[Occipital dermal sinus associated to a cerebellar abscess. Case].
Congenital dermal sinuses are tubular tracts which communicate the skin with deeper structures. It is a manifestation of defective separation of the ectoderm and neuroderm. The incidence is 1/2500-3000 births alive. Almost 10 % of congenital dermal sinuses are localized in the occipitocervical region. They are usually asymptomatic, unless an infectious process is concurrent (meningitis, abscess). We are presenting the case of a 12 months girl with unnoticed cutaneous stigmata in the occipital region, who was admitted with a meningeal syndrome and secondary neurological impairment. She had a cerebellar abscess and was treated with decompression by puncture of the abscess and antibiotics. When infection was resolved, congenital dermal sinus was excised. Process solves without morbidity. We reviewed the clinical and therapeutic features in cases reported previously in the literature.
