Abnormal cerebrospinal fluid morphology

What it means

An abnormality of the cerebrospinal fluid (CSF).

The cerebrospinal fluid (CSF) is secreted by the choroid plexus, and flows uninterrupted throughout the central nervous system (the central cerebrospinal canal of the spinal cord and through the four interconnected cerebral ventricles in the brain).

Rare diseases that can present with this13

The range is how often this sign appears among people diagnosed with each disease — it is not a probability of having any of them. Many of these signs also occur in common, non-rare conditions, and Orphanet separately records 9 diseases where this sign is specifically absent. A sign on this page is a conversation to have with a clinician, not a conclusion.
