This study aims to investigate the ultrasonographic characteristics of early hepatic alveolar echinococcosis (HAE) and improve the qualitative diagnostic ability of sonographers.
The data of 80 positive cases of HAE screened and diagnosed by ultrasonography and serum immunology (33 males and 44 females with a mean age of 44.12 ± 14.31 y) were used in the study. The imaging characteristics of the lesions (i.e., intrahepatic distribution, shape, size, echo, blood flow, and growth characteristics) were analyzed retrospectively, and the ultrasonographic characteristics of early lesions were discussed in combination with their basic pathological changes.
Patients with lesions of the proliferative infiltration type accounted for 57.5% (46/80), the fibrous calcification type accounted for 26.25% (21/80), the necrotic liquefaction type accounted for 6.25% (5/80), and the mixed type accounted for 10% (8/80). Patients with lesions involving the right lobe and the left lobe accounted for 76.25% (61/80) and 11.25% (9/80), respectively, and with lesions involving both the left and right lobes accounted for 12.5% (10/80). There were statistically significant differences in diameter between all types of lesions ( = 88; F = 5.926 and = 0.004). Focal hyperechoic and diffuse heterogenous nodular changes were the main manifestations of early proliferative infiltration lesions.
Ultrasonography is extremely valuable in the diagnosis of early HAE. Capillary hemangioma-like changes and hailstorm sign are the main characteristics of early lesions of HAE, and calcification is a common concomitant sign.
本研究旨在探讨早期肝泡型包虫病（HAE）的超声特征，提高超声诊断医师的定性诊断能力。
本研究采用经超声检查及血清免疫学筛查诊断的80例HAE阳性病例资料（男33例，女44例，平均年龄44.12±14.31岁）。回顾性分析病灶的影像学特征（即肝内分布、形态、大小、回声、血流及生长特征），并结合其基本病理变化探讨早期病灶的超声特征。
增殖浸润型病灶患者占57.5%（46/80），纤维钙化型占26.25%（21/80），坏死液化型占6.25%（5/80），混合型占10%（8/80）。病灶累及右叶和左叶的患者分别占76.25%（61/80）和11.25%（9/80），累及左右两叶的病灶占12.5%（10/80）。各类型病灶直径差异有统计学意义（=88；F=5.926，=0.004）。局灶性高回声及弥漫性不均匀结节状改变是早期增殖浸润性病灶的主要表现。
超声检查对早期HAE的诊断具有极高价值。毛细血管瘤样改变及暴风雪征是HAE早期病灶的主要特征，钙化是常见的伴随征象。
