Abstract

Purpose: The purpose of this study was to describe the MR findings of chondroblastoma with pathologic correlation. Method: In 22 patients with pathologically proven chondroblastoma, MR signal characteristics were correlated with pathological findings. Results: On T2-weighted images, 12 (55%) lesions were hyperintense with hypointense areas in 9 lesions, whereas 10 (45%) Were hypointense. Therefore, 19 of 22 (86%) lesions with pathologic correlation had hypointense areas entirely (n = 10) or partly (n = 9) on T2- weighted images. On gadolinium-enhanced images, 13 (59%) lesions showed lobular enhancement and 9 (41%) showed marginal and septal enhancement. Low signal intensity on T2-weighted MR images was most strongly associated with an abundance of immature chondroid matrix, hypercellularity of the chondroblasts, calcifications, and hemosiderin on histology. Conclusion: Chondroblastoma was found to show hypointense portions on T2-weighted images. Signal intensity on TI- and T2-weighted MR images in chondroblastoma was dependent on the amounts of histopathological components.
