What does "No CSF leak" mean in a report or doctor's letter? In our medical dictionary, you will find a patient-friendly explanation of the meaning of this medical term.
"No CSF leak" refers to the absence of a medical condition where the fluid that surrounds the brain and spinal cord, known as cerebrospinal fluid (CSF), is not leaking out. This fluid is important because it acts as a cushion for the brain, protecting it from injury. A leak can occur due to injury, surgery, or spontaneously, and can lead to headaches and other symptoms. Therefore, "No CSF leak" means that this protective fluid is contained as it should be, indicating no such problem.
