Cardiopulmonary resuscitation (CPR) is an important life-saving procedure in emergency care. However, CPR is associated with various complications. A 41-year-old man was admitted to the intensive care unit after CPR. A sudden decrease in the blood pressure and hematocrit level was recorded. An abdominal computed tomography (CT) showed a large subcapsular hematoma in the left lobe of the liver. With conservative treatment, the hematoma reduced in size, but it was later managed with percutaneous drainage. The patient recovered and was discharged. We obtained a favorable outcome with conservative, nonsurgical treatment. Subcapsular hepatic hematoma is a potential life-threatening complication that should be considered in CPR survivors.
