AI Article Synopsis
- * Three years post-procedure, coil migration occurred, leading to the formation of a cavity between the coils, which merged into one lesion by the fourth year.
- * The patient underwent right lower lobectomy due to severe hemoptysis, and the examination revealed a granuloma caused by Mycobacterium avium complex (MAC), but he had no further symptoms or recurrence after surgery.
Article Abstract
A 21-year-old male with hereditary hemorrhagic telangiectasia underwent coil embolization for three pulmonary arteriovenous malformations (right Sc, right Sa, and left Sb). Three years after coil embolization, coil migration was observed in the right Sc and Sa, and a cavitary lesion developed between the two coils. Four years after embolization, the two coil lesions were found to have merged within the cavity. Right lower lobectomy was performed for severe recurrent hemoptysis. A histological examination revealed a granuloma with caseous necrosis related to Mycobacterium avium complex (MAC) infection around the cavity. The patient did not exhibit hemoptysis or MAC recurrence after resection.
