Imaging characteristics of pleural tumours

ABSTRACT: Malignant mesothelioma is doubtless the more known pleural tumour. However, according to the morphology code of the International Classification of Diseases for Oncology (ICD-O), there are several histological types of pleural neoplasms, divided into mesothelial, mesenchymal and lymphoproliferative tumours, that may be misdiagnosed. In this paper we summarise and illustrate the incidence aspects and the clinical, pathological and radiological features of these neoplasms. TEACHING POINTS: • According to the ICD-O, there are 11 different histological types of pleural neoplasm. • Imaging, clinical and histopathological aspects of these neoplasms may be overlapping. • Knowledge of different pleural tumours plays an important role for diagnosis orientation.
