| Abstract | 「要旨」99mTc-リン酸化合物による骨シンチグラフィにおいて, 悪性腫瘍骨転移巣のRI集積低下または欠損("Cold" lesion)を認めた27症例32か所について検討した. 原発病巣は肺癌(11/27, 41%)が最も多く, そのほか乳癌, 子宮癌, 前立腺癌, 肝癌, 食道癌, 甲状腺癌, 原発不明癌であった. "Cold" lesionは骨盤(8/32, 25%), 肋骨(7/32, 22%), に多く, その他頭蓋, 胸椎, 胸骨, 腰椎, 脛骨にみられた. 原発病巣と"Cold" lesion出現部位との関係は, 肺癌で肋骨に多くみられたが(6/12, 50%), そのほかは特定の傾向はなかった. "Cold" lesionを周囲のRI集積程度により, "Cold" lesionのみと, "Cold" lesion周囲にHot lesionを伴ったものとに分類した. "Cold" lesionのみは, 胸椎と腰椎(7/12, 58%)に多いが, 頭蓋, 胸骨, 骨盤など扁平骨(2/12, 16%)には少なかった. 逆に"Cold" lesion周囲にHot lesionを伴ったものは, 頭蓋, 胸骨, 骨盤など(14/20, 70%)に多く, 胸椎と腰椎(1/20, 5%)には少なかった. "Cold" lesion部位の骨X線写真所見は, Osteolytic所見が多いが(26/32, 81%), 明らかな異常所見を指摘できない場合もあった(6/32, 19%). |

| Abstract | [Summary] Bone scintigraphy with 99mTc-phosphorous compound is very useful in the detection of early bone metastasis from malignant tumor. In general, bone metastasis is noticed as a hot lesion on the scintigram. But recently, bone metastasis with decreased uptake is sometimes reported. We also experienced such cases, so we would like to present them and to discuss their causes. "Cold" lesions on bone scintigraphy were seen in twenty-seven cases of malignant tumor with bone metastasis, while four cases revealed two or more lesions. Primary lesions were lung cancer (11/27, 41%), breast cancer (3/27, 11%), and so on. "Cold" lesions were located on the pelvis (8/32, 25%), rib (7/32, 22%), and on the other sites. "Cold" lesions not surrounded with hot lesion were seen on the thoracic spine and lumbar spine (7/12, 58%), but "Cold" lesions surrounded with hot lesion were observed on the skull, sternum, and pelvis (14/20, 70%). Osteolytic changes on the radiograph were seen on twenty-six sites (26/32, 81%), but on the others no abnormality was noticed (6/32, 19%). |
