| Abstract | 「要旨」CTスキャンで偶然発見された副腎腫瘍の診断における副腎皮質シンチグラフィの有用性をretrospectiveに検討した. 対象は, 6例の担癌患者を含む29例で明らかな副腎皮質機能異常を認めなかった. 腫瘍側に集積亢進を示したのは13例で, 担癌患者は含まれなかった. このうち, 手術された9例は全例良性, 経過観察された1例は大きさの変化を認めず, 残りの3例はその後の検査が施行されなかった. 両側副腎の集積に左右差を示さなかった癌患者2例を含む6例で経過観察で大きさの変化がなく, 2例が手術で良性腫瘍と判明し, 1例はその後の検査が施行されなかった. 腫瘍側に集積の低下を示す症例は7例で, そのうち4例が悪性腫瘍の転移であった. その他は, 2例が嚢腫, 1例は経過観察で大きさの変化を認めなかった. 副腎皮質シンチグラフィは, 集積亢進を示す良性副腎腫瘍と集積低下を示す悪性腫瘍の転移や嚢腫などの鑑別に有用であった. |

| Abstract | [Summary] To assess the nature of adrenal mass incidentally discovered on computed tomography, adrenocortical scintigraphy with I-131-6β-iodomethyl-19-norcholest-5(10)-en-3β-ol (I-131 Adosterol) in 29 patients was retrospectively reviewed. All patients had no clinical symptoms and biochemical evidence of adrenal hyperfunction. Six of them had extraadrenal malignancy. Increased tracer uptake on the side of adrenal mass was observed in 13 patients (concordant group) : cortical adenoma in 8, macronodular hyperplasia in 1, no growing tumor in 1, and no further examination in the remaining 3 patients. No cancer patients were included in the concordant group. Symmetric uptake was seen in 9 patients (symmetric group) : 1 cortical adenoma and 1 ganglioneuroma, 6 no growing tumor (two of them had malignancy), and no further examination in 1 patient. Decreased uptake were shown in 7 patients (disconcordant group) : metastasis in 4, adrenal cyst in 2, and no growing tumor in 1. Adrenocortical scintigraphy was helpful in distinguishing benign functioning adrenal masses from non-functioning adrenal masses such as metastatic tumor and cyst. |
