摘要
目的:探讨腹膜假粘液瘤的CT表现及其病理基础。方法:回顾性分析6例经手术病理证实的腹膜假粘液瘤的CT表现,并与手术病理对照分析。结果:6例患者均为腹腔内弥漫性病变,CT表现为粘液样腹水伴有分隔,囊性包块,肝脾表面扇形压迹,肠管受压移位,腹膜外囊性包块。显微镜下可见大粘液池伴血管充血和慢性炎性细胞浸润,粘液中有腺上皮细胞。结论:CT能反映腹膜假粘液瘤的病理学特征。
Objective：To investigate the correlation between CT findings and their pathology basis of pseudomyxoma peritonei. Methods.. Retrospectively reviewed the CT images of 6 patients with histologically proven pseudomyxoma peritonei. Correlative study of CT and pathological settings was carried out. Results：Six patients who had diffuse peritoneal lesions were characterized by mucinous ascites, low-attenuation masses,and scalloping hepatic margin on CT. Areas of septa and calcification were seen within ascites and masses. Pseudomyxoma peritonei extended into extraperitoneal space. Pathological examination revealed abundant extracellular mucin and exfoliated tumor cells. Conclusion： Pseudomyxoma peritonei is difficult to diagnose clinically. However, the pattern of accumulation of disease is predictable and can be recognized on CT.
