WebHydrocephalus Overview Hydrocephalus is a condition characterized by an abnormal accumulation of cerebrospinal fluid (CSF) within the ventricles of the brain. CSF surrounds the brain and spinal cord. WebMRI also gives detailed images of soft tissue structures and is often particularly useful to help identify the specific cause of hydrocephalus. Lumbar puncture – a small needle is inserted into the lower part of the spine (lumbar spine) under local anaesthetic to obtain a small sample of cerebrospinal fluid (CSF) and to measure CSF pressure.
