[Meningitis associated with congenital dermal sinus]

Three cases of congenital dermal sinus associated with recurrent meningitis are presented. Severe neurological sequelae were seen in the three patients because diagnosis was done too late. Authors emphasize the necessity of doing in these patients a meticulous visual exploration of the middle line on the skin from occipital to coccyx zones searching some defect in order to perform myelography and to make an early extirpation of the intraspinal tumor and to close congenital dermal defect.
