Benign supratentorial neoplasms refer to non-cancerous abnormal growths or tumors that develop within the supratentorial region of the brain. The brain can be broadly divided into two main regions: supratentorial (above the tentorium) and infratentorial (below the tentorium). The supratentorial region encompasses the cerebral hemispheres, which control various cognitive and motor functions of the body.
In the context of brain tumors, the term "benign" indicates that these neoplasms are not cancerous and do not possess the ability to invade surrounding tissues or metastasize to distant parts of the body. Despite being non-malignant, benign supratentorial neoplasms can still cause symptoms and complications depending on their size, location, and impact on nearby structures within the brain.
These neoplasms can originate from different types of brain cells, such as glial cells, meninges, or neurons. Some commonly found benign supratentorial neoplasms include meningioma, a tumor arising from the meninges (the protective covering of the brain), and glioma, which develops from glial cells. Other types include pituitary adenoma, hemangioma, and craniopharyngioma.
Diagnosis of benign supratentorial neoplasms usually involves a combination of medical history assessment, neurological examination, imaging techniques like MRI or CT scans, and sometimes biopsy to confirm the nature of the tumor. Management options often depend on specific characteristics of the tumor and the individual patient, but treatments may include surgical resection, radiation therapy, chemotherapy, or a combination of these modalities.
Overall, the prognosis for benign supratentorial neoplasms is
