Broken ribs can be extremely painful. Often, the pain from a rib fracture is worse when taking a deep breath. Severe broken ribs require evaluation and treatment at a hospital; usually these cause so much pain that a person naturally seeks medical attention. The key to recovery from broken ribs is pain control.
Brain tumors are classified according to histology, but tumor location and extent of spread are important factors that affect treatment and prognosis. Ependymomas arise from ependymal cells that line the ventricles and passageways in the brain and the center of the spinal cord. Ependymal cells produce cerebrospinal fluid (CSF). These tumors are classified as supratentorial or infratentorial. In children, most ependymomas are infratentorial tumors that arise in or around the fourth ventricle. According to the 2016 revision to the World Health Organization (WHO) classification of tumors of the central nervous system, ependymal tumors are classified into the following five main subtypes:
Ependymoma. An ependymoma is a type of brain tumor that arises from cells that line the ventricles of the brain and the central canal of the spinal cord. The ventricles are fluid filled spaces inside the brain.There are four ventricles, two lateral ventricles, the 3rd ventricle and the 4th ventricle.An ependymoma can arise in any of these areas since all of them are lined with ependymal cells (the name for the cells lining the venricles).hey can occur in any of the ventricles or in the spinal cord. Occasionally, after originating in one place, they spread to other areas through the cerebrospinal fluid, the liquid that is inside and surrounding the brain and spinal cord. Both adults and children can develop an ependymoma.
