====== Symptomatic pneumocephalus ======

Symptomatic [[pneumocephalus]] is an uncommon [[complication]] of [[neurosurgery]]. Reports of symptomatic pneumocephalus in [[deep brain stimulation]] (DBS) surgery are lacking, due to the rarity of this condition. 

Albano et al. described 2 patients who experienced clinically significant intraparenchymal pneumocephalus as a consequence of DBS surgery and report their clinical presentations, treatments, and outcomes.

The first patient was a 69-year-old woman with Parkinson disease and the second was a 73-year-old woman with medically refractory [[essential tremor]]. Both patients underwent [[DBS]] implantation and developed [[focal neurological deficit]]s in the days after surgery. In each case, immediate postoperative head [[computed tomography]] scans showed extra-axial[[ pneumocephalus]] which redistributed on subsequent imaging along the dorsal length of the lead. For each patient, a second surgery was carried out to evacuate the [[pneumocephalus]] without lead removal. Clinical symptoms and radiological signs of intracranial air were resolved on the last follow-up.

Symptomatic intraparenchymal pneumocephalus is a rare complication of [[DBS]] surgery which can be treated with surgical evacuation
