DIAGNOSIS:
Bronchoalveolar Carcinoma
A focal area of ground-glass attenuation and consolidation is seen in the superior segment of the right lower lobe showing a peri-bronchiolar pattern with sparing of the peripheral lung/cortex.
This is a pattern typically seen with cryptogenic organizing pneumonia (COP), earlier called BOOP. However, the lesion is unilateral and the patient had no fever, dyspnea or raised ESR, making this diagnosis unlikely.
The other condition that presents in this manner is bronchoalveolar carcinoma (BAC). A CT-guided biopsy confirmed this diagnosis.
