Lobulated margination of liver hemangiomas: Is this a definitive feature?

초록

Purpose: To evaluate the occurrence rate of lobulated margination of hepatic hemangiomas. Methods: The study population included 585 hemangiomas in 261 patients (161 females; mean age: 51.9 years). Two readers independently reviewed all cases. Results: Hemangiomas with lobulated margins accounted for 74.7% of all lesions. The incidence of lobulated margins was significantly higher (P<.001) in medium- and large-sized hemangiomas (77.6% and 99.5%, respectively). The majority of hemangiomas with type-3 enhancement showed lobulated margins (83.5%) (P<.001). Conclusion: Virtually, all hemangiomas>18 mm show lobulated margins. The majority of hemangiomas with type-3 enhancement show lobulated margins. Lack of lobulated margins in larger lesions lowers the likelihood ratio for being hemangiomas. (C)2016 Elsevier Inc.
