Abstract
BACKGROUND

Hepatic hemangioma represents the most common benign primary hepatic neoplasm. Although most such tumors are small and asymptomatic, giant cavernous hemangioma (GCH) is frequently symptomatic, and needs intervention. Moreover, diffuse hepatic hemangiomatosis (DHH) is not rare in the liver parenchyma adjacent to a GCH. The management strategy for hepatic hemangiomas can differ depending on the presence of associated hemangiomatosis and the amount and distribution of the residual hepatic parenchyma.

CASE SUMMARY

Herein, we report two patients with GCH coexistent with DHH successfully treated by laparoscopic microwave ablation. The two GCHs were ablated completely and the ablated zone atrophied obviously in imaging follow-ups after ablation. Surprisingly, there was a trend toward gradual reduction and diminishment of DHH.

CONCLUSION

Thermal ablation treatment might be an effective and less invasive treatment for GCH coexistent with DHH around the hemangioma.

Core Tip: Hepatic hemangiomas are the most common benign liver tumors, with giant cavernous hemangioma (GCH) often requiring intervention. This report discusses two patients with GCH coexistent with diffuse hepatic hemangiomatosis (DHH), treated successfully with laparoscopic microwave ablation. Both GCHs were completely ablated, showing significant atrophy on follow-up imaging. Notably, there was also a gradual reduction in DHH. These findings suggest that thermal ablation may be an effective and minimally invasive option for managing GCH coexistent with DHH.
