为了使超声分类的不同阶段的化脓性肝脓肿，超声表现在86例患者的113化脓性肝脓肿进行了回顾性分析，并与建立病理形态学描述的疾病。超声造影的典型表现为动脉期亚段充血（93/113，82%）和坏死伴边缘充血（109/113，96%），晚期坏死周围肝组织被冲洗（101/113，89%）。化脓性肝脓疡的形态学分期可分为四个阶段。I期定义为无坏死的局灶性炎症（n = 2）; II期定义为出现合并的局灶性微囊簇（n = 41）; III期定义为有或无包膜的单个腔（n = 64）。IV期定义为肝脏各处散布许多小脓肿（n = 6）。结果表明，超声造影可用于化脓性肝脓肿的分期。对所描述的形态学模式的了解影响治疗决策，并有助于区分肝占位性病变和其他肝占位性病变。(C)2015年世界医学和生物学超声联合会。
To enable sonographic classification of different stages of pyogenic liver abscesses, sonographic findings in 86 patients with 113 pyogenic liver abscesses were retrospectively analyzed and compared with established pathomorphologic descriptions of the disease. The typical findings in contrast-enhanced ultrasound were sub-segmental hyperemia (93/113, 82%) and necrosis with a hyperemic margin (109/113, 96%) in the arterial phase and a washout of liver tissue surrounding necrosis in the late phase (101/113, 89%). Four different sonomorphologic stages of pyogenic liver abscess were identified. Stage I was defined by focal inflammation without necrosis (n = 2); stage II by focal clusters of micro-abscesses appearing to coalesce (n = 41); and stage III by a single cavity with or without capsule (n = 64). Stage IV was defined as numerous small abscesses scattered all over the liver (n = 6). The results indicate that contrast-enhanced ultrasound is suitable for classifying different stages of pyogenic liver abscesses. Knowledge of the described morphologic patterns influences therapeutic decisions and helps distinguish abscesses from other liver masses.
