中文摘要 | 腎扁平細胞癌是一種預後很不良的少見癌症,雖然電腦斷層攝影可以很容易辨認腎腫瘤,卻因臨床表徵之非特異性而常被延誤使用及診斷。為此,我們研究本院之病例並報告所得之X光攝影徵象,希望能提早診斷。從28病例之研究中,共發現兩個X光攝影徵象:腎結石分離定義為在兩次素片檢查中,兩個以上腎結石改變其距離或方向;而腎結石變形則定義為腎結石堆積排列成不規則之外形。在28病例中,結石有26例,11例腎盞結石,3例鹿角結石,12例兩者兼具。腎結石分離在11例具有舊片比較者中,發現8例;而腎結石變形則在其餘15例中發現3例。整體之陽性率為39%,但如扣掉2例非結石者,陽性率為42%。從本研究中可知,腎結石分離及變形之X光攝影徵象在腎扁平細胞癌中並非少見,並可能對其較早期診斷有所幫助。 |
英文摘要 | To present the neglected radiographic signs of renal squamous cell carcinoma (RSCC). Twenty-eight cases of RSCC were retrospectively reviewed. Two radiographic signs were elaborated as follows: separating nephroliths sign was defined as change of distance or orientation between two or more renal stones on comparison of two sequential radiographs, while the distorted nephroliths sign was considered positive when a single radiograph showed irregularly marginated stone fragments in a cluster or linear pattern. The incidences of these signs were studied. Renal stones were present in 26 cases, 11 with calyceal stones, 3 with staghorn stone, and 12 with both calyceal and staghorn stones. Separating nephroliths sign was positive in 8 of 11 cases whose previous radiographs were available for compar-ison, and distorted nephroliths sign was seen in 3 of the remaining 15 cases. The overall positive rate was 39% among all cases of RSCC, or 42% when those 2 cases without renal stones were excluded. The separating and distorted nephroliths signs are not uncommon among cases of RSCC and may be useful for its earlier diagnosis. |
