A resected case of solitary capillary hemangioma of the lung suspected to be lung cancer

A Case of Solitary Pulmonary Capillary Hemangioma

“…6 Recurrence or metastasis of this entity has not been reported. 3,7 CT values of the present case showed equivalent to water with poor contrast effect in the central part of the lesion and gradually increasing contrast effect in the margins. Pathologically, the central component of the lesion contained edematous alveolar interstitium, erythrocytes, and slight air space, the sum of which was considered to be the CT values equivalent to water on unenhanced CT.…”

The pathogenesis of SPCH is unknown, and it presents as a solitary nodule in the peripheral lung and is asymptomatic with a good prognosis 3 . It has been reported as a solitary nodule measuring 0.3 to 2.0 cm, most commonly in the lower lobes of the lung 4,5 .…”
