摘要

從1988年8月至1992年7月間，我們回顧性地追查52位罹患有腸骨腰間腔疾病患者的電腦斷層及磁振造影影像，包括30個腫瘤，10個膿瘍，10個血腫，1個尿液囊腫和1個硬脊膜外蜘蛛網膜囊腫。病理生理學上，腸骨腰間腔疾患可歸為三大類：1.病變內生於腸骨腰間腔本身，2.病變起源於脊柱或薦腸骨關節，3.病變源自臨近之後腹腔構造。在我們的經驗中，通常腸骨腰間腔只是疾病散佈之一管道，原發於此之疾病很少。對於疾病的發現與定位，電腦斷層攝影証明已充份足夠，在這個研究系列中，只有2個病例未為電腦斷層偵察出。然而在9位同時有電腦斷層影像及磁振造影病患中，有3位在組織區辨方面，4位在疾病的侵犯範圍方面及5位在是否有脊髓或主要血管侵犯方面，磁振造影被認為是優於電腦斷層攝影。因此對於腸骨腰問腔疾患，磁振造影檢查被推薦作為電腦斷層之一有用的輔助檢查，尤其是當疾患與主要血管或脊柱有密切關連時。

Between August 1988 and July 1992, computed tomography (CT) and magnetic resonance (MR) imaging of pathologies involving the iliopsoas compartment were retrospectively reviewed in a total of 52 patients, including 30 tumors, 10 abscesses, 10 hematomas, 1 urinoma and 1 extradural arachnoid cyst. Pathophysiologically, the iliopsoas disorders could be divided into 3 categories: 1. lesions intrinsic to the iliopsoas compartment, 2. lesions originating in the spinal column or sacroiliac joint, or 3. lesions originating in the nearby retroperitoneal structures. More often the iliopsoas compartment acts only as a conduit for the spread of disease. Primary disorders were rare in our experience. CT is proven to be sufficient enough in lesion identification and localization. Only two cases escaped CT detection in our series. Of 9 patients in whom correlative MR imaging and CT studies were available. MR imaging was judged to be superior to CT in tissue differentiation in 3, in definition of disease extent in 4 and in detection of bone marrow or major vessels involvement in 5. MR imaging is thus suggested to be useful as an adjunct of CT in studying the iliopsoas compartment, especially with disorders closely related to the major vessels or spinal column.
