Bacterial meningitis of an infant with Currarino triad.

Currarino triad is a rarely hereditary condition including: (1) an anorectal malformation, (2) an anterior sacral defect, and (3) a presacral mass. Autosomal dominant transmission is suggested. We reported one case of Currarino triad, who was a 3-month-old male with sacral dysgenesis, imperforated anus and enteric cyst. This case presented with acute lower limbs paralysis due to bacterial meningitis complicated with acute arachnoiditis. The diagnosis of this condition led to a work-up of his sibling, who was found to have an incomplete type. The purpose of this case is to emphasize that a high index of suspicion for timely diagnosis and treatment of Currarino triad could prevent devastating complications.
