Abnormal corpus striatum morphology

What it means

Abnormality of the striatum, which is the largest nucleus of the basal ganglia, comprising the caudate, putamen and ventral striatum, including the nucleus accumbens.

The striatum (also known as the neostriatum or striate nucleus) contains the caudate nucleus and putamen, which are separated from one another by a white matter tract called the internal capsule. The striatum is part of the basal ganglia and receives input from the cerebral cortex. Essentially all cortical areas (sensory, motor and associational) project to the striatum. The other major input to the striatum comes from the thalamus, particularly the intralaminar thalamic nuclei.

Rare diseases that can present with this8

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. A sign on this page is a conversation to have with a clinician, not a conclusion.
