[The diagnosis and microsurgical treatment of solid cerebellar hemangioreticuloma].

OBJECTIVE

To study the clinical features, neuroimaging presentations, diagnosis and differential diagnosis, and operative warning events of the solid cerebellar hemangioblastoma.

METHODS

The clinical data of 48 patients with solid cerebellar haemangioreticuloma were retrospectively analysed. Preoperative examinations included CT and MRI in all patients, DSA in 20, preoperative embolization of feeding arteries of tumor in 16, a preoperative ventriculoperitoneal shunt was placed in 5 cases. The lesion distribution of 48 patients was as follows: 14 lesions were situated in the left hemisphere of cerebellum with an extent into the cerebellopontine angle in 2 cases, 12 in right hemisphere of cerebellum, 8 in superior vermis, 7 in inferior vermis, 6 in left subtentorium, 1 in left cerebellar tonsil.

RESULTS

The tumors of 48 patients were totally removed. One patient occurred normal perfusion pressure breakthrough during surgery, and gastrointestinal hemorrhage on the second day after operation. Other patients all were intra- and postoperatively uneventful. Except for autoinfusion, no patients transfused heterogenous blood. There were no operative mortality and serious complications in this series.

CONCLUSIONS

The solid cerebellar hemangioblastoma was benign neoplasm. Abiding by properly operative techniques, the optimal results can be obtained.
