Astrocytoma Treatment in Orange County by Dr. Robert Louis

Astrocytoma Treatment in Orange County by Dr. Robert LouisAstrocytoma tumors grow from the star-shaped glial cells, astrocytes, which play a fundemental part in supporting the brain. Astrocytomas are typically located in the cerebrum but can occur anywhere in the brain and occasionally in the spinal cord. Astrocytomas are seldomly found outside the brain or spinal cord. Astrocyotomas may either be benign or malignant.

Anyone may develop astrocytomas but are more common in adults and slightly more common in men. Astrocytomas make up a majority of brain tumors found in children.

Currently, there are several theories behind the causes of astrocytomas which include exposure to chemicals and genetics. However, as with all tumors, the exact cause is unknown.

Because there are different types of astrocytomas with varying grades, symtoms are also different. Typically, these are the most common symtoms experienced:

  • Headaches and dizziness
  • Nausea and vomiting
  • Seizures
  • Loss of appetite
  • Confusion
  • Behavior and personality changes
  • Difficulty in motor skills
  • Enlarged skulls in infants

Diagnosis can be determined by reviewing medical histories and performing physical and neurological examinations. Blood, urine, vision and hearing may be tested by Dr. Louis. Brain imaging procedures such as CT scans and MRI scans are used by Dr. Louis to determine the size and location of an astrocytoma.

Magnetic resonance imaging (MRI): An MRI uses magnetic fields to produce detailed images of the body. A special dye called a contrast medium is injected into a patient’s vein before the scan to create a clearer picture.

Stereotactic neurosurgery/Biopsy: Dr. Louis will perform this technique, which uses a needle guided to the tumor or it can be done during surgery when the surgeon can look at the tumor directly. This process is crucial as it will dictate the best course of treatment and will also give important information about prognosis.

Each treatment of an astrocytoma tumor depends on the type, size and location of the tumor. Although there are different variations of astrocytomas, the best course of action with astrocytomas is for surgical removal. Dr. Louis will recommend the best option to continue.

Dr. Louis may recommend radiation after surgery in the case that of lingering tumor cells. Patients will be observed carefully after for signs of astrocytoma reoccurance.
