Pulmonary Atelectasis*

The authors have experienced a case of entire lung collapse on the right side which appeared after upper abdominal operation under endotracheal general anesthesia. It has been rarely reported in the literature.

Accessory fissures serve not only as natural barriers against infection but also help in localizing any focal pulmonary parenchymal diseases and in distinguishing pleural from parenchymal diseases. Knowledge of these fissures might be useful in differentiating unusual forms of atelectasis or consolidation occuring adjacent to the fissure. Left minor fissure (LMF) is a kind of unusual accessory fissures of the left lung, which separates adjacent segments of the upper lobe as clefts of various depths lined by two layers of visceral pleura. In this study, 4 cases of LMFs found in the left upper lobe during a routine dissection of 36 cadavers were observed. Of the 4 cases, 3 cases were true LMFs which located between the anterior segment of the upper lobe and superior segment of lingula, and 1 case was considered as left azygos fissure. Among the true LMFs, 2 LMFs coursed horizontally and 1 LMF coursed upward obliquely along the costal surface. The depth of LMFs was 0.5~1.2 cm and the length was 5~8 cm.

The characteristic radiographic and CT findings of Iobar atelectasis are well known. However, Iobar atelectasis is a dynamic process, and atypical presentations may occur due to a number of different causes. Familiarity with the various typical and atypical radiographic findings of Iobar atelectasis is important for correct diagnosis. The aim of this manuscript is to illustrate the spectrum of radiographic findings of Iobar atelectasis and to correlate the radiographic findings with the CT findings. The review will illustrate examples of typical and atypical Iobar atelectasis, including combined Iobar atelectasis, peripheral Iobar atelectasis, migrating Iobar atelectasis, rounded atelectasis involving the entire lobe and Iobar atelectasis mimicking paravertebral and mediastinal masses.

Asthma is a common disease in children. However, CT findings in childhood asthma are rarely reported. Several authors reported CT findings in adult: bronchial wall thickening, bronchiectasis, mucoid impaction, acinar pattern, lobar or subsegmental collapse, air-trapping, or emphysema. We have studied three cases of HRCT findings in childhood asthma, and HRCT findings included bronchial wall thickening, bronchial dilatation, patchy air-space consolidation, ill-defined acinar nodules, centrilobular nodule, subsegmental atelectasis, and multiple focal areas of lobular air-trapping or mosaic perfusion pattern. These above findings are similar to those of adult. A Brief review of related literature was presented.

Mucoepidermoid carcinoma developed in tracheobronchjal tree is one of rare lung tumor. It is histologically divided into low grade malignancy of relatively benign course versus high grade malignancy of fatal course. In low grade malignancy, it can be curative with a surgical resection. We experienced a case of mucoepidermoid carcinoma in a 28-year-old woman who complained sudden dyspnea and presented right total lung collapse on chest roentgenogram. It was diagnesed as a low grade mucoepidermoid carcinoma and removed by the surgical excision.
