“…Our case showed similar MRI appearances to the thoracic chordoma described by Taki et al [4] and to chordomas described in other sites [5,6], being of predominately low signal intensity on T1-weighted images and of high signal intensity on T2-weighted images. Haemorrhagic necrosis, seen inferiorly in the mass, is a common finding in chordomas.…”

A case of a chordoma in the thoracic spine is presented. This is a very rare tumour in this location and should be considered in the differential diagnosis of any posterior mediastinal mass. The appearances on CT and MRI were similar to chordomas described in other locations. On T2-weighted images septae of low signal intensity radiated throughout the large high-signal mass. This feature may be of use in differentiating chordomas from other posterior mediastinal masses.

“…The differential diagnosis should include chordoma, which is also low-grade malignant tumor, in cases of sacral solitary plasmacytoma. The median age of incidence of chordoma is slightly higher than solitary plasmacytoma, and the imaging of chordoma often show complete bone destruction, sometimes with remaining bone, but seldom causes multilocular change ( 20 ).…”

ObjectiveTo describe the imaging features of pelvic solitary plasmacytoma and to correlate them with the pathologic grade.Materials and MethodsA retrospective study was performed on the imaging features of 10 patients with a histological diagnosis of pelvic solitary plasmacytoma. The imaging studies were assessed for bone expansion, cortical destruction, signal intensity/density of soft tissue mass and enhancement manifestations, which were then correlated to the pathologic grade.ResultsThe imaging features of pelvic solitary plasmacytoma revealed 3 different types: multilocular type (n = 5), unilocular type (n = 2) and complete osteolytic destruction type (n = 3) on computed tomography and MRI. Pathologically, the tumors were classified into low, intermediate and high grades. Features such as multilocular change, perilesional osteosclerosis, slight expansion, local bone cortex disruptions and masses inside bone destruction, often suggest a low-grade solitary plasmacytoma; complete osteolytic destruction, huge soft tissue mass, and osseous defects imply a higher pathologic grade.ConclusionPelvic solitary plasmacytoma has various imaging manifestations, while a slight expansile osteolytic feature with multilocular change or homogeneous enhancement highly suggests its diagnosis. The distinctive imaging features of pelvic solitary plasmacytoma are well correlated to the pathologic grade.
