Familial malrotation: report of three affected siblings.

We herein report the case of three siblings presenting with intestinal malrotation. Their medical history and circumstances of diagnosis are described. Barium meal demonstrated a minor duodenal anomaly in the mother. As far as we can ascertain, this is the third report of isolated familial malrotation in more than one generation, raising questions about its developmental mechanism. We thus highlight in what circumstances familial investigations should be undertaken in case of malrotation.
