Аннотация
BACKGROUND: Cavernous hemangiomas are usually located in the liver, skin, and subcutaneous tissues. Although they can arise from any organ, cavernous hemangiomas rarely occur as a pulmonary tumor. We herein report a rare case of a pulmonary cavernous hemangioma that was surgically resected.
CASE PRESENTATION: A woman in her 40s was found to have 2 well-defined nodules in the lower lobe of the left lung by computed tomography during following up of bladder cancer. She had a history of surgery for tetralogy of Fallot at 6 years old and pulmonary valve replacement for pulmonary valve insufficiency in her late 30s. She had also undergone surgery for bladder cancer. Although there was no accumulation of 18F-fluorodeoxyglucose on positron emission tomography (PET), the tumor slowly grows. Surgical resection was therefore performed to obtain a definitive diagnosis. The postoperative histological examination revealed an encapsulated nodule comprising large, dilated vessels lined with vascular endothelium and filled with blood, which led to the diagnosis of a pulmonary cavernous hemangioma.
CONCLUSION: We experienced a rare case of pulmonary cavernous hemangioma and reviewed the previous reports.
