ABSTRACT
Endobronchial lipoma is a rare benign bronchial tumour. A search should be carried out on submillimetre MDCT scan slices in patients presenting segmental or lobar collapse or recurrent pulmonary infection in the same bronchial territories. The authors report MDCT and MR imaging in a patient with endobronchial lipoma discovered on an MDCT scan.

PURPOSE: Evaluate the feasibility of the virtual pleuroscopy (VP) in the detection of the pleural plaques. METHOD AND MATERIALS: Twenty consecutive patients, having asbestos exposure, explored by unenhanced multidetector CT-scan (Siemens, Sensation 16). The imaging parameters were as follows: beam width, 12 mm; beam pitch, 1; and reconstruction thickness, 1mm every 0.8mm at 120 kV and 180 mA. The image display used a surface-rendering algorithm and produced perspective red-scale images with a matrix of 512 x 512. Each VP image simulated a coned-down view, with a variable cone angle to explore the diaphragmatic pleura. The camera was placed 1 to 2 cm above the diaphragmatic dome. Four views are studied by diaphragm: crâniocaudal, lateral tangential, anterior and posterior. The observed virtual pleura aspect was classified in 5 groups (gr): gr 1: Rib band, gr 2: lobulated pleural thickening, gr 3: spicular, gr 4: plaques and gr 5: nodules. The results were compared to the other MDCT images using multiplanar reformatting. RESULTS: The visualization of each diaphragm was optimal (35/40; 87.5%), limited (3/40; round atelectasis and asbestosis) or impossible (2/40; asbestosis). The classifications of the studied 38 diaphragmatic pleura were: gr 1 (n=15), gr 2 (n=5), gr 3 (n=11), gr 4 (n=7), gr 5 (n=0). The MDCT analysis showed normal pleura for both gr 1 and gr 2, a confirmed or beginning of fibrosis for gr 3 and confirmed the presence of pleural plaques on the diaphragmatic pleura in all cases of gr 4. CONCLUSION: The virtual pleuroscopy is a reality. It is a feasible technique. Other studies are necessary to confirm these preliminary results.

AIM: To show and compare to literature CT findings in round atelectasis. MATERIAL AND METHODS: It is a retrospective review of the clinical and radiological files of 21 patients (17 men; 4 women; Mean age: 62), having asbestos exposure (6/21) or pleural history (13/21) and in whom the diagnosis of round atelectasis was performed from 1988 to 1998. This diagnosis was based on the presence of the classical radiological triad: round mass abutting to pleurae, converging bronchovascular markings and pleural thickening adjacent to the mass associated at a one year follow up or three years radiological and clinical follow up or the association with three minors radiological signs. RESULTS: The 25 round atelectasis, 4 bilateral, were localized in the lower lobes (22/25) or upper lobes (3/25) at right (17/25) or left (8/25) side. Minor signs were found as in literature as followed: air bronchograms and centrally indistinct margin (25/25, diffused pleural thickening or pleural plaques (19/25), acute angles with the pleura (18/25), fissures displacement (18/25), main stem bronchus displacement (13/25), calcifications within the plaque (10/25), calcifications within the mass (10/25). A mean of 6.7 signs was found for each lesion. CONCLUSION: More than the major signs of round atelectasis the air bronchogram, the centrally indistinct margin and the presence of one sign of retraction were very frequent. The mean number of signs was 6.7 for every lesion.

The objective of this study was to determine the utility of CT scan findings for the diagnosis of chest wall tuberculosis, excluding the spine. We reviewed 15 patients (13 Africans and 2 Indians) with chest wall tuberculosis, retrospectively. The radiologic examination consisted of a plain X-ray and a CT scan of the chest for each patient. The site of disease was the rib in 13 patients or the body of the sternum in 2 patients. One rib was involved in 11 patients, 2 contiguous ribs (one site) in 2 patients, and bilateral disease (two sites) was observed in the remaining patient. The 14 rib sites involved the posterior arc or costovertebral joint in 11 cases, the anterior arc in 2 cases, and the anterior and middle arc in 1 case. The CT scan findings were an abscess (n = 14) or a soft tissue mass (n = 2), osteolytic lesions (n = 13), periosteal reaction (n = 10), and sequestrum (n = 14). Bone sclerosis was observed only in 3 cases of rib involvement. The association of a soft tissue abscess, an osteolytic lesion, and sequestrum, especially in immigrants to France, suggests chest wall tuberculosis on CT scan.

Headache in the temporal, frontal and suboccipital regions are described as to case history, findings and differential diagnosis. With due respect to possible further symptoms of dysfunction, the author indicates as principles to treatment: 1. restoration of the continuity of the rows of teeth, and of the occlusal relations; 2. restoration of correct jaw relations; 3. rehabilitation of masticatory muscles.

The inclinations of the articular tubercles were measured on Schüller radiographs of the temporomandibular joints. They were significantly flatter in patients than in control subjects. Patients having pain showed considerably more frequently right-left different angles of inclination than patients being free from pain. The widths of the interarticular spaces were subdivided into 3 classes as suggested by Kleinrok. Again it was found that right-left dissimilarity (class III) was significantly more frequent than right-left similarity (class II) only in patients having pain.
