Primary Occipital Encephalocele in an Elderly Patient.

The encephalocele is a condition characterized by the protrusion of the intracranial contents through a bone defect of the skull. The authors report a clinical case of an 80-year-old woman with primary occipital encephalocele on the right side and that was affected by trauma and presented liquor fistula and infection. Tomographic sections were obtained by injection intravenous of contrast. The images showed bone thickness thinning on the right occipital region and solution of continuity (encephalocele) with regular contours, reduction in brain volume, and hypodensity of the periventricular white substance were observed. The patient was successfully operated.
