Research on size abnormalities in the brains of people with OCD has led to many contradictory findings. Based on the current evidence, the only reliable conclusion that can be made is that OCD is a heterogeneous disorder. While some studies suggest dysfunction in the caudate nucleus, others do not. I think that it's safe to say that in some people with OCD, regions such as the caudate nucleus are dynfunctional (perhaps due to excessive glutamate activity); however, note that the finding probably doesn't apply to everyone with this disorder. There are several other regions that have been studied as well; the caudate nucleus is probably one of the most examined, however.
See http://www.neurotransmitter.net/ocdimaging.html for several abstracts on OCD neuroimaging studies.
