Recurrent meningitis associated with complete Currarino triad in an adult--case report

A 58-year-old woman presented with Currarino triad manifesting as recurrent meningitis. Currarino triad is a combination of a presacral mass, a congenital sacral bony abnormality, and an anorectal malformation, which is caused by dorsal-ventral patterning defects during embryonic development. She had a history of treatment for anal stenosis in her childhood. Radiographic examinations demonstrated the characteristic findings of Currarino triad and a complicated mass lesion. The diagnosis was recurrent meningitis related to the anterior sacral meningocele. Neck ligation of the meningocele was performed via a posterior transsacral approach after treatment with antibiotics. At surgery, an epidermoid cyst was observed inside the meningocele. The cyst content was aspirated. She suffered no further episodes of meningitis. The meningitis was probably part of the clinical course of Currarino triad. Radiography of the sacrum and magnetic resonance imaging are recommended for patients with meningitis of unknown origin. The early diagnosis and treatment of this condition are important.
