CT
thorax images in lung window (A-E and H-K) and PET component of an FDG PET/CT
scan demonstrate three synchronous lesions. A solid left upper lobe nodule
(white arrows A and B) was proven to he malignant and was radically treated. In
the right upper lobe there is a lung cyst (blue arrows), which was already
evident on the initial scan (C) and had increased in size over 6 months (D) and
then eventually eloved to a
solid nodule (blue circle, E). Both forms of the right upper lobe lesion the
lung cyst (F) and the solid nodule (G) showed FDG uptake (blue arrowheads). In
the left lower lobe another lung cyst (yellow arrows) was detected (H) which
has also increased in size (J,K). Pleas note that the wall of this cyst has
slightly thickened and mild extent of surrounding ground glass changes became
evident.胸部CT肺窗圖(A-E和H-K)和FDG
PET/CT掃描PET部分顯示同時(shí)存在的3個(gè)病灶。左肺上葉實(shí)性結(jié)節(jié)(白箭A和B)經(jīng)證實(shí)為惡性并進(jìn)行了根治性治療。右肺上葉見(jiàn)一肺囊腫(藍(lán)箭)，最初的掃描顯示已十分明顯(C)， 6個(gè)月后囊腫增大(D)，最終進(jìn)展為實(shí)性結(jié)節(jié)(藍(lán)圈，E)。PET顯示右肺上葉病變表現(xiàn)為肺囊腫(F)和實(shí)性結(jié)節(jié)(G)兩種形式，其中結(jié)節(jié)顯示FDG攝取(藍(lán)箭)。左肺下葉另一肺囊腫(黃箭)(H)也顯示增大(J,K)。注意囊腫壁有輕度增厚，周圍小范圍GGO變明顯。
