum level of the lesion. The arrow indicates the location of the lesion.

case_images: Magnetic resonance imaging (MRI) revealed an irregularly shaped mass measuring 3.5x3.4cm within the intraconal and extraconal spaces of the right eye orbit ( Figures 2A1-3 ). T1-weighted images and slightly hyperintense on T2-weighted images, with uniform enhancement, a long axis of approximately 15mm, smooth edges, and a broad base connected to the adjacent orbital wall ( Figures 2B1-3 ). The local abnormal signal in the anterior chamber was slightly increased compared with the previous month. After nearly 5 weeks of radiotherapy, a follow-up MRI of the orbital cavity showed no change in the size of the recurrent lesion in the right orbital cavity ( Figures 2C1-3 ). An MRI follow-up on August 2, 2022, showed no significant changes compared with the previous one ( Figures 2D1-3 ).

On May 13, 2022, Gamma Knife treatment was performed with 50% prescription dose 13.5Gy/3f, once every other day, which was completed within one week ( Figure 3 ). An MRI follow-up on August 2, 2022, showed no significant changes compared with the previous one ( Figures 2D1-3 ).
