Case description

A 47-year-old man with a history of traumatic brain injury (TBI) presented to the hospital with altered mental status. His initial brain injury occurred 3 years before when he was found at the bottom of a staircase and admitted to the hospital with Glasgow Coma Scale score of 6. He was found to have extensive bifrontal brain contusions overlying the anterior cranial fossa. Due to elevated intracranial pressure, he underwent urgent bicoronal craniectomy in addition to tracheostomy and gastrostomy placement. He subsequently developed chronic, refractory hyponatremia requiring daily sodium chloride tablets and new-onset orthostatic hypotension which improved with fludrocortisone. He had no history of documented hypercalcemia, abnormal thyroid function tests, elevated glucose, or hemoglobin A1C levels. Non-contrast head CT was performed to assess confusion and somnolence. Axial CT images revealed bilateral auricular cartilage calcification which had not been recognized on...
