Pulmonary vasculitis due to infection with Mycobacterium goodii: A case report

A 57-year-old Caucasian woman suffered from dyspnea on exertion. One year following a supposed pulmonary embolism event, a chronic thromboembolic vasculopathy was diagnosed and a pulmonary thromboendarterectomy was performed. However, a granulomatous pulmonary arterial vasculitis was identified upon examination. DNA of Mycobacterium goodii was detected as the most likely causative agent. Anti-inflammatory and anti-mycobacterial therapy was initiated for more than 12 months. Regular PET-CT scans revealed improvement under therapy. The last PET-CT did not show any tracer uptake following 10 months of therapy.
