Pulmonary Arteriovenous Malformations Requiring Surgical Resection Due to the Migration of Two Coils into a Single Lesion with <i>Mycobacterium avium</i> Complex Infection after Coil Embolization
A 21-year-old male with hereditary hemorrhagic telangiectasia underwent coil embolization for three pulmonary arteriovenous malformations (right S<sup>6</sup>c, right S<sup>10</sup>a, and left S<sup>6</sup>b). Three years after coil embolization, coil migration was observed in the right S<sup>6</sup>c and S<sup>10</sup>a, 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.
