Figure 1. Sagittal enhanced MRI before and after surgery. The red arrow indicates the intraorbital tumor, the yellow arrow indicates the intracranial tumor, and the white arrow indicates the residual cavity after total tumor resection. Figure 2. Horizontal enhanced MRI before and after surgery. The yellow arrow indicates the tumor, and the white arrow indicates the residual cavity after total tumor resection. Postoperatively, the patient had normal vision and normal eye movement. Cranio-orbital communicating tumor is a complex tumor at the base of the skull. Because the tumor involves the orbit and the skull, most ophthalmologists in provincial hospitals nationwide cannot handle this type of tumor, which is usually operated by neurosurgeons, and only a few neurosurgeons are competent to operate on this part of the tumor.
