Abstract

Objective: To evaluate the contrast enhanced ultrasound (CEUS) and contrast enhanced magnetic resonance imaging (CEMRI) features of intrahepatic splenosis (IHS).

Methods & materials: Five patients (three males and two females, median age, 44 years; range,32-73 years) with seven IHSs were retrieved from the database of our hospital from March 2012 to October 2021. All IHSs were confirmed histologically by surgery. The CEUS and CEMRI characteristics of individual lesion were fully analyzed.

Results: All IHS patients were asymptomatic and four out of five patients had history of splenectomy. On CEUS, all IHSs were hyperenhancement in arterial phase. 71.4% (5/7) of IHSs manifested overall filling within few seconds, the other two lesions showed centripetal filling. Subcapsular vascular hyperenhancement and feeding artery was seen in 28.6% (2/7) and 42.9% (3/7) of IHSs, respectively. During portal venous phase, IHSs presented hyperenhancement (2/7) or isoenhancement (5/7). Moreover, rim-like hypoenhanced area was uniquely observed surrounding 85.7% (6/7) of IHSs. In late phase, seven IHSs remained continuous hyper- or isoenhancement. On CEMRI, five IHSs showed mosaic hyperintense in early arterial phase, the other two lesions showed homogeneous hyperintense. In portal venous phase, all IHSs revealed continuous hyper- (71.4%, 5/7) or iso-intense (28.6%, 2/7). During late phase, one IHS (14.3%, 1/7) became hypointense, the other lesions remained hyper- or isointense.

Conclusion: Diagnosis of IHS can be based on typical CEUS and CEMRI features in patients with history of splenectomy.

肝内脾肿大：对比增强超声波和磁共振成像结果。

目的评估对比增强超声（CEUS）和对比增强磁共振成像（CEMRI）的肝内脾肿大（IHS）特征：2012年3月至2021年10月期间，从我院数据库中检索到5名患者（3男2女，中位年龄44岁；年龄范围32-73岁）共7例IHS。所有 IHS 均经手术组织学证实。对每个病灶的CEUS和CEMRI特征进行了全面分析：所有IHS患者均无症状，其中五分之四的患者有脾切除史。在 CEUS 上，所有 IHS 在动脉期均呈高强化。71.4%（5/7）的 IHS 在数秒内表现为整体充盈，另外两个病灶表现为向心性充盈。分别有28.6%（2/7）和42.9%（3/7）的IHS可见囊下血管增生和供血动脉。在门静脉期，IHS呈高增强（2/7）或等增强（5/7）。此外，在 85.7%（6/7）的 IHS 周围可观察到边缘样低增强区。在晚期，7 个 IHS 仍持续高或等强化。在 CEMRI 上，5 个 IHS 在动脉早期呈镶嵌高密度，另外两个病灶呈均匀高密度。在门静脉期，所有 IHS 均显示为连续性高强化（71.4%，5/7）或等强化（28.6%，2/7）。在晚期，一个IHS（14.3%，1/7）变得低密度，其他病变仍保持高密度或等密度：结论：对于有脾切除史的患者，可根据典型的 CEUS 和 CEMRI 特征诊断 IHS。

期刊介绍： Clinical Hemorheology and Microcirculation, a peer-reviewed international scientific journal, serves as an aid to understanding the flow properties of blood and the relationship to normal and abnormal physiology. The rapidly expanding science of hemorheology concerns blood, its components and the blood vessels with which blood interacts. It includes perihemorheology, i.e., the rheology of fluid and structures in the perivascular and interstitial spaces as well as the lymphatic system. The clinical aspects include pathogenesis, symptomatology and diagnostic methods, and the fields of prophylaxis and therapy in all branches of medicine and surgery, pharmacology and drug research. The endeavour of the Editors-in-Chief and publishers of Clinical Hemorheology and Microcirculation is to bring together contributions from those working in various fields related to blood flow all over the world. The editors of Clinical Hemorheology and Microcirculation are from those countries in Europe, Asia, Australia and America where appreciable work in clinical hemorheology and microcirculation is being carried out. Each editor takes responsibility to decide on the acceptance of a manuscript. He is required to have the manuscript appraised by two referees and may be one of them himself. The executive editorial office, to which the manuscripts have been submitted, is responsible for rapid handling of the reviewing process. Clinical Hemorheology and Microcirculation accepts original papers, brief communications, mini-reports and letters to the Editors-in-Chief. Review articles, providing general views and new insights into related subjects, are regularly invited by the Editors-in-Chief. Proceedings of international and national conferences on clinical hemorheology (in original form or as abstracts) complete the range of editorial features.
