Adamantinoma of Tibia in a 32-year-old man
The MR findings showing the typical features of this relatively rare bone tumor. It is essentially an intracortical tumor extending both to the medulla and to the soft tissues. The behavior can be unpredictable. Both the radiological and the histological diagnosis may be difficult and misleading mostly due to the rarity of this particular neoplasm. Tibia is by far the commonest location. This particular case had originally been diagnosed as a synovial sarcoma invading bone. A careful radiological examination might have shown conclusively that this was not a tumor of soft tissue. A pathologist, unaware of the radiological findings and confronted with a misleading clinical diagnosis of "soft tissue sarcoma" may well diagnose this tumor as a synovial sarcoma, another "biphasic tumor".
