Alagille syndrome: case report with bilateral radio-ulnar synostosis and a literature review.

We report a case of Alagille syndrome (arteriohepatic dysplasia) with the unusual radiological abnormality of synostosis of the proximal portions of the radius and ulna bilaterally, a manifestation which, to our knowledge, has not previously been described in a specific patient in the English language literature. We also describe additional features of the syndrome in the same patient and review the published literature on radiological manifestations of this condition.
