"current medical history"patients about 1 year ago appeared dizziness with walking instability, gradually accompanied by headache and water cough, no obvious visual rotationPatients in the course of the disease without vomiting, no limb convulsions and incontinence, no obvious consciousness disorderthediscussionComment: right cerebellum cyst real occupancy lesions, the real part of the density, after strengthening continued to strengthen obvious, the edge see multiple vascular shadow, the fourth ventricle and brain stem pressure, the ventricle expansion, adjacent to the thinning of the pillow boneCerebellum hemangioblastoma is highly likely, without the exception of meningioma with cystic changeResultsWhat you see during the operation: Most of the tumors seen in the surgery are located outside the epidural, the blood supply is rich, tough, gray-whitepathological diagnosis: (right cerebellum epidural) transitional meningioma (the above-skin cell type, a small number of fibrotypes, WHOI.level) "case small knot" meningioma is also known as cobweb endometheoma, the tissue occurrence of meningioma may come from embryo residue or cobweb fluff Meningahems is divided into 15 subtypes, transitional (hybrid) meningioma is one of the more common cases of subtype, belongs to WHOI-grade tumors, with endothelial cell type and fibrous transition characteristics The essential components of histological synod are meninges, fibroblasts, transitional cells, blood vessels and sand particles often single hair, rich blood supply, expansion growth-based, common in 40 to 60 years old middle-aged and elderly imaging performance: transitional meningioma can be circular, oval or leaf-like, even or uneven density, clear boundaries, occasionally visible meninges tail or false envelope signs, enhanced scanning most of the strengthening significant, some cases of tumor sonactually see no reinforced low-density degenerative necrosis area or point, flaky calcification, tumor week or edema, and a few other cases of invasion of adjacent skulls identification diagnosis: 1 glioma: mostly located on the screen, density is uneven, boundary irregular 2 Angiomatoma: a rare intracranial malignant tumor, an external lump of the brain, leaf-like or cauliflower-like, enhanced scanning and strengthening obvious, adjacent to the bone visible bone-soluble destruction 3 Angioblastoma: benign tumor, mostly located under the curtain, typically manifested as large sac small nodules, tumor week generally no edema source: the image
