Authors reviewed 21 cases of histologically confirmed rib tumor except metastasis and myeloma from Nov. 1973 to Dec. 1982 at Seoul National University Hospital. The resuls are as follows: 1. Major clinical findings are painand mass. 2. Pathologic diagnosis of rib tumors are 5 cases of fibrous dysplasia, 3 chondroma, 2 osteochondroma, 2desmoplastic fibroma, 3 chondroma, 2 osteochondroma, 2 desmoplastic fibroma, 5 osteosarcoma, 1 aneurysmal bonecyst, 1 eosinophilic granuloma, 1 cavernous hemangioma, 1 chondrosarcoma. 3. Radiologic findings are osteolyticchange and cortical expansion without marginal sclerosis in fibrous dysplasia, central location, well-definedosteolytic change with marginal sclerosis and no cortical destruction in desmoplastic fibroma, corticaldestruction, soft tissue mass and pleural effusion in malignant tumors.

Fat containing masses, except mediastinal lipomatosis, of the thorax are uncommon. In spite of uncommonoccurences, as CT can detect not only the fat content but also the presence and character of the non-fattycomponent of the mass, accurate preoperative diagnosis can usually be made in most cases of fat containingmediastinal masses. Authors report 6 cases of fat containing mediastinal masses, that were diagnosedpreoperatively by CT scan, comprising 2 cases of limpoma(combined with plexiform neurofibroma in a case), 1liposarcoma, 1 thymolipoma, and 2 cases of omental hernia through Morgagni foramen.

Both idiopathic pulmonary fibrosis (IPF) and pulmonary involvement of collagen vascular disease(CVD) are well known cause of diffuse interstitial lung disease which lead to fibrosis and honeycombing. We analyzed HRCT findings of 33 patients with IPF and 14 patients with CVD in terms of predominant pattern, site of involvement, mediastinal lymph node enlargement, pleural change and pulmonary volume loss. Criteria of mediastinal lymph node enlargement and pleural thickening were 15mm in long diameter and 3mm, respectively. Volume loss of the lung was measured by using hilar height ratio (apex to hilum/hilum to diaphragmatic dome). Mean age was 61 years for IPF and 46 years for CVD and male: female ratio was 27:6, 4:10, respectively. Predominant HRCT pattern was honeycombing for IPF (63%), and ground-glass opacity for CVD (66%) (p=0.001). Predominantly, subpleural involvement was seen in 90% for IPF and 74% for CVD. Mediastinal lymph node enlargement was seen in 47% of the patient with IPF and 14% with CVD (p=0.004). pleural thickening was seen in 97% of the patients with IPF and 42% with CVD (P=0.002), Pleural effusion was seen in 10% of the patients with IPF and 36% with CVD (P=0.009). Hilar height ratio of more than 1.5 was seen in 84% of the patients with IPF and 29% with CVD. In conclusion, our study shows that patients with IPF are prone to have more progressed stage of pulmonary fibrosis than the patients with CVD on HRCT.

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.
