There is a large cavitary lesion with gas-fluid level and mottled gas foci seen at the left lower lung lobe associated with pulmonary infiltrates around it. It shows post-contrast wall enhancement in keeping with lung abscess. This lung abscess shows subdiaphragmatic extension through a defect in the left diaphragmatic copula.
Sutures for sleeve gastrectomy are seen. Lateral to the stomach, there are multiple hyperdense clumps and few gas foci. These changes are suspicious for leaks from a perforated bowel. The hyperdense clumps are mostly representing leaked contrast from the stomach as the patient had a previous CT study with oral contrast at another institute.
Hepatic haemangioma (confirmed by triphasic CT), small gall bladder stones (confirmed by ultrasound) and accessory splenule are also noted.
