Chest computed tomography (CT) showed multiple pleural base nodules along the left posterior and posterolateral chest wall, measuring up to 34 mm (Fig. 1a-e), chronic left rib fractures, and a small area of splenic tissue beside a large cystic mass in the left upper quadrant (Fig. 2).
Microscopic examination of the pleural lobulation confirmed splenic tissue, including white pulp (arrow) embedded in a red matrix (red pulp). Scale: (a,c) = 4x magnification, (b) = 20x magnification.
