OLIGODENDROGLIOMA BRAIN TUMOR- GRADE III
Oliogodendroglioma (OD) Brain Tumor is a rare, slow growing tumor that initially consists of oligodendrocytes, which are, cells that cover and protect nerve cells in the brain and spinal cord. Tumors that are located in the frontal lobe may cause weakness on one side of the body, personality or behavior changes, and difficulty with short- term memory. Tumors occurring in the temporal lobe of the brain may cause seizures or language problems. These tumors rarely metastasize outside of the nervous system. The exact cause of OD brain tumors is unknown.
DIAGNOSTIC TESTING, PHYSICAL FINDINGS, AND ICD-9-CM CODING
Diagnostic testing: Oligodendrogliomas are diagnosed using CT or MRI scans. Brain biopsy is definitive.
Physical findings: People with these tumors may present with complaints of headaches, seizures, increased intracranial pressure, and neurological deficits such as, visual loss, motor weakness, and cognitive decline.
ICD-9: 191.X Depends on the location of the tumor.
ONSET AND PROGRESSION
Oligodendrogliomas can occur at any age, but are commonly diagnosed in young and middle age adults with a median age between 40 -50 years of age. This tumor may occasionally be found in children. Because low-grade tumors are slow growing, they are often present for years before they are diagnosed; however, higher grade tumors are likely to grow more quickly.
The treatment of OD tumors depends on the size, location, and grade of tumor. Biopsy is generally performed to confirm the diagnosis and to grade the tumor. Recurrent low grade oliogodendrogliomas may be treated with a combination of surgical resection, chemotherapy and radiation.
