Patient: My mother is often diagnosed with an auditory neuroma, large at 2 x 3 cm, by MRI in a familiar hospital. Is it better to treat this tumor with gamma knife or with scalpel. Thank you. Nanjing Brain Hospital neurosurgery Zou Yuanjie: the information you provide is incomplete, I can not give specific advice, please add the following information: cranial MR and related clinical symptoms: the presence of hearing loss on the affected side and tinnitus, etc. Whether to choose surgical treatment requires the doctor to assess the patient’s surgical tolerance, the patient’s awareness of the complications of surgery, it is best to operate in a tertiary hospital. Gamma knife is mostly a palliative treatment. Patient: Hello, Dr. Zou, MR diagnostic report is as follows: cranial MRI scan plus enhancement image performance: brain midline structure in the center, the supratentorial ventricular system is slightly larger, brain sulcus, brain fissure and brain pool without widening, the left pontocerebellar angle can be seen as a round-like long T1 long T2 abnormal soft tissue mass, the maximum diameter is 3cm, the left auditory nerve thickening, pontocerebellar, four ventricles compression, four ventricles deformation, after enhancement can be seen pontocerebellar The abnormal signal of the cerebellar horn can be significantly enhanced, and the thickened auditory nerve on the left side can also be enhanced. Impression: left pontocerebellar horn occupying lesion, consider auditory neuroma. And the patient’s left ear hearing without tinnitus, this tumor is surgical knife or with gamma knife? What kind of knife is better? Thank you, Zou Yuanjie, Department of Neurosurgery, Nanjing Brain Hospital: According to the MRI report, the tumor in the left pontocerebellar horn is accompanied by mild hydrocephalus, and the occupying effect exists. If the patient has no serious organic disease, surgery can be considered. The physician mainly looks at the film to evaluate the surgery, not the report. Gamma knife treatment is radiotherapy, not surgery.
