The Dermal Sinus: About 29 Cases and Review of the Literature

The term spina includes several types of congenital malformations including closed spinal dysraphisms, among these 10% are dermal sinuses.Our series includes 29 patients, the majority of which were asymptomatic, but these can present with different clinical pictures including neurological and / or infectious signs indicating a neglected dermal sinus and which therefore requires urgent treatment in the environment. Neurosurgical.MRI confirmed the diagnosis showing the dermal sinus tract communicating from the surface of the skin to the intra-dural space.Once the diagnosis has been made, surgical treatment becomes imperative and urgent because, despite the benignity of the lesion, the majority of which are located in the lumbar region, can lead to formidable neurological sequelae compromising the functional prognosis or even the vital prognosis in some cases.All of our patients were operated on and we obtained 90% good results, however we deplore one case of aggravation and one death.
