Background: To describe cerebellar abnormalities in a family composed by a father and two affected sibs with Adams Oliver syndrome (AOS) (OMIM 100300).
Material/methods: Brain MRI and MR angiography were performed at 1.5T.
Results: The siblings presented cerebellar cortex dysplasia characterized by the presence of cysts.
Conclusions: Abnormalities of CNS are an unusual manifestation of AOS. To our knowledge, this is the first report of cerebellar cortical dysplasia in a family with AOS.
Keywords: Adams Oliver syndrome; MRI; cerebellar cortical dysplasia; cerebellar cysts.
