CT scans were performed in a supine and prone position with drug-induced hypotonia and water-filling of stomach with 500–700 ml., and intravenous administration of a non-ionic contrast agent. the prone position and drug-induced hypotonia allowed visualization of the whole gastric wall and prevented gas artifacts, commonly present during supine imaging. CT scans were analysed with respect to the...

conclusion ct scan is highly accurate in differentiating malignant pleural mesothelioma and metastatic pleural diseases. pleural thickening and thickening of interlobar fissure lead us to the diagnosis of mpm and massive free pleural effusion is more commonly seen in metastatic pleural malignancy. background malignant pleural mesothelioma (mpm) is a rare malignant neoplasm of the pleura that ty...

A 40-year-old man presented with left-side nasal obstruction for the past nine months. He had been treated for allergic rhinitis with nasal steroids for a long time. An anterior rhinoscopic examination was normal. Endoscopic examination revealed a nodulary mass in the nasopharynx, partially obstructing the left choana (Figure 1A). An endoscopic examination of the right nasopharynx revealed regu...

Case Report. A 27-year-old young woman presented wit...

Light chain deposition disease (LCDD) infrequently affects the lungs and usually causes damage to the parenchyma, while bronchial involvement appears to be very rare. The present authors report the case of a 64-yr-old female with LCDD characterised by asymptomatic airway involvement.
