Case Report (1)
A 45 year-old patient was admitted in July 1996 with a long standing tumor in the backside of the distal 1/3 of the left forearm. The tumor was evident, 6 x 3 cm. wide and attached to deep tissues. He had been seen 4 years before in Costa Rica and X-rays had shown a lithic image located over the distal metaphisis of the left radius bone, with trabeculae, sclerotic rim and involvement of the surrounding soft tissue. An ultrasonograph showed evidence of a possible giant-cell tumor.
Evaluation:
.Radiology (figs. 1 & 2): images similar to those observed four years before. The radiological signs are those of a benign lesion.
The radiological differential diagnosis included aneurysmatic bone cyst, giant-cell tumor, enchondroma...
.Radionucleide scintillography (fig. 3): low uptake images suggestive of a benign lesion and compatible with a giant-cell tumor.
.CT scan (fig. 4): the images show considerable destruction of the posterior wall of the distal third of the radius and this destruction communicates with the soft tissue tumor to form part of the same mass.
.MNR scan (figs. 5 & 6): a clearer picture of the above is shown both with and without contrast.
