Abstract

Mirror image artifact in ultrasound is not an unusual phenomenon. However, it is rarely seen in thyroid ultrasound because of the natural convexity of the tracheal surface. We report a mirror artifact during thyroid ultrasound in a patient with an excessively collapsible trachea. Minor pressure with the transducer made the trachea surface flat or concave, and then a cyst in the thyroid was mirrored across the trachea, which mimicked an intratracheal cyst. This case illustrates how an unusual collapsible trachea can generate an image that simulates an intratracheal lesion during thyroid ultrasound.

摘要

超声中的镜像伪像并非罕见现象。然而，由于气管表面的自然凸度，在甲状腺超声检查中很少见到。我们报告了1例气管过度可塌陷患者在甲状腺超声检查时出现的镜像伪像。用探头施加轻微压力使气管表面变平或凹陷，然后甲状腺内的一个囊肿在气管对面形成镜像，酷似气管内囊肿。本病例说明了异常可塌陷的气管如何在甲状腺超声检查时产生模拟气管内病变的图像。
