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:
General imaging differential considerations include: 1  medulloblastoma similar demographic, especially if around the 4th ventricle. arises from vermis. 2  subependymoma tends to occur in older individuals. 3  choroid plexus papilloma in children usually in the trigone of the lateral ventricles. in adults usually in the fourth ventricle (i.e opposite to ependymoma) more vividly and homogeneously enhancing. lacks adjacent parenchymal oedema. NB choroid plexus carcinoma can be heterogeneous and invade brain.
