The authors report a case of partial Currarino syndrome in a three and a half year old child with a left hemisacrum agenesis and a presacral mature teratoma. The special aspect of the observation was the apparition of repetitive polymicrobial purulent meningitis (Escherichia coli, Streptococcus B, Haemophilus influenzae) treated several times with non-specific antibiotics without normalization of CSF, particularly the CSF glucose, which remained low, justifying the use of an antimycobacterial treatment, especially since there was no local or general cause explaining the relapse. During a relapse of meningitis after ten months of antituberculosis treatment, the teratoma was discovered by a spine MRI done to detect any cerebrospinal defect. The authors insist on the fact that the Currarino syndrome must be investigated in case of repetitive purulent meningitis after ruling out the usual causes of meningitis.
