We report five patients found to have obvious asymmetry of the psoas muscles on abdominal computed tomography (CT) examination. In all five patients, the upper portion of the psoas muscle was normal, but the lower portion was significantly reduced in size. In no patient was there neurological or other disease that might explain this finding. No patient exhibited signs or symptoms secondary to psoas asymmetry. Asymmetry of the psoas musculature is apparently a benign anatomical variant that may be recognized on CT examination and must be differentiated from pathological conditions.
我们报告了5例在腹部计算机断层扫描（CT）检查中发现腰大肌明显不对称的患者。在所有5例患者中，腰大肌的上部正常，但下部尺寸明显减小。没有患者存在可能解释这一发现的神经或其他疾病。没有患者表现出继发于腰大肌不对称的体征或症状。腰大肌肌肉组织的不对称显然是一种良性解剖变异，可在CT检查中识别，并且必须与病理状况相鉴别。
