Meningioma

A meningioma is a tumor arising from the membranes that cover the brain and spinal cord. Many are noncancerous, but their location and size can cause serious symptoms or require treatment. Risk factors and causes vary. In pharmaceutical or product litigation involving meningioma, a diagnosis alone does not establish causation. The analysis may include pathology, imaging, drug exposure history, dose, duration, scientific studies, biological evidence, and alternative risk factors.
