Parasagittal Meningiomas Symptoms

By Rae Uddin ; Updated August 14, 2017

A meningioma is a type of tumor that develops within the membranes that cover the brain and spinal cord, which are called the meninges. Parasagittal meningiomas form near the falx, a groove that runs along the brain from front to back, according to medical experts at the Brigham and Women's Hospital. People who develop parasagittal meningioma symptoms should consult a physician for further evaluation and care.

Headache

A parasagittal meningioma can increase the normal pressure levels within the brain. This pressure elevation can cause headache symptoms in people with this condition, explain health professionals with the Mayfield Clinic. The severity of headache pain can range from mild to severe and can localize within any region of the head. Sudden, severe headaches can also be a sign of a stroke, and affected people should seek prompt medical care to ensure receipt of appropriate care.

Leg Weakness

Leg weakness can occur as a symptom of a parasagittal meningioma in affected patients. Typically, a meningioma that forms on the left side of the falx causes right leg weakness, while a meningioma that forms on the right side of the falx causes left leg weakness, explain medical experts with the Merck Manual. In certain cases, sensations of weakness can affect both legs. People who develop unusual sensations of leg weakness due to a parasagittal meningioma can experience difficulty standing or walking normally.

Vision Problems

Increased pressure within the brain caused by a parasagittal meningioma can affect the optic or eye nerve. If the optic nerve is damaged or pinched, people with a parasagittal meningioma can develop vision problems as a symptom of this condition, report health experts with the Mayfield Clinic. Affected people can experience blurred or cloudy vision, which may contribute to headache symptoms or sensations of dizziness.

Congitive Dysfunction or Personality Changes

Parasagittal meningiomas that develop near the front portion of the falx can lead to significant brain dysfunction in affected people, warn medical professionals with the Brain Science Foundation. People with this condition can experience unusual memory loss or can have difficulty with logical decision-making. Certain people with parasagittal meningiomas can also experience abnormal personality changes, which may be most apparent to close friends or family members. A person who is normally quiet or reserved can suddenly become talkative and outgoing. Alternatively, social people may appear abruptly withdrawn or depressed. These unusual changes in cognition and personality associated with a parasagittal meningioma should be discussed with a medical professional as soon as possible.
