A 56-year-old man with a subcapsular hepatic hematoma diagnosed by abdominal computed tomography (CT). a Contrast-enhanced abdominal CT at the time of diagnosis. The hematoma is visible beneath the capsule of the right hepatic lobe (black arrows). b–d Percutaneous CT-guided drainage and transarterial embolization (TAE) are performed on Day 34 after the initial examination. b Digital subtraction angiography of the right hepatic artery. This artery is deviated, and the hepatic parenchyma is displaced by the hematoma (black arrowheads). The white arrow indicates the drainage catheter. There is no sign of contrast medium extravasation or an isolated artery. c Digital subtraction angiography of the right inferior phrenic artery. There is no sign of contrast medium extravasation or an isolated artery. d Digital subtraction angiography of the right hepatic artery after embolization. Blood flow is stopped in the periphery of the right hepatic artery. e Contrast-enhanced abdominal CT after percutaneous CT-guided drainage and TAE. The hematoma (black arrows) can be seen to have decreased in size. f Contrast-enhanced abdominal CT 1 month after TAE. The hematoma (black arrows) has not been resorbed, but it has started to regrow
