On Diagnosis And Microsurgical Treatment For Posterior Cranial Fossa Hemangioblastoma

Objective: To discuss the characteristics of magnetic resonance imaging(MRI) and surgical treatment for posterior cranial fossa hemangioblastoma(HB), and to improve the diagnosis and microsurgical treatment level for the disease. Methods: We retrospectively analyzed 43 cases that treated by microsurgical resection of craniotomy and pathology of posterior cranial fossa hemangioblastoma in our department from 2010 January to 2013 December. Results: Total resection was obtained in 37 cases of cystic nodule hemangioblastoma, 4 solid hemangioblastoma and 1 solid-cystic hemangioblastoma, while the lesion was not removed in one case of multiple hemangioblastoma close to the medulla. One week after operation, 40 patients’ neurological symptoms of headache, dizziness, nausea or vomiting were relieved. Walking instability remainded as preoperation in one case. One case of hydrocephalus was given a secondary lateral ventricle puncture three days after the first operation and then removed the ventricular drainage tube seven days after the second operation, and recovered two weeks later。one case of brain stem involvment was given a secondary operation because of hemorrhage in operation area and was dead one day after surgery.40 patients were followed up for 3 months-1 year after surgery: GOS score were 5 in 38 cases( recovery to nomal) and 4 in 1 case( walking instability remained).Recurrence happened in 1 case 6 months after operation, receiving a secondary surgery 15 months later. Conclusion: MRI is the main method of preoperative diagnosis and differential diagnosis for posterior cranial fossa hemangioblastoma. Early microsurgical operation resection is effective and safe to treat the posterior cranial fossa hemangioblastoma.
