目的：探讨凹陷型锁骨菱形窝的CT表现特点。
方法：对8例（9处）锁骨菱形窝行CT检查，其中1例合并MRI检查；8例均为男性，年龄17～70岁，平均42.5岁。CT均行MPR重建，分别测量病变与锁骨内侧端的距离、病灶大小，同时对缺损区部位、形态、边缘评估。
结果：所有骨质缺损区距锁骨内侧端2 cm内，平均1.3 cm；病灶大小1.05～3.45 cm，平均2.18 cm.8例9处均位于锁骨内侧端后、下缘，右侧5处、左侧4处，其中1例双侧。骨质缺损区内侧端的形态：7处呈“鱼钩征”改变，2处骨质缺损区较小，未出现“鱼钩征”改变。9处后缘皮质线均局限有缺如，近髓腔均有完整硬化边；7处见缺损区较规则条状软组织伸入，2处骨质缺损区较小，未明确显示条状软组织伸入。
结论：凹陷型锁骨菱形窝的CT表现具有一定特征，对该变异的正确诊断及鉴别有较大的价值。 |

| CT manifestation for excavated-type of rhomboid fossa of the clavicle |
|
Abstract:
Objective: To explore the manifestation of CT for excavated-type of rhomboid fossa of the clavicle.
Methods: Nine cases with rhomboid fossaes of the clavicle of 8 patients accepted CT and 1 case added MRI together;all 8 patients were male who aged from 17 to 70 years old with mean age of 42.5 years old;three dimensional reconstruction of all CTs were made,the distance between focus and inside end of clavicle and the size of all focus were measured respectively,then the position,shape,margin of focus were analyzed.
Results: All focuses located near the inside end of clavicle and the distances between focus and inside end of clavicle were lower than 2 cm and the mean value was 1.3 cm,the size of all focuses was from 1.05 to 3.45 cm and the mean value was 2.18 cm. All 9 focuses of 8 patients located in the posterior and nether edge of inside end of clavicle,5 cases located in right and 4 cases located in left side(both right and left side occurred in 1 patient. Seven focuses showed “fishhook sign” and the rest 2 focuses were small and without fishhook shape;the cortex of clavicle of all 9 cases showed local minus and nearly marrow showed integrated sclerotic margin. Regular soft tissue as strip can be seen in 7 focuses and the rest small focuses without the symptom.
Conclusion: CT could show certain characteristics for excavated-type of rhomboid fossa of the clavicle and certain value for its diagnosis and identification. |
