The authors present three cases of histologically proved synovial sarcoma. CT is useful in assessing erosive or destructive changes in bone, and in demonstrating calcifications. MR characteristics are nonspecific; calcifications within these tumors can be missed on MR. MR can help to assess tumor extension, vascular invasion, and hemorrhage within the tumor.

Though seen with diminishing frequency, psoas abscesses of tuberculous origin are usually secondary to vertebral lesions. The absence of radiologically detectable bone lesions should not exclude the diagnosis, however, as these abscesses can be associated with sub-ligamentary spinal lesions. A case is reported of a psoas abscess of tuberculous origin revealed by a voluminous retroperitoneal mass, without visible signs of any bone lesion. The results of the different examinations conducted are presented.
