A brain tumor is an intracranial solid neoplasm, a tumor (defined as an abnormal growth of cells) within the brain or the central spinal canal. Some tumors are brain cancers. Brain tumors may also spread from cancers primarily located in other organs (metastatic tumors) [1]. Brain tumors are the second leading cause of cancer-related deaths in children under age 20. They are the second leading ...

The Image-based modeling of tumor growth combines methods from cancer simulation and medical imaging. In this context, we present a novel approach to adapt a healthy brain atlas to MR images of tumor patients. In order to establish the correspondence among a healthy atlas and a pathologic patient image, tumor growth modeling in combination with registration algorithms is employed. In a first st...

objective: to report involvement of the central nervous system (cns) following epithelial ovarian cancer is rare. advances in management of ovarian cancer by use of primary surgery including abdominal hysterectomy, bilateral salpingo'oophorectomy should attain as complete a cytoreduction as possible and effective platinum-based chemotherapy have prolonged survival. case report: we present a cas...

Background and Aim: Smoking has been extensively investigated in oncology, controversial associations with brain tumor incidence have reported. Caspase-3 matrix metalloproteinases (MMPs) belong to an important cascade vasculogenesis. We aim study the smoking impact on these signaling molecules nontumoral rat tissue. Methods Materials/Patients: A total of 60 Wistar rats were divided into two gro...

Adenoid cystic carcinoma is a rare malignant neoplasm of the salivary gland. Salivary gland neoplasms constitute 3% cancers all sites, which, 10–15% are malignant. Though adenoid most common tumor submandibular, sublingual and minor glands, it accounts for only 15% parotid cancers. They generally slow-growing spread relentlessly to adjacent structures. Hematogenous more than lymphatic spread, s...

Background: Virchow-Robin (VR) spaces are the fluid-filled perivascular spaces adjacent the brain vessels. The signal intensities of the VR spaces are very similar to those of cerebrospinal fluid (CSF). VR spaces should be distinguished various pathologic conditions, including lacunar infarctions, cystic periventricular leukomalacia, cryptococcosis, cystic neoplasms and neuroepithelial cysts. C...

Choroid plexus carcinoma is an uncommon neoplasm of the central nervous system most commonly found in the pediatric population. It is associated with a dismal prognosis, especially if incompletely resected. Accurate histopathologic diagnosis is imperative, and this neoplasm should always be included in the differential diagnosis of a papillary intraventricular tumor. Histopathologic features in...

A case is reported of an intracranial neoplasm of mixed mesenchymal and neuroepithelial (glial) origin occurring in the parieto-parasagittal region of the brain of a 19 year old man. A meningioma with liposarcomatous and psammomatous components comprised the mesenchymal part of the combined tumour. The neuroepithelial portion was composed of mixed ependymoma and astrocytoma. The combined neopla...
