A 35-year-old woman underwent percutaneous cholecystostomy tube placement for acute cholecystitis due to multiple comorbidities preventing cholecystectomy. Following cholecystostomy tube placement, the patient became mildly tachycardic and complained of severe abdominal pain without a significant change in blood pressure. Axial noncontrast CT image of the abdomen reveals a hyperdense fluid collection within the gallbladder (arrow) after cholecystostomy tube placement, representing acute hemorrhage/hematoma.
