Leptomeningeal Metastasis

Leptomeningeal metastasis is a serious condition where cancer spreads to the leptomeninges, the protective membranes surrounding the brain and spinal cord. This can occur when cancer cells break away from a primary tumor in another part of the body, such as the lungs or breasts, and travel through the bloodstream or cerebrospinal fluid. Symptoms may include headaches, confusion, seizures, and difficulty with balance. It indicates advanced cancer and generally requires specialized treatment, as it can complicate the management of the primary cancer and affect neurological function.
