问题 单项选择题 A1型题

一男性年轻人右大腿下端肿痛2个月余。X线片见股骨下端有境界不清的骨质破坏区,有放射状阴影,两端可见骨膜三角。最可能的诊断是()

A.骨髓炎

B.骨结核

C.骨肉瘤

D.骨巨细胞瘤

E.骨转移癌

答案

参考答案:C

解析:成骨肉瘤是高度恶性的骨肿瘤,多见于年轻人,多发生于骨骺生长最活跃的部位,如股骨下端、胫骨或腓骨上端和肱骨上端。成骨肉瘤生长迅速,临床表现主要为疼痛,由间歇发作转为持续疼痛;关节功能障碍;局部皮肤发热,浅静脉怒张。X线显示干骺端骨破坏,有大量的肿瘤样骨。当肿瘤侵袭超过骨组织后,可掀起骨膜,形成骨膜下的三角状新骨,称为Codman三角,有"日光射线"征象。

Once upon a time, there was an island where all the feelings lived: Happiness, Sadness, Knowledge, and all of the others, including Love. One day the feelings were told that the island would sink, so all built boats and left, except Love. Love was the only one who stayed. Love wanted to hold out(坚持) until the last possible moment.

When the island had almost sunk, Love decided to ask for help.

Richness was passing by Love in a big boat. Love said, “Richness, can you take me with you?”

Richness answered, “No, I can’t. There is a lot of gold and silver in my boat. There is no place here for you.”

Love decided to ask Vanity(虚荣心) who was also passing by in a beautiful ship.“Vanity, please help me!”

“I can’t help you, Love. You are all wet and might damage(破坏) my boat, “Vanity answered.

Sadness was close by so Love asked, “Sadness, let me go with you.”

“Oh…Love, I am so sad that I need to be by myself!”

Happiness passed by Love, too, but she was so happy that she did not even hear when Love called her.

Suddenly, there was a voice, “Come, Love, I will take you.”It was an elder. So thankful and happy, Love even forgot to ask the elder where they were going. When they arrived at dry land, the elder went her own way. Realizing how much was owed(欠) the elder, Love asked Knowledge, another elder, “Who helped me?”

“It was Time, “Knowledge answered.

“Time?”asked Love.“But why did Time help me?”

Knowledge smiled with deep wisdom(智慧) and answered, “Because only Time is able to understand how valuable(珍贵的)Love is.”
