Periosteal chondroma of the rib: A case report

Figure 2 Magnetic resonance imaging. A: T1-weighted magnetic resonance imaging in the transverse view showed a lobulated tumor on the right side of the thoracic vertebra; B and C: The lesion was bordered by a hypointense rim (arrow) and exhibited long T1 and T2 signals in the sagittal view on T1-weighted (B) and T2-weighted (C) imaging; D: Short tau inversion recovery imaging showed high signal intensity and mottling and patchy long T1 and short T2 abnormal signals within the mass; E: Enhancement was seen predominantly at the periphery of the lesion on post-enhanced images.
