To characterize the computed tomography (CT) imaging findings in patients with pulmonary chondroma.
We examined CT imaging findings of eight patients with histopathologically verified pulmonary chondroma. We assessed the location, size, shape, margins, amount of calcification, calcification pattern, and attenuation on precontrast and enhancement CT.
All patients exhibited solitary, mildly lobulated pulmonary masses, which were located in the right lung in four cases and the left lung in four cases. The mean lesion size was 3.7 cm (range 0.9-10.7 cm). All eight tumours had a well-defined margin. On plain CT images, seven of the cases (87.5%) showed a mass with varying degrees of calcification, which included strip-like punctate (n=5) and ring (n=2) patterns. One patient with a large lesion (10.7 cm) showed chest wall adhesion. On contrast-enhanced CT images, all lesions demonstrated slight inhomogeneous enhancement ≤14 HU.
CT is the reference standard diagnostic technique for locating pulmonary chondroma. In most cases, CT findings show some characteristics that are important in the diagnosis, surgical planning, and follow-up of the tumour.
描述肺软骨瘤患者的计算机断层扫描（CT）影像学特征。
我们检查了 8 例经组织病理学证实的肺软骨瘤患者的 CT 影像学表现。我们评估了病变的位置、大小、形状、边缘、钙化程度、钙化模式以及平扫和增强 CT 的衰减。
所有患者均表现为孤立性、轻度分叶状肺肿块，4 例位于右肺，4 例位于左肺。病变平均大小为 3.7cm（范围 0.9-10.7cm）。8 个肿瘤均有明确的边界。平扫 CT 图像上，7 例（87.5%）显示不同程度的钙化肿块，包括条带状点状（n=5）和环形（n=2）。1 例大病灶（10.7cm）患者有胸壁粘连。增强 CT 图像上，所有病灶均表现为轻微不均匀强化，≤14HU。
CT 是定位肺软骨瘤的参考标准诊断技术。在大多数情况下，CT 表现具有一些特征，对肿瘤的诊断、手术计划和随访很重要。
