【摘要】：选取31例经手术证实为阑尾粘液囊肿的病例,对其影像表现进行回顾性分析。结果阑尾粘液囊肿在CT上表现为右下腹部紧邻回盲部的大小不等的圆形、椭圆形或长管形的囊性病灶,部分病灶内可见线样分隔影,伴或不伴囊壁钙化,增强部分病灶囊壁呈轻度强化;MRI冠状面上位于髂肌和腰大肌形成的"V"字间隙内,呈均匀或不均匀长Tl长T2信号影,囊肿壁光整,部分囊壁可见线样强化,病灶内容物未见强化,病灶周围结构清晰,邻近肠管均有不同程度受压、粘连。阑尾粘液囊肿的影像表现有一定的特征性,正确认识该病的影像特征,有助于提高术前诊断符合率。
[Abstract]:The imaging findings of 31 cases of appendiceal mucocele confirmed by operation were analyzed retrospectively. Results on CT scan, the mucocele of appendicitis presented as a circular region adjacent to the ileocecal part of the right lower abdomen. In the oval or long tubular cystic lesions, linear septum could be seen in some lesions, with or without calcification of the cyst wall, and the enhancement of the cystic wall of some lesions was mild enhancement. The coronal plane of MRI was located in the "V" space between iliac muscle and psoas major, with uniform or uneven long T _ 2 signal intensity, smooth cyst wall, linear enhancement in part of cyst wall, and no enhancement in the contents of the lesion. The surrounding structure of the lesion is clear, the adjacent intestinal duct is compressed to varying degrees and adhesions. The imaging manifestations of the mucocele of the appendix have some characteristics. It is helpful to understand the imaging features of the disease correctly and to improve the diagnostic accuracy before operation.

【正文快照】： 阑尾粘液囊肿(AMC)临床不常见,手术切除的阑尾标本中约0.43%属此[1]。阑尾粘液囊肿误诊率极高,高达89.7%[1]。本病多属良性,但如果破裂可种植于腹膜,继发腹膜粘液瘤,术后易复发,具有低度恶性,降低患者的生存率。故术前做出正确诊断有助于术前正确评估病情,选择最佳手术入路,防
