“肺门感染”是多种病因引起肺门炎症性肿大的 X 线影象总称。由于肺门结构复杂,因体位偏斜或呼吸不相同,常易把正常误为增大(实用儿科学,1973年版,333页);即便明确肺门增大,其性质判定也较困难,上海市结核病中心防治所报告的两组疑为小儿支气管淋巴结结核的316和739例中,误诊率高达59.8%和47.8%(中华儿科杂志9:112,1958和14:181,1965)。 “Hilar infection” is a variety of causes of hilar inflammation of the enlarged X-ray images collectively. Due to the complicated structure of the hilar, skewness or breathing due to body position is not the same, often easy to put the normal error (Practical Science, 1973, 333 pages); even if the hilar enlargement, the nature of the decision is more difficult, Shanghai Misdiagnosis rates were as high as 59.8% and 47.8% for the two groups of 316 and 739 suspected cases of pediatric bronchial lymphadenopathy reported by the TB control center (Chinese Journal of Pediatrics 9: 112, 1958 and 14: 181, 1965).
