Summary
I have dedicated my life’s work to the surgical treatment of children with brain and spinal disorders. I am internationally recognized for my deep experience in challenging surgeries. These include removing tumors near the spine and in the ventricles of the brain (called intraventricular brain tumors); managing tumors in the pineal gland, also in the brain; treating congenital cysts, which are present in the body at birth; and correcting Chiari malformation, a condition in which tissue from the brain extends into the spinal canal. I perform about 300 surgeries each year; many of them are minimally invasive.
Featured Review
Dr. Souweidane removed a large (17 mm) colloid cyst from my ventricle on 4/22/2025. He was excellent and I have the utmost confidence in him. He’s confident that he got the whole thing, so I think I can be assured that it will likely be gone for good! I sure do hope that this is something I can put behind me for good and get rid of the cognitive issues I’ve been experiencing, though he’s unsure that they’re a result of the cyst. I hope they are and that now is the time to start healing. Time will tell the tale.
