Abstract:
Radiographic, computed tomographic and scintigraphic findings of a patient with separated, multilocular periosteal ganglion are reported. Multiple periosteal cystic masses with calcification in small parts of the cyst walls were demonstrated in the surface of the left tibia by plain radiograms and CT. The accumulations of technetium-99m hydroxymethylene diphosphonate and pentavalent technetium-99m dimercaptosuccinic acid were shown in the calcification in the periosteum and wall of the cyst. Needle puncture revealed that the masses were filled with jelly-like fluid. The masses were diagnosed as multiple ganglionic cysts at the periosteum of the left tibia.
