Astroblastoma is a rare glial tumor derived from the astroblast, a type of cell that closely resembles spongioblastoma and astrocytes.[1] Astroblastoma cells are most likely found in the supratentorial region of the brain that houses the cerebrum, an area responsible for all voluntary movements in the body.[2] It also occurs significantly in the frontal lobe, parietal lobe, and temporal lobe, areas where movement, language creation, memory perception, and environmental surroundings are expressed. These tumors can be present in major brain areas not associated with the main cerebral hemispheres, including the cerebellum, optic nerve, cauda equina, hypothalamus, and brain stem.[3]
The most defining physical symptom of astroblastoma, regardless of location, is elevated intracranial pressure, occurring when cerebrospinal fluid in the subarachnoid space exhibits heavy pressure and decreased blood flow, resulting in throbbing headache or nausea for the patient.[2] Despite widespread localization in the brain, astroblastoma is rarely reported in oncological studies, accounting for only 0.45–2.8% of all brain gliomas since its discovery in 1926.[4][5][6] Without a doubt, astroblastoma remains one of the most challenging and problematic tumors to diagnose and treat among all nervous system cancers.
