This is a rare benign tumor, most often occurring in children under 12 years. It represents less than 1% of all brain tumors. In children, the most frequent site of this tumor in the lateral ventricles. Plexuspapillome grow slowly inside the ventricles. They  may block the flow of cerebrospinal fluid. This can cause hydrocephalus and increased the intracranial pressure. Papillomas of the choroid plexus are usually congenital neuroectodermal tumors, they make up about 1% of all tumors of the CNS. Most often they are sitting in the lateral ventricles, sometimes they are multiple, often sit in the 3rd ventricle or...

A oligodendroglioma is a bran tumor , which results from cells in the brain form the scaffold for nerve cells. The corresponding cells is called oligodendrocytes . However, the scaffold is not only occur from oligodendrocytes and other cell types (eg. Astrocytes). Overall, it refers to the supporting tissue as Glia . All tumors that arise from this tissue can therefore summarized under the umbrella of term gliomas. The name oligodendroglioma therefore derived from the cell name and the tumor group. Oligodendroglioma: Frequency Oligodendrogliomas represent about ten percent of all gliomas. They occur most likely in middle-aged (between 35 and 50...

A neuroma (Neuron = nerve cell) is a benign, slow-growing brain tumor that occurs mostly in the posterior fossa. The most commonly occur in the Schwann cells of the eighth cranial nerve. This nerve is a twin Cochleovestibular nerve, therefore has two components – the auditory nerve (cochlear nerve) and the balance nerve (vestibular nerve). The acoustic neuroma almost always grows from the vestibular portion of the 8th cranial nerve, resulting in the name often used vestibular schwannoma. Cranial nerves are made of very, very thin fibers that are encased by a sheath of connective tissue. This case is made...

The meningioma is generally a slow-growing, benign brain tumor (benign cancer) emanating from the meninges of the central nervous system (CNS). Therefore, the meningioma is derived from the medical term “meninges”. Mostly the dura mater adherent bengin tumors of adulthood that arise from the lining cells of the pia mater. Since Meningiomas are usually benign and grow slowly, sufferers  develop only few symptoms often after years. The meningioma is therefore often an incidentally diagnose, which is noticeable in the context of other studies. Under the microscope, different meningioma types can be distinguished. For the forecast tumor classification ( “grading”) is...

A medulloblastoma is a (WHO grade IV ) malignant tumor (brain cancer) which especially occurs in childhood. The tumor develops in the area of the back of the head from the cerebellum and grows into the surrounding tissue, such as in an adjacent ventricle, also known as the fourth ventricle . Ventricles are cavities in the brain , which are filled with liquor. From there, the medulloblastoma can spread quickly in the surrounding healthy tissue, often in the so called brain stem. Often the brainstem is affected by medulloblastoma. Metastases form primarily at the points that are in contact with...

Cerebral Lymphoma Cerebral lymphoma (Lymphoma n the brain) is a type of bran cancer. As degenerate cells of the immune system  in brain are called lymphoma. Specifically, it is in the lymphocytes, which belong to the white blood cells. These form a tumor. A lymphoma in the brain occurs either within the brain ( primary ) or external ( secondary ) from degenerated lymphocytes. These lymphoid cells belong to the  white blood cells (leukocytes) and are actually part of the body’s defense. As a rule, lymphoma in the brain include in the group of malignant  non-Hodgkin’s lymphomas . Cerebral lymphomas are...

The meningioma is therefore often an incidentally diagnose, which is noticeable in the context of other studies. Under the microscope, different meningioma types can be distinguished. For the forecast tumor classification ( “grading”) is of importance: More...
