Solitary pulmonary infantile hemangioma in an infant with atrial septal defect.
Pulmonary infantile hemangiomas are extremely rare in infancy and childhood. We describe a case of a 22-month-old infant who presented with repeated chest infections. Imaging studies revealed a solitary parenchymal lung lesion in the left upper lobe, an atrial septal defect, and mild right ventricular dilatation. Various investigations failed to delineate the precise nature of the lung lesion and it was resected. Histological examination of the lung lesion showed an infantile hemangioma, which expressed glucose transporter-1 protein, GLUT-1, a marker of infantile hemangiomas. This case represents a unique coexistence of 2 lesions, both of which resulted in right-sided overload, contributed to mainly by the atrial septal defect causing increased volume and, to a lesser extent, by the pulmonary hemangioma resulting in increased pressure. This case also emphasizes the fact that infantile hemangioma, although rare, should be considered as a differential diagnosis of solitary lung lesions.
