UK doctors find 9-cm-wide air pocket in man's brain

UK-based doctors have reported the discovery of a 9-cm-long air-filled cavity in the right lobe of a man's brain. The 84-year-old was presented to the emergency department following recurrent falls over several weeks and onset of new left-sided weakness. He was a non-smoker and drank rarely, doctors noted in their paper titled 'The man that lost (part of) his mind'.
