“…We add two cases of solitary plasmacytoma in the occipital bone. Both cases showed characteristic radiological appearances similar to those of previously reported cases [5,11,[13][14][15][16][17][18]. They were angiographically hypervascular.…”

“…About a half of solitary plasmacytomas of bone occur in the spine, especially in the thoracic region, and rarely in the skull [2][3][4]. Thirty-five cases of solitary plasmacytoma of the skull have been reported in the literature [2,[4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]; 13 cases occurred primarily in the parietal bone [5-8, 10, 15, 16], 6 in the occipital bone [5,[12][13][14][15], 5 in the frontal bone [5,9,18], 3 in the temporal bone [5,16,17] and 1 in the sphenoid bone [11]. The primary site was not described in the 7 remaining cases [2,4,5].…”

Of 35 cases of skull plasmacytoma reported previously [2,[4][5][6][7][8][9][10][11][12][13][14][15][16][17][18], the CT appearance was described in some [9,10,[15][16][17][18] but the MRI findings in only three [11,17,18]. Six cases located in the occipital bone have been found in the literature.…”

The radiological appearances of two cases of solitary plasmacytoma in the occipital bone are described. One arose in the lateral part and the other in the squama. They showed characteristic radiological features on CT, MRI and angiography. Bone scintigraphy and gallium scintigraphy were also available. Solitary plasmacytoma of the skull is a rare condition and usually occurs in the calvarium. The skull base is an extremely rare site and only four cases have been reported. The literature of solitary plasmacytoma of the skull is reviewed.

“…SPB has been defined by Woodruff et (Table I) CT shows an osteolytic lesion without a sclerotic rim, a hyperdense tumor and homogeneous postcontrast enhancement (2,15,16,19,20). The MR appearance is either isointense, hyperintense or heterogeneous intensity compared with the brain parenchyma on T j-weighted images and homogeneous enhancement by intravenous administration of Gd-DTPA (15,17,19,20,23,24). Osteolytic lesion can usually be identified on X-ray film (14).…”

Solitary plasmacytoma of the skull is very rare and only 35 cases have been reported in the English literature. It remains controversial whether solitary plasmacytoma of the skull is essentially identical with solitary plasmacytoma of bone or not. Solitary plasmacytoma of bone including solitary plasmacytoma of the skull is characterized by a radiologically solitary bone lesion, neoplastic plasma cells in the biopsy specimen, fewer than 5% plasma cells in bone marrow, less than 2.0 g/dl monoclonal protein in the serum when present and negative urine test for Bence Jones protein (monoclonal light chain). Solitary plasmacytoma of bone tends to disseminate or progress to multiple myeloma even as long as 7-23 years after presentation. We report the first case of solitary plasmacytoma of the skull in which both~2-microglobulin for detection of early renal disturbance and neoplastic plasma cell labeling index for detection of DNA synthesis were examined in order to predict the clinical course of solitary plasmacytoma of the skull.
