Introduction Brain cysts are delimited cavities in brain tissue, which can be either empty or filled with fluid. Sometimes they are additionally divided into several small chambers. Brain cysts are generally benign and, as long as they do not cause any symptoms, do not always need to be treated. In this case they are often … Brain cysts
Cysticercosis Cysticercosis is a parasitic disease caused by infection with the tapeworms Taenia saginata and Taenia solium. The tapeworms use humans only as intermediate hosts and not as final hosts, which is why they store their eggs in different tissues. This results in the formation of the characteristic cysts in which the new tapeworms develop … Cysticercosis | Brain cysts
Therapy As long as the brain cysts do not cause any symptoms, they do not have to be treated in every case. Observation and regular control is sufficient at first. This does not apply to brain cysts that have been caused by a parasitic infection. These are either surgically removed or additionally treated with medication. … Therapy | Brain cysts
Brain cysts in children Since strokes or parasites (at least in Germany), which can lead to the formation of cysts in adults, are generally less common in children, most brain cysts are congenital in children. These are hollow spaces that have been created during brain development in addition to the normal cerebral ventricle system and … Brain cysts in children | Brain cysts
Congenital brain cysts Since congenital cysts in the brain often occur without specific symptoms, they are often diagnosed as a random finding even in adulthood. Many people live with these brain cysts without ever having problems with them. However, if the cyst is known, it should be checked regularly to notice a fast growth in … Congenital brain cysts | Brain cysts
History The course of a brain tumor depends primarily on whether it is a benign or malignant tumor. Slow-growing benign tumors cause symptoms at a very late stage and can often be removed before they become malignant. By contrast, malignant, aggressive tumors become symptomatic much earlier. Depending on which symptoms occur, the disease progresses better … History | Signs of a brain tumor
Proliferations of the brain or meninges are collectively referred to as brain tumors. The tumor can be either good or malignant. Benign tumors in the brain grow rather slowly and usually remain clearly contoured, i.e. they can be easily distinguished and recognized from the surrounding brain tissue. In contrast, malignant tumors are characterized by rapid … Signs of a brain tumor
Introduction Medulloblastoma is a malignant, embryonic brain tumor of the cerebellum, which is classified as the most severe grade according to the WHO classification of tumors of the central nervous system, i.e. grade IV. Despite its degree, it has a fairly good prognosis. With 30%, medulloblastoma is the most common brain tumor in childhood and … Medulloblastoma
Appearance The medulloblastoma is usually a soft tumor with a blurred, soft surface and a gray-white cut, but can occasionally be sharply defined and rough. Larger tumors have central areas where actually active cells die (necroses). Microscopically, the classical medulloblastoma consists of densely packed cells with round to oval, strongly stainable (hyperchromatic) nuclei, surrounded by … Appearance | Medulloblastoma
Symptoms The most common initial symptoms are headaches, nausea and vomiting, which are caused by the increased pressure in the skull (intracranial) and the disturbance of the cerebral fluid flow (cerebrospinal fluid circulation). In addition, the obstruction of the cerebrospinal fluid flow leads on both sides to swelling (edema) of the exit point of the … Symptoms | Medulloblastoma
Differential diagnosis Medulloblastomas have to be differentiated from similar small cell embryonic tumors such as neuroblastomas, ependymoblastomas, pinealomas and tumors of the lymphatic tissue (lymphomas). Therapy The therapy consists of the most radical possible surgical removal of the tumor and the subsequent high-dose irradiation with 40 Gray with direct irradiation of the posterior fossa and … Differential diagnosis | Medulloblastoma
Summary Medulloblastomas are rapidly growing, malignant tumors of childhood and adolescence that originate from the cerebellar worm and can metastasize into the cerebrospinal fluid. The symptoms are vomiting, ataxia with a tendency to fall and congestive papillae with loss of visual acuity. For diagnosis, a CT and an MRT are performed. Therapy consists of surgical … Summary | Medulloblastoma
