Pulmonary Sequestration and Intrathoracic Kidney: CT Diagnosis of a Rare Congenital Malformation with Bochdalek Hernia
When a Trauma CT Reveals an Entirely Different Story A 22-year-old woman was evaluated after falling from a scooter. Because the clinical question was trauma, the initial purpose of contrast-enhanced CT was straightforward: identify fractures, hemorrhage, solid-organ injury, vascular injury, or other acute traumatic abnormalities. No significant traumatic injury was identified. Yet the CT examination revealed something much more unusual.

Instead, it was located within the thoracic cavity through a left posterolateral diaphragmatic defect , accompanied by part of the left adrenal gland, the gastric fundus, and the spleen. The final imaging constellation was: Intralobar pulmonary sequestration + intr...
