Temporal Arteritis Presenting with Gastrointestinal Symptoms in a Middle Aged Man

Giant cell arteritis, also known as temporal arteritis, is a vasculitis of unknown etiology that classically involves the wall of the large to medium size. We are reporting a case of a young onset temporal arteritis presenting with gastrointestinal symptoms. The patient was a 48-year-old male who presented with a 2-week history of fever, diffuse abdominal pain, and malaise. He underwent a laparoscopic cholecystectomy after findings of elevated bilirubin and alkaline phosphatase as well as suspicion of porcelain gallbladder on ultrasound (or computed tomography scan). The patient subsequently developed painless, intermittent vision loss and unilateral headaches. A work-up included temporal artery biopsy, which showed marked lymphocytic infiltrate in the arterial wall consistent with temporal arteritis. The presentation of temporal arteritis may be atypical.
