Pneumocephalus in the absence of trauma, tumour, or surgery is a rare entity. We report a case of a 73-year-old lady who presented with sepsis leading to confusion and unresponsiveness. A CT of brain revealed mastoiditis, sinusitis, and associated pneumocephalus. Further investigations led to an eventual diagnosis of pneumococcal meningitis. The combination of pneumocephalus and meningitis as complications of mastoiditis is rare with very few cases published in the literature. We describe one such case.
