People with this condition in the brain may or may not experience symptoms. Some complications of the condition are life-threatening or cause major disruptions to normal functioning. Dangerous seizures due to compression of the brain, bleeding inside the brain tissue, vision problems, difficulty with speaking or using words, memory loss, ataxia, or hydrocephalus can occur. Less serious symptoms may include headaches and weakness or numbness in the arms or legs, though these symptoms alone do not indicate a person has the condition. In the eye, it may cause disruption or damage to the extraocular muscles and optic nerve which may manifest as double vision, progressive proptosis, decreased visual acuity, or other vision changes. It can lead to partial or complete blindness. When the condition occurs in the liver it usually does not cause symptoms, but some may experience pain in the upper right abdomen, a feeling of fullness after eating only a small amount of food, decreased appetite, nausea, or vomiting.
