The authors report a case of chondroblastoma in the unusual location of the temporal bone. CT findings do not differ dramatically from other reports: the lesion appeared as a soft-tissue density mass in the right temporal bone, with bony destruction and thinning of cortical margins. MR findings are more rare: on coronal T1-weighted images the lesion appeared as a mass, isointense to gray matter, centered in the right petrous bone; on axial T2-weighted images, as a mixed-intensity signal mass. They conclude that MR is an accurate indicator of the location and extension of the tumor, but that CT gives more specific information regarding bone involvement.
作者报告了一例发生在颞骨这一不寻常部位的软骨母细胞瘤病例。CT表现与其他报告相比并无显著差异：病变在右侧颞骨表现为软组织密度肿块，伴有骨质破坏和皮质边缘变薄。MR表现则较为少见：在冠状位T1加权像上，病变表现为一个肿块，与灰质等信号，位于右侧岩骨中心；在轴位T2加权像上，表现为一个混合信号强度的肿块。他们得出结论，MR是肿瘤位置和范围的准确指标，但CT能提供有关骨质受累的更具体信息。
