Case presentation

A 54-year-old man presented with progressive dyspnoea and non-productive cough for 2 months. A physical examination revealed diminished breath sounds and dullness to percussion on the right side. A preoperative chest radiograph for elective left knee arthroplasty 2 months prior to this presentation showed a 16 mm nodule in the right middle lung field (figure 1A).

(A) Chest radiograph showing a 16 mm right-sided lung nodule in the mid-lung field (red arrow). (B) Chest CTPA revealing a 4.5 cm solid, homogeneous, pleural-based mass with clear borders forming an obtuse angle with the chest wall. (C) Chest radiograph 2 months after the initial CT chest showing significant progression of the mass. (D) PET-CT chest demonstrating hypermetabolic uptake of the fluorodeoxyglucose of the large right pleural base mass. CTPA, CT pulmonary angiogram; PET-CT, positron emission tomography-CT.

A CT pulmonary angiogram obtained 1 month after left knee arthroplasty for the complaint of dyspnoea did not reveal pulmonary embolism, however, a well-circumscribed, homogeneous 5.2 cm pleural-based mass was found in right lower haemithorax (figure 1B). A …
