Abstract

BACKGROUND AND OBJECTIVES

The aim of the study was to describe the radiological anatomy of the -a structure localized at the floor of the supraspinatus fossa, just below the true suprascapular notch. In sonographic examination, it may imitate the suprascapular notch leading to misidentification of these structures.

METHODS

Ultrasound assessment of the suprascapular notch region was performed in 100 patients who underwent chest CT due to other indications. The presence of the suprascapular notch and the was evaluated together with their maximal width and depth using both techniques. The correlation between the dimensions of these two notches was assessed.

RESULTS

The was recognized in 82 patients. In four of them the suprascapular notch could not be visualized in ultrasound due to obscuring clavicle. In all cases the contained a small artery. In comparison to the suprascapular notch, the was significantly narrower and shallower, except for 10 cases with vestigial suprascapular notch where the was the only hollow in this region. The dimensions of both structures did not correlate with each other. Finally, the did not present any significant asymmetry (p=0.1185) or sexual dimorphism (43 women vs 38 men, p=0.2025).

CONCLUSIONS

The is a hollow for nutrient vessels that can be mistaken for the regular suprascapular notch in cases of difficult sonographic navigation.

摘要

背景与目的

本研究旨在描述位于肩胛上窝底部、真肩胛切迹下方的 -a 结构的影像学解剖。在超声检查中，它可能模仿肩胛切迹，导致这些结构的误诊。

方法

对因其他原因行胸部 CT 检查的 100 例患者进行肩胛切迹区域的超声评估。使用两种技术评估肩胛切迹和 -a 的存在及其最大宽度和深度。评估这两个切迹之间的相关性。

结果

在 82 例患者中识别出 -a。其中 4 例由于锁骨遮挡而无法在超声中显示肩胛切迹。在所有情况下，-a 内均有一条小动脉。与肩胛切迹相比，-a 明显更窄、更浅，除了 10 例存在发育不全的肩胛切迹，在这些情况下，-a 是该区域唯一的凹陷。这两个结构的尺寸彼此之间没有相关性。最后，-a 没有表现出任何明显的不对称（p=0.1185）或性别二态性（43 名女性与 38 名男性，p=0.2025）。
