Use of 18FDG-PET for malignant tumors of the pleura raises certain technical difficulties because of the small size of the tumors and their diffuse distribution, but hybrid PET/CT machines offer a better localization of FDG uptake. FDG-PET can discriminate between malignant and benign pleural tumors FDG uptake in the pleura is the best diagnostic criteria of malignancy. The presence of FDG uptake in pleural effusion is less discriminate between benign and malignant disease. ⋯ SUV<4 associated with an epithelial tumor is a sign of good prognosis at three years. SUV > 4 associated with a non-epithelial tumor is a sign of poor prognosis. For mesotheliomas, FDG uptake can be used to assess the effect of chemotherapy and determine whether patients are good responders or not.

Acute airway obstruction caused by mucoid impaction can cause sometimes life-threatening respiratory distress. Bronchial plugging is usually observed in subjects with chronic diseases such as asthma, allergic bronchopulmonary aspergillosis, or cystic fibrosis. In children, it can be related to heart failure. ⋯ The patient experienced acute respiratory distress with asphyxia. The plugs were composed of fibrin and required several fibroscopic procedures for clearance. To our knowledge, this is the first case report of acute airway obstruction by plugging during a period of agranulocytosis.
