Skull Base Defect Associated with Spontaneous Intraventricular Pneumocephalus in a Patient with Ventriculo-peritoneal Shunt

We report the case of an 81-year-old male patient who presented severe spontaneous intraventricular pneumocephalus after two months of ventriculoperitoneal shunt placement for adult chronic hydrocephalus associated with neurologic progressive deterioration and a recent history of hypoacousia. During the process of diagnosis, on simple and fine-cut Computerized Tomography a porencephalic cyst was discovered in association with an osteodural defect in the petrous bone. A surgical revision was scheduled and an approach to the tegmen tympani was performed, covering the defect with fasciomuscular flap and fibrin glue. There were no complications and a remarkable clinicoradiologic improvement was achieved.
