| Abstract | 「要旨」 201Tl心筋シンチグラフィ施行時に縦隔に異常集積を認め, 手術により悪性胸腺腫と診断された2例を経験した. 1例は負荷心筋シンチグラフィ時に偶然発見され4時間後の遅延イメージでより鮮明に描出され, 67Gaシンチグラフィでも著明な異常集積がみられた. 他の1例は67Gaシンチグラフィでは集積がみられなかったが, 201Tlシンチグラフィでは陽性描画された. 2症例とも胸部単純写真では縦隔陰影に異常がみられず, 201Tlシンチグラフィが悪性胸腺腫の診断に有用であった. 「I. はじめに」 Thallium-201 Chloride (以下201Tl) は心筋イメージング製剤として広く用いられ, 特に虚血性心疾患の診断には201Tlシンチグラフィは欠かすことのできない検査法となってきた. 一方, 201Tlは腫瘍親和性をもった放射性医薬品として, その有用性が報告されてきている. |

| Abstract | [Summary] We present two cases of malignant thymoma which showed a remarkable accumulation of thallium-201 chloride on myocardial scintigraphy. A 69 year-old man underwent stress 201Tl scintigraphy to evaluate myocardial ischemia and abnormal accumulation of thallium activity was observed in the anterior mediastinum by chance. It was more clearly visalized on delayed image. Moreover, abnormal uptake of 67Ga citrate was also observed in the same region. In another 68 year-old woman, there was high uptake on 201Tl scintigraphy, but no abnormal uptake using 67Ga. The diagnosis of malignant thymoma was confirmed by operation in each patient. These two cases had no abnormality in the mediastinum on the chest X-ray film and one of them had no uptake of 67Ga, 201Tl scintigraphy was more useful to detect malignant thymoma. |
