Abstract

Introduction: The sternalis muscle is a rare muscular variation of the anterior thoracic wall. When present, it can confuse the radiologists as a breast mass on mammograms and pose as a challenge and opportunity at the same time for surgeons during mastectomies or breast augmentation procedures. This study aims to investigate the frequency and anatomy of the sternalis muscle on a large Turkish sample. Material and Methods: Following ethical approval, the presence and anatomy of the sternalis muscle was investigated on thoracic computed tomography (CT) scans of 8408 patients. Results: The sternalis muscle was present in 263 (3.1%) patients. The presence of the muscle was unilateral on the right side in 104 (39.5%), unilateral on the left side in 96 (36.5%), and bilateral in 63 (24%) patients. In 326 hemithoraces, Type 1, Type 2, and Type 3 sternalis muscles were observed in 79.2%, 14.4%, and 6.4% of the patients, respectively. Discussion and Conclusion: The frequency of the sternalis muscle among the Turkish population was relatively lower compared to the previous studies on different ethnicities. In addition, CT provides a detailed evaluation of the muscle.

计算机断层扫描鉴定活体胸骨肌

简介：胸骨肌是胸前壁一种罕见的肌肉变异。如果存在，它可能会将放射科医生混淆为乳房X光检查中的乳房肿块，并在乳房切除术或隆胸手术中对外科医生构成挑战和机遇。本研究旨在研究土耳其大样本胸骨肌的频率和解剖结构。材料和方法：在获得伦理批准后，对8408名患者的胸部计算机断层扫描（CT）进行了胸骨肌的存在和解剖研究。结果：263例（3.1%）患者存在胸骨肌。104例（39.5%）患者右侧单侧存在肌肉，96例（36.5%）患者左侧存在肌肉，63例（24%）患者双侧存在肌肉。在326例半胸中，分别有79.2%、14.4%和6.4%的患者观察到1型、2型和3型胸骨肌。讨论和结论：与先前对不同种族的研究相比，土耳其人群中胸骨肌的频率相对较低。此外，CT提供了对肌肉的详细评估。
