Robert Louis, MD, Fellowship-Trained Brain Surgeon
Specializes in Brain Tumor Surgery in Orange County, California

Robert Louis, MD, Brain Tumor SurgeonRobert Louis, MD specializes in minimally invasive of Brain Tumor Surgery in Orange County, California. Dr. Louis, a fellowship-trained Orange County Neurosurgeon, is the Director of the Skull Base and Pituitary Tumor Program at Hoag Memorial Hospital in Orange County, California. He has particular expertise in endoscopic and minimally invasive treatment of benign and malignant brain tumors, sellar and parasellar tumors and skull base tumors. Through the use of cutting-edge neuroimaging and neuro-navigational equipment, Dr. Louis utilizes the concept of keyhole neurosurgery, which minimizes the damage to vascular and soft tissues surrounding the brain.

Dr. Louis believes that most brain and skull base tumors can be resected through small openings or by utilizing naturally occurring orifices using . This approach has been demonstrated to decrease lowers the post-operative risks and pain, minimize neurologic complications and shorten length of hospitalization, resulting in better outcomes for his patients. Minimally invasive Brain Tumor Surgeries is performed using computer-assisted tools for more accuracy in removing tumors.

Types of Brain Tumors

Benign brain tumors consist of cells that grow slowly and do not spread to other areas of the brain or body like normal cells do. They have distinct boundaries and their appearance is different from cancerous cells. With the availability of advanced diagnostic technology in Orange County such as CT or Computer Tomography and MRI or magnetic resonance imaging, the brain can be scanned with higher resolution to help detect and confirm diagnosis of brain tumors.

Characteristics of Benign Tumor

  • Cells multiply slowly or grows slowly
  • Smooth and round with a surrounding fibrous lining
  • Tumor is mobile and does not attach to surrounding tissues
  • Does not metastasize or spread to other organs
  • Easier to remove and rarely recurs after excision
Malignant brain tumors are fast growing cancerous cells that metastasizes to different parts of the brain if not treated, removed or destroyed. When malignant or cancerous tumors spread, it will destroy surrounding tissues and organ. It is fatal when organs are affected by cancer or if a vital organ, like brain, lungs or liver are extensively damaged. Most cancerous or malignant brain tumors are secondary cancers, resulting from mestastasis. Tumors that start in the brain are called primary brain tumors and are named after the type of cell they developed from.

Characteristics of Malignant Tumor

  • Ulcerating or fixed mass
  • Irregular shape with no surrounding lining
  • Cells multiply rapidly
  • Tumor grows, destroys and invades surrounding tissues
  • Fixed mass, attached to surrounding tissues
  • Spreads to other organs or metastasizes
  • More difficult to remove and high chances of recurrence after excision or removal
