Objective To investigate the diagnostic value of chest multi-slice spiral CT in Poland syndrome.Methods Retrospective collection of chest multi-slice spiral CT images and clinical data of 13 patients with Poland syndrome admitted to Qilu Hospital of Shandong University(Qingdao)from December 2013 to December 2023,analyzing the clinical and imaging characteristics of Poland syndrome.Results Unilateral onset was observed in all patients,with 9 cases on the right side and 4 cases on the left side.Among them,upper limb deformity was present in 3 cases,vagal right subclavian artery in 1 case,absence of middle and lower pectoral bundle or upper and lower pectoral bundle in 13 cases,absence or shortness of pectoralis minor in 12 cases,partial absence of serratus anterior in 1 case,rib and cartilage deformity in 3 cases,sternum deformity in 6 cases,reduced breast glands in 5 cases,and changes in nipple size or position were noted among 6 cases.Chest multi-slice spiral CT can effectively visualize defects of pectoral muscles,rib and rib cartilage deformities as well as reduced breast glands and nipples.Additionally it can potentially identify combined cardiovascular malformations.Multi-plane reconstruction along with volume rendering techniques enable comprehensive evaluation from multiple angles providing a three-dimensional view.Conclusion Chest multi-slice spiral CT is an effective imaging method for the diagnosis of Poland syndrome.
