BACKGROUND Intracranial pneumocephalus, the accumulation of air, occurs most frequently from trauma, tumor, cranial surgeries, or infection. Intraparenchymal otogenic pneumocephalus is a rare but well-documented development. We describe a patient who developed pneumocephalus in the context of eardrum perforation secondary to toothpick use for ear wax. CASE DESCRIPTION An 86-year-old female presented to the emergency room with one day history of dysarthria and a few days of cough and sneezing. History revealed she had recently been advised to avoid q-tips to clean her ears and instead was using toothpicks. She denied otalgia or otorrhea and had no signs of infection near the ear. On otoscopic exam the right tympanic membrane was perforated. On head CT she was found to have a large right temporal pneumocephalus extending from the petrous bone. Magnetic resonance imaging of the brain revealed a defect in the right tegmen. She was started on empiric antibiotics and subsequently taken to the operating room for craniotomy and repair of bony and dural defects. CONCLUSIONS Otogenic pneumocephalus is a rare occurrence. This is the first reported case of pneumocephalus related to self-induced middle ear trauma with a toothpick that ultimately required craniotomy for repair.
