Abstract
We report a case of chondroblastoma of the temporal bone occurring in a 28-year-old man. Chondroblastoma is a benign bone tumor that classically occurs in the epiphysis of long bones in young people. The temporal bone is an unusual location. Computed tomography (CT) showed a mass in the temporal bone with bone erosion and destruction. On magnetic resonance (MR) imaging, the tumor showed isointensity to the brain on T1-weighted (T1W) images, heterogeneous high-signal intensity on short-inversion-time inversion recovery (STIR) images, and the central region was more hyperintense than the marginal region. On a dynamic gadolinium-enhanced fat-suppression study (dynamic study), the central region of the tumor showed a gradual increase in intensity toward the center. Pathologically, the central region of the tumor contained abundant cartilaginous material.
