摘要
目的探讨胸壁错构瘤的MSCT征象。方法收集5例经手术病理证实的胸壁错构瘤患儿资料,结合文献分析其病理起源、临床特点与MSCT表现。结果 4例为单发病变,1例为双发病变。共6处病变,其中位于左后胸壁3处,位于左前胸壁、右后胸壁、右侧胸壁各1处,均起源于肋骨。CT均表现为肋骨膨胀性改变,局部形成凸向胸腔内或胸腔外的不均匀密度肿块,边界清楚,内见高密度骨化或钙化影,增强后肿块部分呈轻-中度强化。结论胸壁错构瘤的MSCT表现具有一定特征性,可很好地显示病变起源、大小、受累肋骨的数量及邻近组织结构情况。
Objective To investigate MSCT manifestations of chest wall hamartoma.Methods Five cases of pathologically proved chest wall hamartoma were collected.The origination,clinical features as well as manifestations on MSCT were analyzed retrospectively.Results Four cases had single lesion,while one case had two lesions.Among totally six lesions proven to be originated from rib bones,three located in left posterior chest wall,one in left anterior,one in right posterior,and the rest one in right lateral chest wall.All lesions presented as expansive bone destruction of the rib and heterogeneous density soft tissue masses containing calcifications or ossifications inside with a well defined boundary growing towards extra or intra chest cavity.Mild to moderate enhancement was observed after administration of contrast medium.Conclusion CT manifestations of chest wall hamartoma have some characteristics.MSCT can show the origination,location,size and involved ribs as well as conditions of adjacent structures of chest wall hamartoma.
