Tumor Subtentorial

A subtentorial tumor (lat. Subtentorialis) is a tumor that develops in the subtentorial space, between the brain and meninges. It can be either benign or malignant, and its causes vary.

The subtentorial space is a narrow space between the brain and cerebrospinal fluid that is located at the back of the skull. It is surrounded by three membranes: the dura mater, the arachnoid membrane and the arachnoid membrane. This space contains important structures such as the cerebellum, brain stem and spinal cord.

Tumors of the subtentorial space can arise from various tissues, including glial cells, neuroglia, vascular tumors, and others. They may present with a variety of symptoms such as headache, nausea, vomiting, seizures, visual and hearing impairment, and other neurological disorders.

Treatment of a subtentorial tumor depends on its type, size and location. In some cases, surgical removal of the tumor may be required, and in others, radiation therapy or chemotherapy. The prognosis for patients with a subtentorial tumor may vary depending on the type of tumor and its size.

Diencephalon

The intermediate section of the brain is located between the posterior and middle sections, but also has important connections with the cerebellum, hypothalamus, reticular formation and partly with the spinal cord. It is a continuation of the medulla oblongata; the boundaries of the diencephalon are responsible for a clear boundary between the two sections. It includes the third ventricle, which is connected to the anterior and lateral ventricles through the aqueductal foramina of the 3rd pair of cranial nerves, as well as the cerebral peduncles, which form the cerebral bridge.

This area is essential for conducting and regulating vital brain functions such as breathing, cardiovascular and excretory systems. The cerebral cortex is responsible for higher brain functions such as consciousness, information perception, planning, reactions and interpretation of signals, both conscious and unconscious. The medulla oblongata provides vital functions including swallowing, breathing, blood pressure and the heart. The cerebellum is responsible for the coordination of movements and
