患者男性40岁，因左颌下区囊性肿物行左颌下腺及囊肿摘除术，术后1个月起左颌下区又出现同样的囊性肿物。查左舌下区浅蓝色肿物，质柔软，穿刺有蛋清样液，该患者左颌下区出现的肿物诊断为
A．左颌下腺囊肿术后复发
B．左舌下腺囊肿口外型
C．左颌下腺摘除术后继发感染
D．左颌下区淋巴结炎
E．左颌下腺导管结石
参考答案：B
解析：口内囊肿穿刺液为蛋清样，口外颌下腺及囊肿均切除后似囊肿复发，说明颌下区囊肿来源于舌下腺囊肿部分，故为舌下腺囊肿口外型。

| When you're a preteen, a huge problem might be that you just have to have a new rock-rap CD, 1 your parents won't give you the money for it. I thought life was so 2 when things like this happened-until September 11, 2001. I was in P.E. when the planes hit the World Trade Center and the Pentagon. As soon as I got home and for weeks after, I saw the disaster 3 on TV. Seeing the innocent people running for their 4 as the debris(瓦砾) started coming down the fire and smoke rose out of the 5 brought tears to my eyes. I couldn't help imagining what the people on the 6 and in the buildings were thinking and going through, not 7 what was going on. I admired the courage of the firefighters who rushed in and risked their own lives to 8 others. It tore my heart apart to watch the 9 looks on the faces of so many people who didn't know if their loved ones were dead or alive while 10 in all the debris. Then it 11 me: All my life I had thought mainly of myself. I had it easy in life and had been taking it all for granted. A feeling of coldness 12 down my back, and I cried just thinking of the possibility that it could have easily 13 to my family. My mom or dad could have been killed like that, and I would never, ever see the m again. I began to evaluate what a real 14 in life was. This disaster 15 me that awful things can happen to anyone at any time. Now when my mom or dad or sister go somewhere, even if it's just 16 the store, I try to remember to tell them that I love them because I know there is a 17 that I may never tell them that 18 . Not getting a new CD is not going to make or 19 my life. I can live with those kinds of problems. But losing someone I love would 20 make my life miserable. 9/11 showed me just what I am. | |||
