| Abstract | 「要旨」サルコイドーシスの診断ならびに活動性の評価に67Gaシンチは有用とされているが, 今回, 肺門縦隔リンパ節, 特に右傍気管, 両側肺門への67Ga集積所見(Lambda sign)および涙腺, 唾液腺の集積増加所見(Panda sign)に注目し, サルコイドーシスの67Gaシンチグラフィ所見について検討した. サルコイドーシス以外の疾患群で両所見の同時に認められた症例はなくLambda signとPanda signが同時に認められた場合にはサルコイドーシスを積極的に疑う必要があると考えられた. ただし, Lambda像類似所見を呈する症例は他疾患でも存在するため, 胸部X線写真, X線CTとの対比が必要であった. また, Panda signは頸部に放射線照射されていた症例に多く認められた. 「I. はじめに」サルコイドーシスは原因不明の全身性肉芽腫形成性疾患であり, あらゆる臓器に病変が形成され, 多彩な臨床像を呈する. |

| Abstract | [Summary]The lesions of sarcoidosis generally show relatively high Ga-67 uptake and the usefulness of scintigraphy using this agent in the evaluation of lesion activity is well known. In this report, we assessed characteristic uptake of Ga-67 in intra-thoracic lymphnodes, the shape of which resembled the Greek letter Lambda (Lambda sign) and a symmetrical accumulation in bilateral lacrimal and salivary glands which resembled a Panda face (Panda sign) in patients with sarcoidosis. Our review of Ga-67 scans obtained from 15 patients with sarcoidosis and 1,779 patients with other disorders during the past 3 years revealed that the simultaneous presence of both Lambda and Panda signs was specific to patients with sarcoidosis and was not found in patients with various other disorders, although one of these signs might be observed in patients without sarcoidosis. When Lambda-like sign was observed, chest radiogram or CT was necessary for the differential diagnosis of sarcoidosis. Panda sign was observed frequently among patients who had previously received irradiation of the neck. Our results confirmed that sarcoidosis must be suspected when both Lambda and Panda signs were observed. |
