Rock star Sheryl Crow recently revealed she was diagnosed with a meningioma, a type of brain tumor that grows in the meninges, the layers of tissue covering the brain and the spinal cord. According the National Brain Tumor Society, as the tumor grows, it compresses brain tissue, causing a variety of symptoms including seizures, headaches, nausea and vision changes. Crow, 50, said she sought help after having trouble remembering the words of her songs. Memory loss is also a common symptom. The tumors are usually nonmalignant and grow slowly. Many individuals with meningiomas don't ever know they have the tumors unless they get their brains scanned for other reasons. They occur most often in a person's 40s and 50s, and are twice as common in women as in men.
The only treatment for the tumor is surgery, but many patients can live a full life with untreated tumors. Crow will reportedly monitor the growth of the tumor with regular MRIs, but does not have immediate plans for surgery.
