From: Tumor and tumorlike conditions of the pleura and juxtapleural region: review of imaging findings
Diagnosis: chondrosarcoma. Technique: standard chest radiography and contrast-enhanced chest CT. Description: A 25-year-old male presented with progressive worsening, inspiration-bound thoracic pain. Postero-anterior and lateral chest radiographs (a, b), which were performed to rule out a spontaneous pneumothorax, show a unilateral right-sided pleural effusion. Further diagnostic work-up with CT was performed. Axial contrast-enhanced CT (c) shows a massive pleural effusion masking a heterogeneous tumoral mass arising from the posterior side of the 10th rib with arc-and-ring calcifications. The locoregional bone destruction is best seen in the bone window (d). The postero-anterior and lateral chest radiographs after drainage of the pleural fluid (e, f) reveal the nodular mass (arrow) projecting into the right paravertebral on the PA image and posterior in the right lower lobe on the lateral chest radiograph. These imaging characteristics were suggestive of a chondrosarcoma, which was histopathologically confirmed after surgical resection
