A pineal tumor is a rare growth in or around the pineal gland, a small part of the brain that produces melatonin to regulate sleep. These tumors can block fluid flow in the brain, causing symptoms like headaches or vision problems. They can be slow- or fast-growing and are more common in children. The exact cause is unknown but may involve genetics or environmental factors.
Pineal tumors range from slow-growing pineocytomas (Grade I) to aggressive pineoblastomas (Grade IV), with intermediate types like PPTID and papillary tumors (Grade II/III). Mixed pineal tumors contain both slow- and fast-growing cells.
Pineal tumors can cause rapidly worsening symptoms like headaches, vision problems, nausea, balance issues, and memory trouble. In children, they may lead to growth or developmental delays.
At Southern California Brain & Spine Surgery, our team creates individualized treatment plans for pineal tumors, combining advanced technology with a strong focus on preserving your quality of life. Your treatment strategy is determined by the tumor’s size, type, location, and its effect on surrounding brain structures. Surgery is often the primary approach and may be followed by radiation therapy or chemotherapy when appropriate. In cases involving increased pressure from fluid buildup, a shunt may be placed to restore normal flow. For tumors that are difficult to access, we may recommend stereotactic radiosurgery, a non-invasive method that delivers highly targeted radiation with exceptional precision. Ongoing care includes regular MRI monitoring to detect any signs of recurrence, and patients can also consult with a second opinion neurosurgeon Los Angeles for additional guidance and clarity throughout the treatment process.
We begin with a thorough physical and neurological exam to assess reflexes, muscle strength, coordination, and eye and facial movements. If a pineal tumor is suspected, we use advanced diagnostic tools to pinpoint the cause with precision. Our state-of-the-art imaging technology helps us accurately diagnose and create the most effective treatment plan tailored to you. Technologies we use:

John Chavez2024-09-27Trustindex verifies that the original source of the review is Google. Moksha is caring, focused and a great surgeon. I interviewed another doctor before finding her and wasn’t at all impressed with him. Moksha on the other hand made me feel that I was important and that she would work on my problem, which she did and finally after about three years of pain and suffering I no longer have the pain that kept me housebound. I’m starting to feel better and I’ve even started walking around again. Soon I’ll be up to a mile each time I walk around and then two or three miles at a time. I am so happy that I “found” her to be my surgeon. If you have a chance ask for her help. You won’t be disappointed!

From the moment I met her, Dr. Ranasinghe put me right at ease. She's got such a warm, caring personality and you can just tell she really knows her stuff as a spine surgeon but spoke in very simple terms so I could understand. She was very thorough in explaining my MRI results and all the different surgery options and went over the pros and cons of everything, but never pressured me into a decision. In the end I opted for surgery a year later. Now, I'm almost pain-free for the first time in ages because of one amazing spine surgeon.

Pineal tumors often affect eye movement and pressure pathways. Patients may notice trouble looking upward, double vision, headaches, or nausea from blocked fluid flow. These patterns are distinctive for tumors in the pineal region.
Because of their location, pineal tumors can block normal cerebrospinal fluid circulation. This leads to hydrocephalus, increasing pressure in the brain and triggering headaches, nausea, and vomiting.
Yes, they can compress structures controlling eye coordination. Early treatment often improves visual symptoms, but prolonged pressure may cause lasting deficits. Prompt evaluation helps protect vision
Not all pineal tumors are malignant. Some are slow-growing and benign, while others are aggressive. Imaging and tissue diagnosis are essential to determine tumor type and guide treatment.
MRI is the primary tool to evaluate size, location, and fluid blockage. Additional tests may include blood markers or biopsy when safe. Careful planning is critical due to the tumor’s deep position.
Treatment may include surgery, radiation therapy, chemotherapy, or a combination. The approach depends on tumor type, size, and symptoms. Relieving fluid blockage is often the first priority.

At Southern California Brain & Spine Surgery, we develop personalized treatment plans for pineal tumors, using advanced technology to ensure the best possible outcomes while prioritizing your quality of life. Treatment depends on the tumor’s size, type, location, and impact on brain function. Surgery is often the primary approach, sometimes followed by radiation therapy or chemotherapy. In certain cases, a shunt may be placed to relieve pressure from fluid buildup. For hard-to-reach tumors, we may use stereotactic radiosurgery, a non-invasive technique that delivers precise, high-dose radiation. Ongoing follow-up with regular MRIs helps monitor for recurrence.
