Physical examination revealed a thin elderly man with the following vital signs: temperature, 33.8°C; pulse, 55 beats/min; respirations, 20 breaths/min; and blood pressure, 118/80 mm Hg. Cardiovascular examination was significant for bradycardia. Lung examination revealed decreased bibasilar air movement without adventitious sounds. His abdomen was scaphoid and not tender. Extremities showed bilateral 3+ edema to the level of the knees. Laboratory data showed a WBC count of 4.0 × 103/mm3 (previously 7.1), potassium of 2.9 mEq/L, and BUN/creatinine of 82/3.65 mg/dL. Owing to the leukopenia, hypothermia, and change in mental status, a sepsis work-up was initiated. A prior chest radiograph (not shown) revealed pleural effusions (right greater than left), bilateral lower lobe infiltrates, and mild pulmonary edema. Bedside abdominal ultrasound (AUS) was performed. The following ultrasound (US) videos were taken with a high-frequency probe over the anterior surface of the liver with the patient at 20° upright (Videos 1, 2).
