Summary table of Hemorrhagic Cholecystitis.

Etiology	Hemorrhagic cholecystitis is most often related to gallstone impaction in the gallbladder neck with erosion of the adjacent cystic artery leading to the formation of a pseudoaneurysm.
Incidence	Exact incidence is unknown as it is believed to sometimes be unrecognized and misdiagnosed.
Gender Ratio	No
Age Predilection	No
Risk Factors	Patients with gallstones, hypercoagulable state/platelet dysfunction, anticoagulation therapy, atherosclerosis, and/or trauma.
Treatment	A two-step therapeutic approach should first include embolization of the culprit vessel, followed by definitive cholecystectomy.
Prognosis	Variable prognosis depending on clinical presentation and potentially fatal if not detected. Early diagnosis is essential to facilitate urgent intervention and surgical treatment.
Findings on Imaging	Distended gallbladder containing blood products. The most specific imaging finding is the identification of a cystic artery pseudoaneurysm.
