Gallbladder Volvulus Presenting as Acute Appendicitis.

Gallbladder volvulus is a rarely reported and diagnosed condition. We present a case of an elderly female with right lower quadrant pain mimicking acute appendicitis without conclusive imaging; however, due to worsening serological laboratory findings and sepsis picture, an exploratory laparotomy was performed. A necrotic gallbladder was removed, diagnosing gallbladder volvulus. A systemic literature review showed the difficulty in making a diagnosis and the uniqueness of our patient presentation. A high level of clinical suspicion for gallbladder volvulus must be maintained and should be included in the differential diagnosis in elderly women with an acute abdomen, as complications can be severe.
