Aim:
To describe the magnetic resonance imaging (MRI) features of spinal plasmacytoma.
Materials And Methods:
The clinical records and MRI findings in six patients (five men, one woman; age range 41-61 years) with histologically proven plasmacytoma of the spine were reviewed. All studies included sagittal T1- and T2-weighted spin-echo sequences and axial T1-weighted spin-echo sequences. Intravenous gadolinium DTPA was administered in four cases.
Results:
MRI showed a characteristic appearances in four cases of low signal intensity curvilinear areas within the vertebra or cortical irregularity.
Conclusion:
Recognition of these imaging features can initiate the appropriate investigation as the commonest differential diagnosis for such lesions is metastasis.Shah, B. K. (2000). Clinical Radiology55, 439-445.
