Intrathoracic hybrid lesion: an incidental finding in a patient with PHACE syndrome

Hybrid lesions (HLs) are unique, congenital lung malformations with both cystic and solid components and vascular supply consistent with bronchopulmonary sequestration. Increase of HLs reported in recent literature suggest a common pathological mechanism occurring during embryogenesis, leading to occurrence of both malformations within a single lesion. Due to the unusual nature of HLs, gold standard approach for diagnosis is not very well-defined in the literature. We report a novel case of a 3-year-old girl with posterior fossa anomalies-haemangioma-arterial lesions-coarctation of the aorta-eye anomalies syndrome, who was found, on CT angiography, to have a previously missed HL diagnosis which was confirmed after surgical resection.
