Acute torsion of the gallbladder in a 100-year-old female patient.

Torsion of the gallbladder is rare. However, the surgeon should be aware of it and that unusual presentations in the elderly make early diagnosis very difficult. A 100-year-old white female presented with right-sided abdominal pain and was found to have acute torsion of the gallbladder. The clinical picture, diagnostic tests, and operative findings are outlined. Serial evaluations of the patient's condition and a high index of suspicion are essential elements for prompt recognition and early surgical management.
