A 10-week-old male was found to have a cavernous hemangioma in the right lower pulmonary lobe. Hemangiomas of the lung are infrequent and in pediatric patients exceptionally rare. This may explain why, among the catalogs of intrapulmonary cystic lesions in children, cavernous hemangioma is a conspicuously absent entity and is rarely imagined in the clinical differential diagnosis. We present one such case, establish its distinction from arteriovenous malformations, and briefly review the available literature.
