Abstract:
Objective To analyze the disease spectrum and clinicopathological characteristics of central nervous system(CNS)diseases diagnosed based on pathological findings in Tibet. Methods We collected the data of all the cases with CNS lesions in Tibet Autonomous Region People's Hospital from January 2013 to December 2020.The clinicopathological features were analyzed via light microscopy,immunohistochemical staining,and special staining. Results A total of 383 CNS cases confirmed by pathological diagnosis were enrolled in this study,with a male-to-female ratio of 188∶195 and an average age of(40.03±17.39)years(0-74 years).Among them,127(33.2%)cases had non-neoplastic diseases,with a male-to-female ratio of 82∶45 and an average age of(31.99±19.29)years;256(66.8%)cases had neoplastic diseases,with a male-to-female ratio of 106∶150 and an average age of(44.01±14.87)years.The main non-neoplastic diseases were nervous system infectious diseases,cerebral vascular diseases,meningocele,cerebral cyst,and brain trauma.Among the infectious diseases,brain abscess,granulomatous inflammation,cysticercosis,and hydatidosis were common.The main neoplastic diseases included meningioma,pituitary adenoma,neuroepithelial tumor,schwannoma,metastatic tumor,and hemangioblastoma.The meningioma cases consisted of 95.4%(103/108)cases of grade Ⅰ,3.7%(4/108)cases of grade Ⅱ,and only 1(1/108,0.9%)case of grade Ⅲ.Among the neuroepithelial tumor cases,the top three were glioblastoma,grade Ⅲ diffuse glioma,and ependymoma. Conclusions There are diverse CNS diseases confirmed by pathological diagnosis in Tibet,among which non-neoplastic diseases account for 1/3 of all the cases.Infectious and vascular diseases are the most common non-neoplastic diseases in Tibet,and tuberculosis and parasitic infections are relatively common.The types and proportion of brain tumors in Tibet are different from those in other regions of China,and meningioma is the most common in Tibet,with higher proportion than neuroepithelial tumor.
