多发结核球的诊断与鉴别诊断之影像学分析

目的探讨多发结核球的影像学特征,提高对多发结核球的影像学诊断准确率。方法对13例经病理证实的肺内多发结核球的影像学表现进行回顾性分析。结果多发结核球仍以上肺的尖后段、下叶的背段为好发。CT是提高多发结核球诊断准确率的有效手段之一,好发部位、病灶内小斑点钙化或靠近边缘的条弧状钙化、偏心性靠近边缘（近肺门侧）的半月形空洞、胸膜肥厚,是多发结核球的重要诊断依据。结论多发结核球主要与肺转移癌相鉴别,因两者在影像形态学上有诸多相似之处,当发现肺内多发结节灶时,容易首先想到肺转移癌,只要认真辨析,识别其中具有一定特征性的影像学表现,结合临床资料是可以作出正确的影像学诊断的。

Multi-ball TB image analysis of diagnosis and differential diagnosis

Objective The portrait purpose is to increase the accuracy of multiple images of the diagnostic imaging by exploring imaging characteristics of multiple tuberculoma.Methods The method is to do retrospective analysis to multiple pulmonary tuberculosis image of the ball which is pathologically confirmed by 13 cases. Results The result is that multiple tuberculoma is often in the posterior part of the upper lung and the back of the under lung. CT is one of the means to improve more accurate diagnosis of TB-effect. Multiple parts, calcified lesions, small classes, or Arc calcification close to the edge, half-moon cavities eccentricly approaching the edge （near the lung side hilun ） and fleshy pleura are the very important diagnosis bases for multiple tubereuloma.TB diagnosis based on the ball.CT is one of effective means to improve the multi-ball TB diagnostic accuracy. Good site,lesions Calcification small point, or Arc calcification close to the edge, the hollow half-moon close to the edge of eccentricity （near side of the hilar） and pleural thickening, are muhi-TB diagnoses based on the importance of the ball.Conclusion Conclusion Multiple tuberculomas were mainly identified with metastatic carcinoma of the lung, because both of them have many similarities on image morphology. When multiple nodules are found in lung, metastatic carcinoma of the lung will be easily thought of at first. As long as serious analyses are done and characteristics of the image are carefully identified, right diagnoses can be made combined with clinical datum.
