Solitary bone plasmacytoma


The appearance on non-contrast CT was already suggestive of a solitary bone plasmacytoma.

Histopathology: compatible with plasmacytoma.

The patient also underwent PET, which ruled out additional lesions.

NB: it is important to mention a lumbosacral transitional vertebra in the radiology report, as this has bearing on the level of tumor; in this case, for obtaining a biopsy and centering the radiation beam on the tumor.
