2A00/C69-C72 Primary neoplasms of brain



Primary neoplasms of the brain are abnormal growths of cells that originate within the brain itself. They can be malignant or benign and can be caused by genetic mutations, environmental exposures, or a combination of both.


The diagnosis of primary neoplasms of the brain is made using imaging studies such as CT, MRI, or PET scans. These imaging studies help to identify the tumor and its location. Other tests may be used to confirm the diagnosis such as biopsy, lumbar puncture, or electroencephalogram.

Differential diagnosis

Primary neoplasms of the brain can be mistaken for other conditions, such as brain abscesses, vascular malformations, or other causes of brain swelling. In order to accurately diagnose primary neoplasms of the brain, it is important to differentiate them from other conditions.


Treatment of primary neoplasms of the brain usually involves a combination of surgery, radiation therapy, and chemotherapy. Surgery may be used to remove the tumor, while radiation therapy and chemotherapy can be used to destroy any remaining cancer cells.


The prognosis for primary neoplasms of the brain depends on a number of factors such as the type and size of the tumor, the patient’s age and overall health, and the treatment received. In general, the prognosis is better for benign tumors than for malignant tumors.
