Chondroblastoma of the temporal bone: CT and MR appearance.
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.
