摘要
目的 研究肝裸区与腹膜后间隙右份的通连关系,并对来源于右肝、肾上腺的较大肿块的CT定位诊断进行初步探讨。方法 回顾性观察38例CT表现,其中右肾旁前间隙积液16例,右肾周间隙积液3例,右肾上腺肿块13例,右肝肿块6例。肿块直径均大于5cm。结果 1.本组右肾前、后筋膜均未在肾上极以上平面显示。2.右肾旁前间隙积液上界未超过肾上极平面。3右肾周间隙内积液向上蔓延至肝裸区。肝裸区附近肝腺肿流入右肾周间隙,而非肾旁前间脓。4.肝裸区肿肿块向下突至右肾周间隙,其优势位置多在门静脉右支平面以上(5/6),常致下腔静脉肝段受压左移(4/6)。5.位于肾周间隙内的右肾上腺肿块向上压迫肝裸区。其优势位置多在门静脉右支平面以下(12/13)。常致下腔静脉肝段受压前移或左前移(9/13、4/13)。结论 肝裸区与右肾周间隙上端相关,而与右肾旁前、后间隙未见沟通。观察该区域肿块的优势位置和与下腔静脉肝段的关系等CT表现,有助于判断其器官来源。
Purpose To study the correlation between the right bare area of the liver (BAL) and the retroperitoneum, and the localization about organ origin of large mass in this region by CT. Methods CT images of 38 patients with pathologic fluid collection in the right anterior pararenal space (RAPS, n= 16) or the right perirenal space (RPS, n= 3) and masses ( > 5cm in diameter) from the right adrenal gland (n= 13) or the right liver (n = 6) were revewed. Results 1 .The right anterior and posterior renal fascias were not found above the superior pole of the right kidney. 2.The fluid collection within RAPS didn't flow upward beyond the plane of the superior pole of the right kidney. 3.The fluid collections within RPS spread up to BAL and the hepatic abscess went into BAL, extending downward into RPS but not RAPS. 4.The right hepatic masses that bulged into RPS compressed intrahepatic segment of inferior vena cave (ISFVC) towards left (4/6) and their predominant position was over the blane of right branch of portal vein (RBPV,5/6). 5.The right adrenal masses compressed against the right liver near BAL and pushed ISIVC forward (9/ 13) or anterointernally (4/13) . Their predominant position was below the plane of RBPV (12/13). Conclusion RPS opens into BAL which is not communicated with the right anterior and posterior pararenal spaces. To observe the predominant position of a msss and the relationship between the mass and ISIVC is helpful in evaluation of the origin of the mass in this region.
