Large, well demarcated ovoid homogeneous opacity 9.5 x 5.5 cm in right upper zone. Given the sharp margins it is most likely pleural in origin (versus parenchymal). The distinct shape suggest that it follows the oblique fissure.
Case Discussion
Patient has a right pulmonary pseudotumor. This caused by a hematoma along the right oblique fissure. Minimal interval change. Differentials for such findings are a fissural cyst.
If clinically not infective, an infected hematoma is unlikely.
