Malignant pleural mesothelioma with heterologous osteoblastic elements - Computed tomography, magnetic resonance, and positron emission tomography imaging characteristics of a rare tumor

The imaging findings of a rare mixed type of malignant mesothelioma of the pleura with heterologous bone stroma in a patient without a previous history of asbestos exposure are reported. Imaging findings of this type of bone-forming pleural mesothelioma are scarcely reported in the literature, with only a few case reports describing findings on conventional radiography, computed tomography, and magnetic resonance imaging. To the best of our knowledge, no positron emission tomography imaging characteristics of this type of mesothelioma have been previously reported.
