Ependymoblastoma

Ependymoblastoma (ependymoblastoma; ependymoblast + -oma; synonym: atypical ependymoma, dedifferentiated ependymoma, malignant ependymoma) is a malignant tumor arising from ependymoblasts of the spinal cord and brain. Belongs to the group of ependymomas.

It is characterized by infiltrative growth, frequent relapses and metastasis along the cerebrospinal fluid pathways. Histologically, the tumor consists of small cells with hyperchromic nuclei and contains areas of pseudorosette formation and necrosis.

Ependymoblastoma occurs predominantly in children and is most often localized in the posterior cranial fossa. Clinically manifested by focal neurological symptoms, vomiting, headache.

Diagnosed using MRI and tumor biopsy. Treatment is surgical in combination with radiation and chemotherapy. The prognosis is unfavorable.



Ependymoblastoma: A Rare and Aggressive Tumor of the Central Nervous System

Ependymoblastoma, also known as ependymoma atypical, ependymoma dedifferentiated, or ependymoma malignant, is a rare form of malignant tumor of the central nervous system. It arises from the ependymal epithelium, a layer of cells that lines the ventricles of the brain and the central canal of the spinal cord.

Ependymoblastoma often occurs in young children, but can also develop in adults. The tumor usually forms inside the ventricles of the brain or in the spinal cord. Unlike other ependymal tumors, ependymoblastoma is characterized by rapid and aggressive growth, as well as a tendency to metastasize to other areas of the central nervous system.

The clinical manifestations of ependymoblastoma depend on its location and size. Patients may experience headaches, nausea, vomiting, changes in vision, coordination problems, and other symptoms associated with increased intracranial pressure or compression of surrounding tissues.

The diagnosis of ependymoblastoma is usually made based on a comprehensive approach, including neuroeducation studies such as magnetic resonance imaging (MRI) and computed tomography (CT), tumor biopsy, and analysis of tissue samples.

Treatment for ependymoblastoma usually involves surgical removal of the tumor, supplemented with radiation and chemotherapy if necessary. However, due to the aggressive nature of the tumor and its tendency to recur, the prognosis for patients with ependymoblastoma often remains poor.

In recent years, research has been conducted to develop new and more effective treatments for ependymoblastoma. Some of these include the use of molecular targeted therapies, immunotherapy and gene therapy. However, these approaches are still at the research stage and require further clinical trials.

In conclusion, ependymoblastoma is a rare and aggressive tumor of the central nervous system. Its diagnosis and treatment require a multimodal approach, and despite modern advances in medicine, the prognosis for patients remains difficult.Ependymoblastoma: A Rare and Aggressive Central Nervous System Tumor

Ependymoblastoma, also known as atypical ependymoma, dedifferentiated ependymoma, or malignant ependymoma, is a rare form of malignant tumor that affects the central nervous system. It originates from the ependymal cells, which line the ventricles of the brain and the central canal of the spinal cord.

Ependymoblastoma commonly occurs in young children but can also develop in adults. The tumor typically arises within the brain ventricles or the spinal cord.

The clinical manifestations of ependymoblastoma depend on its location and size. Patients may experience headaches, nausea, vomiting, changes in vision, coordination difficulties, and other symptoms related to increased intracranial pressure or compression of surrounding tissues.

The diagnosis of ependymoblastoma is typically established through a comprehensive approach, including neuroimaging studies such as magnetic resonance imaging (MRI) and computed tomography (CT), tumor biopsy, and analysis of tissue samples.

Treatment of ependymoblastoma usually involves surgical removal of the tumor, supplemented with radiation therapy and chemotherapy when necessary.

Ependymoma and ependymoepithelioma are not unambiguous diagnoses, having different morphological structures. They are distinguished from metastatic lesions, lymphadenitis, or intracranial neoplasms, respectively. Unfortunately, the disease is difficult to diagnose based only on symptoms and instrumental examination methods - CT and MRI are not very informative. For more accurate results, a biopsy of the formation is prescribed, followed by histological examination.

An epithelial tumor arises from the epithelium that supplies the brain with nutrients—encephalocytes. Atypical structures appear in places where brain cells are in direct contact: between the white
