• Angioglioma — A rare and complex brain tumorous formation of a mixed nature, structurally composed of a proliferative glial component (glioma) and a dense, rich network of newly formed blood vessels (angiomatous component). This well-defined oncological lesion, localized predominantly within the central nervous system, often poses difficulties in differential histopathological diagnosis and requires strict imaging monitoring due to the risk of intracranial hemorrhage or perifocal edema.
• Astroblastoma — A rare neuroepithelial brain tumor of glial origin, characterized by the abnormal proliferation of astroblasts (embryonic precursor cells of astrocytes). This type of neoplasm develops predominantly in the cerebral hemispheres of children and young adults, displaying on histological examination a characteristic arrangement of tumor cells in the form of perivascular rosettes or pseudorosettes, with cytoplasmic extensions anchored to the vessel walls.
• Astrocytoma — A brain tumor or malignancy of the central nervous system developed through the abnormal proliferation of astrocytes (star-shaped glial cells). This neoplasm represents the most common type of glioma and can vary from slow-growing, benign forms (such as grade I pilocytic astrocytoma) to highly aggressive, infiltrative forms (such as grade IV glioblastoma). Diagnosis is established via magnetic resonance imaging and histopathological examination.
