Capillary hemangioma of the lung. Radiological quiz

Capillary hemangiomas of the lung are very rare, usually presenting solitary circumscribed lesions on chest radiographs. Hemoptysis is frequently present. All 7 known patients with isolated pulmonary capillary hemangiomas have been females. The authors describe a girl followed up from 2 months to 3 1/2 years of age with a large lesion which at times appeared as a mass of water density and at other times as air-filled cysts. This changing radiological pattern correlated well with the pathological evidence of repeated hemorrhage, scarring, air trapping, and cyst formation.
