1 patient with multiple intraosseous ganglion in the tibial plateau was reported. A 54-year-old man presented pain in the right knee. Plain radiographs of the knee showed multiple radiolucency inside the lateral condyle of the right tibial plateau. The histologic examination of the resected cyst wall showed dense fibrous tissues with spotty areas of calcification. Base on the findings, the diagnosis of intraosseous ganglion was made.
