| Abstract | 「要旨」神経線維腫症と診断された12例に99mTc DTPAシンチグラフィを施行し, 腫瘍シンチグラフィとしての有用性について検討した. その結果, (1)限局性神経線維腫やびまん性神経線維腫および悪性神経鞘腫には全例99mTc DTPAの集積を認めた. 集積陽性であった最小の神経線維腫は4×3×3cmであった. (2)小腫瘤である皮膚神経線維腫は全例に明らかな集積を認めなかった. (3)カフェオレ色素斑への集積例も認めなかった. (4) 67Gaシンチグラフィが施行された2例では, 99mTc DTPAの集積が陽性であった神経線維腫や悪性神経鞘腫いずれにも67Ga citrateの異常集積を認めなかった. 以上より, 99mTc DTPAシンチグラフィは神経線維腫症において, 皮膚神経線維腫のような小病変の描出は不可能であるが, 限局性神経線維腫やびまん性神経線維腫の腫瘍シンチグラフィとして有用であるといえる. また悪性神経鞘腫症例の転移巣の検索にも有用と考える. |

| Abstract | [Summary] Technetium-99m DTPA scintigraphy was performed in 12 cases with neurofibromatosis, to evaluate the utility for tumor scintigraphy. The results were as follows: (1) Tc-99m DTPA accumulated to all lesions of localized neurofibroma, pachydermatocele and localized malignant schwannoma. The minimal tumor of these lesions was 4×3×3 cm in size. (2) No tracer uptake was demonstrated in small tumors, such as cutaneous neurofibroma. (3) No tracer uptake was noted in Cafe-au-lait spots. (4) Ga-67 citrate did not accumulate in the all cases of neurofibroma and malignant schwannoma performed with Ga-67 scintigraphy. These results suggest that Tc-99m DTPA scintigraphy is useful to detect localized neurofibroma, pachydermatocele or malignant schwannoma, although it is not available to evaluate small lesion like as cutaneous neurofibroma. This scintigraphy may be helpful to detect metastatic foci of malignant schwannoma. |
