Minimally invasive treatment of hepatic hemangioma by transcatheter arterial embolization combined with microwave ablation: A case report

Figure 1 Computed tomography suggested a right hepatic hemangioma. A: Plain; B: Arterial phase; C: Venous phase.

Figure 2 Ultrasound angiography showed that the right posterior hepatic lobe displayed a strong echogenic area with a size of 95 mm × 97 mm × 117 mm. A: Ultrasound indicated a liver hemangioma; B: In contrast mode, after injection of sulfur hexafluoride microbubbles; C: In contrast mode, the contrast agent filled slowly.

Figure 3 Right liver. A and B: Large abnormal staining area in the right liver; C: Abnormal staining area disappeared.

Figure 4 Partial images of radiofrequency ablation guided by ultrasound. A: Right posterior hepatic lobe lesion in the posterior segment, energy: 55 W × 600 s; B: Right posterior lobe lesion in the middle of the posterior region, energy: 55 W × 600 s; C: The dynamic observation of the mass area was covered by a strong echo.

Figure 5 Results of ultrasound and computed tomography reexaminations after treatment. A: After transcatheter arterial embolization; B: 2 mo after discharge; C: 1 year after discharge.
