Young female, intermittent headache, dizziness in January, please diagnose!

Neurosurgery"Basic Information"patients, female, 27-year-old"main complaint"intermittent headache, dizziness in January"current medical history"patients intermittent headache for many years, before admission to the hospital in January appeared dizziness, nearly 10 days gradually aggravated, with walking instability for more than 3 days( Image )the diagnosis of the problem?thecomments: the right cerebellum hemispheric visible cysts, the real part is slightly longer T1 slightly longer T2 signal, the cyst part is significantly longer T1 significantly long T2 signal, enhance the scanning lesions real part significantly strengthened, the cerebellum under the cerebellum, the four ventricles obviously under pressure, the upper ventricle expansionConsideration: 1myelin cell tumor; 2hair cell atomtumor; 3Hemangioblastomaresults)pathological diagnosis: hair cell atomtumor"case summary"hair cell astrocyte tumor is a rare benign tumor, is a Grade I astrocyte tumor4% to 5% of intracranial gliomasThe incidence ratio is equal for men and women, can occur at any age, more children and adolescents, the peak of the incidence of 3 to 7 years oldClinical symptoms are increased intracranial pressure, headache, vomiting, etcDepending on the tumor location of different local symptoms, located in the cerebellum hemisphere can appear with side limb co-operation disorder, holding unstable, muscle tone and low tendon reflexes and other manifestationsTumors are good in the cerebellum, with the cerebellum, followed by the cerebellum hemisphere, which can also occur on the screenAccording to its cystic degree, can be divided into three types: 1cyst type: lesions are cystic, no wall nodules or solid lumps; 2cyst nodules: cysts mainly, accompanied by wall nodules; 3lumps: lesions to the real part, accompanied or not accompanied by cystsCT performance: flat sweep: tumor cysty part showed significantly low density, tumor cyst wall, wall nodules and real parts of the equivalent density or slightly lower densityThe tumor boundary is clear, and there is no edema for more than one weekAfter the enhancement of the tumor sac wall is not strengthened or mildly strengthened, wall nodules and the actual part is significantly strengthened, the cystic part is not strengthenedTumor bleeding and calcification are rare MRI performance: The cystytic part of the tumor shows a significantly long T1 signal on T1WI, and most of it is a long T2 high signal on T2WI Tumor real part, cystic wall and wall nodules T1WI are equivalent or slightly lower signal, T2WI is slightly higher signal After the enhancement of the tumor sac wall is not strengthened or mildly strengthened, wall nodules and the actual part is obviously strengthened, the cystic part is not strengthened differential diagnosis: hemangioblastoma: good in the cerebellum hemisphere, squash small, no cystic wall strengthening Brain abscess: the wall is smoother, thick and uniform, generally no wall knots source: the image
