Chest x-ray 如下,請問診斷是?
Hint: 請對照看以下另一位正常小 baby 的 CXR:
答案應該知道了吧?
對,就是 DiGeorge Syndrome。 請仔細看病人的 CXR:mediastinum 是窄的,因為少了 thymus!The DiGeorge syndrome is an example of a selective T-cell deficiency caused by the failure of development of the third and fourth pharyngeal pouches.
These pouches give rise to the following structures:
- thymus
- parathyroid
- saortic arch
- portions of the lips and ears
