Abstract

Currarino's triad is a rare complex of a congenital sacral bony abnormality, anorectal malformation and a presacral mass. Intractable constipation since birth is the leading symptom of this triad, which follows an autosomal dominant mode of heredity. We report conventional radiographic and MR findings in one family consisting of a mother and her two daughters. In all three cases, radiography revealed an abnormality of the os sacrum, the so-called scimitar sacrum. MR examination, undertaken next in our institution, was applied with T1-, T2- and proton density weighted sequences in all three orientations before and after i. v. application of gadolinium diethylene-triamine-pentaacetic acid (Gd-DTPA). In two patients we were able to diagnose the complete form of the triad and in one patient an incomplete form. In any case of a radiographically diagnosed scimitar sacrum in combination with constipation, Currarino's triad should be considered. MRI, as the method of choice, should be the next step to detect a presacral mass and any anomalies of the spinal canal. The importance of early recognition lies in the high morbidity and mortality rates resulting from this disorder.
