摘要

研究目的:炎性假瘤是一种罕见的良性肿瘤，可发生在身体的各个部位。由于其罕见的发生和组织学的多样性，放射学资料是异质和有限的。病例描述:我们报告一例71岁男性大网膜炎性假瘤。对比增强超声灌注模式显示动脉期均匀等回声增强，实质期冲洗现象，模拟腹膜癌。结论:炎性假瘤是一种罕见但重要的良性鉴别诊断选择，当考虑恶性疾病时。对比增强超声有助于识别重要组织，为随后的组织学检查进行靶向活检，这对于排除恶性肿瘤是必不可少的。

Inflammatory Pseudotumor of the Omentum in Contrast-enhanced Ultrasound.

Aim of the study: Inflammatory pseudotumor is a rare benign tumor that can occur at various body sites. Due to its rare occurrence and histological variety radiological data is heterogeneous and limited.

Case description: We present a case of a 71-year-old man with inflammatory pseudotumor of the omentum. Contrast-enhanced ultrasound perfusion pattern showed homogeneous, isoechoic enhancement in the arterial phase with a washout phenomenon in the parenchymal phase, mimicking a peritoneal carcinomatosis.

Conclusions: Inflammatory pseudotumor represents a rare, but important benign differential diagnostic option when considering a malignant disorder. Contrast-enhanced ultrasound is helpful in identifying vital tissue for a targeted biopsy for subsequent histological examination that is essential for the exclusion of malignancy.
