We report a case of 43-year-old female with a periosteal ganglion arising in the right radius. Plain radiographs showed thick and sparse spicula with shallow and irregular cortical erosion, which suggested periosteal ganglion. Magnetic resonance (MR) imaging revealed a well circumscribed homogeneous lesion with low signal intensity on T1-weighted images and high signal intensity on T2-weighted images. No apparent enhancement observed after gadolinium injection suggested that the lesion was cystic. At operation, gelatinous material was removed together with the spicula, the surface of the cortex and the overlying periosteum. There was no clinical evidence of recurrence after three years of surgical treatment. MR imaging was thought to be useful to confirm the diagnosis of periosteal ganglion.
