AB  - Summary: A 70-year old man with a 15-year-history of chronic daily Valsalva maneuvers for left ear congestion presented with worsening vertigo and calvarial (occipitoparietal) and upper cervical hyperpneumatization. With continued frequent Valsalva maneuvers, subsequent studies demonstrated increased pneumatization with extension of air into the epidural space, causing mass effect on the left parietal lobe. Four months after discontinuing the habitual Valsalva maneuvers, CT demonstrated resorption of the epidural air and partial regression of the calvarial pneumatization.
