Cerebellar hemangioblastoma is common, also known as angioretinoblastoma, is a benign tumor, most of which are solitary; a few are multiple tumors, which can be combined with retinal and spinal cord hemangioblastoma, as well as tumors of the kidney and other organs. The main manifestations are headache, dizziness, nausea and vomiting, and unsteadiness in walking. The main examination: cranial MRI scan and enhancement Treatment: Surgical resection is the first choice. For multiple small tumors, gamma knife radiotherapy can be used. Follow-up: Since tumors can occur multiple times at the same time or sequentially, the enhancement MRI should be reviewed periodically after surgery. Surgery is relatively easy if the tumor is not close to the brainstem. Large substantial hemangioblastoma is relatively rare. Due to the abnormally rich blood supply of substantial hemangioblastoma, the risk of surgery for large substantial hemangioblastoma is very high, and the risk is even higher if the tumor is close to or compressing the brainstem, which is extremely harmful to the patient, and the surgery is very prone to serious complications and even death by intraoperative hemorrhage, so if it can be detected and treated early, the risk will be greatly reduced. The following is a case of a patient with hemangioblastoma who had been operated twice in a foreign hospital. The patient’s tumor was cystic at the beginning and was relatively easy to be removed surgically, but it was not reviewed regularly after surgery. After reoperation, the right cerebellar hemangioblastoma was completely excised successfully and recovered well after surgery. The small-sized hemangioblastoma tumor on the left side required further radiotherapy treatment and close review. The following case of dorsal brainstem hemangioblastoma was compared with MRI enhancement before and after surgery, and the tumor was completely resected.
