intracranial gliosis has no typical clinical signals or imaging characteristics. therefore, it can be easily misdiagnosed as neoplasm. hereby, we report a unique case of gliosis that grew outward from the surface of the brain. mri depicted its signal and enhancement pattern similar to the cerebral gray matter. the diagnosis was confirmed by pathology and immunohistochemistry. although it was di...

Serous cystic neoplasms of the pancreas are rare exocrine pancreatic neoplasms, most of which are benign and do not communicate with the pancreatic duct. Pancreatic intraepithelial neoplasm (PanIN) is considered a precursor of ductal adenocarcinoma that is microscopically recognized in pancreatic ducts. A 67-year-old Japanese woman presented with a 10-mm multilocular cystic lesion at the pancre...

Most ovarian neoplasms are benign, epithelial types are commonest. There is no regular screening test for detecting malignant ovarian neoplasm, most patients remain asymptomatic until late stages. About 80% of malignant ovarian neoplasm present in stage 3 and 4 with 15% 5 year survival rate. To find out frequency of different types of ovarian neoplasm among women aged 15-60 years and correlates...
