Mirizzi syndrome is an unusual complication due to gallstones. Preoperative diagnosis is very important because there is a risk of injury to the inflamed gallbladder and gallbladder duct during surgical treatment of a patient with Mirizzi syndrome. However, preoperative diagnosis is difficult despite modern imaging techniques, since it does not have a pathognomonic image. For this reason, Mirizzi syndrome can often be diagnosed intraoperatively. The treatment is surgery. In this case report, an 85-year-old male patient who was admitted to the hospital due to fever rising with chills is presented. The patient was hospitalized for recurrent episodes of fever. As a result of the development of fever during antibiotic use, magnetic resonance imaging with intravenous contrast was obtained and the patient was diagnosed with Mirizzi syndrome and treated thereafter.
