Abstract

INTRODUCTION

Hepatic small vessel neoplasm (HSVN) is a recently described vascular neoplasm of the liver that can mimic hepatic angiosarcoma (AS) because of its infiltrative nature but is considered benign or, at most, low-grade. HSVN appears to demonstrate a benign clinical course with no reported recurrences or metastatic disease, although its long-term malignant potential is uncertain.

CASE PRESENTATION

We present a 57-year-old man with an incidentally growing segment VII lesion that displayed features concerning for a neoplasm. He underwent a posterior sectionectomy and final histopathology confirmed a 27 mm HSVN. As the long-term malignant potential of HSVN is uncertain, he will be followed up with serial MRI scans over the next 5 years.

DISCUSSION

HSVN is a recently described entity, it is uncertain what the long-term malignant potential of HSVN can be. Reported cases have not shown any evidence of disease progression.

CONCLUSION

There are no clear guidelines established on the duration of the follow-up of HSVN. More research needs to be done to determine further the natural history of these tumours and possible radiological criteria.

摘要

引言

肝小血管肿瘤(HSVN)是一种最近被描述的肝脏血管肿瘤,由于其浸润性,可模仿肝血管肉瘤(AS),但被认为是良性的,或至多为低级别。HSVN似乎表现出良性临床过程,虽未见复发或转移性疾病的报道,但其长期恶性潜能尚不确定。

病例报告

我们报告一名57岁男性,其肝段VII偶然出现一个不断增大的病变,表现出肿瘤相关特征。他接受了肝后段切除术,最终组织病理学确诊为27毫米的HSVN。由于HSVN的长期恶性潜能尚不确定,他将在未来5年接受系列磁共振成像扫描随访。

讨论

HSVN是一种最近被描述的实体,其长期恶性潜能尚不确定。已报告的病例未显示任何疾病进展的证据。

结论

目前尚无关于HSVN随访时长的确切指南。需要开展更多研究以进一步确定这些肿瘤的自然病程及可能的影像学标准。
