Radiologic Evaluation of Small Lepidic Adenocarcinomas to Guide Decision Making in Surgical Resection.

Background: The International Association for the Study of Lung Cancer/American Thoracic Society/European Respiratory Society classification of pulmonary adenocarcinomas identifies indolent lesions associated with low recurrence, superior survival, and the potential for sublobar resection. The distinction, however, is determined on the pathologic evaluation, limiting preoperative surgical planning. We sought to determine whether preoperative computed tomography (CT) characteristics could guide decisions about the extent of the pulmonary resection.

Radiology-Pathology Conference: 18F FDG PET-CT imaging of solitary fibrous tumor of the pleura.

Solitary fibrous tumors of the pleura (SFTPs) are mesenchymal neoplasms that arise from the pleura. SFTPs can grow slowly and may become big masses with malignant behaviors and metastases. The ratio of benign to malignant is 7:1, and pathology is necessary to differentiate between benign and malignant.
