Answer

The main cause of acalculous cholecystitis is gallbladder stasis with resulting stagnant bile. This is observed most commonly in patients with sepsis, patients in intensive care units, patients on long-term total parenteral nutrition (TPN), those with cardiovascular disease, [2] patients with diabetes (occasionally), or other patients with gallbladder dysmotility. The condition has been reported during pregnancy, as a complication of hepatitis A. [5] It has been rarely reported in children, also as a complication of hepatitis A, [6] with a favorable course with conservative treatment. This disease has also been reported as associated with aortic dissection. [7]
