Abstract「要旨」 99mTc-リン酸化合物による骨シンチグラフィの鑑別診断学的効用についてX線診断学的に困難を覚えることが多い良性骨腫瘍 (骨腫瘍性疾患を含む) 71例を対象として検討した. 骨シンチグラムの質的情報に絶対性を求めることはできないが, 病巣における放射能集積の3段階表示 (++, +, -) において, 高度異常集積群 (++) として線維性骨異形成 (9例中8例), 動脈瘤様骨嚢腫 (4例中3例), 異常集積が認め難い群 (-) として非骨化性線維腫 (6例中6例), 骨嚢腫 (6例中4例), 内軟骨腫 (4例中3例) および中等度異常集積群 (+) としてエオジン好性肉芽腫 (9例中7例) などの類別化が可能であった. ことに (++) と (-) の群の腫瘍は骨シンチグラム所見が特異的であり, その認識はX線診断を進める過程で, とくに非典型症例の診断に際して, 決定的な鑑別情報としての役割を果し得る. 実例を提示して以上の見解を明らかにした.

Abstract[Summary] Bone scintigraphy with 99mTc-phosphate compounds was evaluated from the analysis of 71 consecutive cases of various benign bone tumors whether the scintigrams could be helpful in their differential diagnosis. The characteristics of the scintigraphic image at the site of bone lesions were noticed as being marked (++), moderate (+) and poor or minimal (-), according to the degree of accumulation of the radioactivity. Fibrous dysplasia (8 among 9 cases) as well as aneurysmal bone cyst (3 among 4 cases) had strong tendency of marked accumulation. Poor or minimal accumulation was observed in almost all of the lesions of nonossifying fibroma including fibrous cortical defect (6 all cases), solitary bone cyst (4 among 6 cases) and enchondroma (3 among 4 cases). Moderate accumulation was said to be non-specific, since it could be encountered in any types of benign bone tumors. But it was noticed that the majority of the bone lesions of eosinophilic granuloma (7 among 9 cases) showed moderate accumulation and the scintigraphic evidence of the skeletal disease appeared to be less extensive than the roentgenogram. These scintigraphic characteristics realized in some benign bone tumors occasionally played an important role in clinical diagnosis, especially in the cases atypical on roentgenographic findings. Several instructive cases whose final diagnosis was strongly linked to the scintigraphic informations were demonstrated.
