RESUMEN
An 82-year-old woman with past history of pulmonary nontuberculous mycobacterial infection complained of hemoptysis and was pointed out the strongly stained nodule in the middle lobe of the right lung on chest enhanced computed tomography (CT), which was suggested to be peripheral pulmonary artery aneurysm. Angiography of the right internal thoracic artery (RITA) revealed the peripheral pulmonary artery aneurysm with the shunt from the branch of the RITA, which was considered to be the cause of hemoptysis. Transcatheter arterial embolization was performed for the branch of the RITA 2 times, however, the hemoptysis recurred again after 5 months. Therefore, after the third embolization for the RITA, the right middle lobectomy with amputation of the shunt vessel was performed. The patient has been well without hemoptysis for one year and 6 months after the surgery.

Coil embolization is widely performed for pulmonary arteriovenous malformations (PAVMs). We describe herein 2 cases of hemoptysis during long-term follow-up after coil embolization for PAVMs. For both cases, lobectomy was performed and histopathological examinations revealed chronic inflammation and bronchial epithelium extension into the sac of the PAVM. In addition, we performed a systematic review of previous reports of hemoptysis after embolization for PAVMs.
RESUMEN
CASE PRESENTATION: A 70-year-old woman who had received a diagnosis of pneumonia in the right lower lobe was treated with antibiotics at a general practitioner's clinic 9 months earlier. Her pneumonia had improved, but the cough and lung infiltrates persisted for > 6 months, so the patient was referred to our hospital. She had undergone surgery for breast cancer 30 years earlier but had no other medical history. She was not taking any medications and had no history of smoking, including passive smoking.
