Intradiploic meningoencephalocele

We report on a 36-year-old patient who presented with coordinative problems in his right leg. The MRI study of his brain showed the extremely rare intradiploic meningoencephalocele which explained his symptoms. Most cephaloceles are inborn developmental disturbances and present with symptoms of different severity depending on the degree of associated malformations in early childhood. They usually demand immediate treatment. In the patient presented here the cephalocele belongs to the rare type of intradiploic meningoencephalocele. This is a variant of the intradiploic cerebrospinal fluid cyst and of traumatic instead of developmental origin.
