摘要
目的:探讨肺错构瘤的CT、MRI征象特点。方法:回顾性分析本院2006年1月至2008年6月经手术病理证实的11例肺错构瘤的CT和MRI的表现,以及3例CT动态增强扫描的特点。结果:肺错构瘤病灶光滑整齐,浅分叶3例,无深分叶征和毛刺征。其中5例有不同程度的钙化,1例为"爆米花"样钙化。4例病灶内有脂肪密度。3例肺错构瘤行螺旋CT动态增强扫描轻度增强(5HU-16HU)。6例T2WI呈高信号中夹杂分隔样低信号。结论:钙化(典型的爆米花样钙化)、脂肪密度是其特征性表现。螺旋动态增强CT扫描和MRI为其诊断和鉴别诊断提供了有价值的信息。
Objective： To investigate the CT and MRI features of pulmonary hamartoma. Methods： The 11 patients with pulmonary hamartoma which were proved surgically and pathologically between 2006-2008, were studied by CT and MRI analyzed retrospectively, and in which 3 hamartomas underwent spiral dynamic enhancement CT. Results： All pulmonary hamartomas had regular and clear margins, without deep lobular-shaped or sentus. Calcification was detected in 5 cases and popcorn-shaped calcium in 1 cases. Detection of fat was found in 4 cases. In the 3 hamartomas of dynamic study, all enhanced lightly （5Hu-16Hu）. MRI revealed septa structures particularly evident on T2-weighted images. Conelusions： Pulmonary hamartoma has regular and clear margins. Popcorn-shaped calcium and detection of fat are the characteristics in CT scan. Dynamic contrast enhancement CT and MRI is helpful in the differentiation of pulmonary hamartoma.
