Spontaneous Pneumoventricle Following Bariatric Surgery

Pneumoventricle is a common postoperative event following posterior fossa approach, or any transventricular approach, with a benign evolution, rarely life-threatening. However, spontaneous pneumoventricle is a rare condition, almostalways secondary to cerebrospinal fluid (CSF) leakage, with possible worse evolution. We report a 57 years-old woman, previously healthy, submitted 7 months previously to a bariatric surgery, with 110 pounds (50 Kg) weight loss since that, who developed 1 month later headache, hemiparesis and urinary incontinence, secondary to a spontaneous pneumoventricle.
