Non-excretory plasmocytoma--value of imaging procedures.

We report a case of a 84-year old patient with a non-excretory plasmocytoma. Lacking pathological laboratory values, first diagnostic hints on this rare disease were provided by imaging procedures. Computed tomography and plain radiography surpassed bone scan with 99mTc-diphosphonate compounds in detecting bone associated lesions. According to data in the literature, magnetic resonance imaging and bone marrow scintigraphy seem to be useful in quantifying bone marrow involvement, whereas computed tomography and plain radiography appear to be good tools in detecting localized cortical or spongious lesions in multiple myeloma.
