From: Mycobacterium tuberculosis aortic graft infection with recurrent hemoptysis: a case report
Radiographic, pathological and microbiological findings. (A) Computed tomography (CT) showing the presence of an air bubble anterior to the vascular graft, suggesting an aorto-pulmonary fistula. (B) Surgically excised Dacron prosthesis from which Mycobacterium tuberculosis DNA was amplified and M. tuberculosis grew in culture. (C) Inflammatory cells on a scraping of the prosthesis. No granuloma formation is seen (hematoxylin eosin staining). (D) Ziehl-Neelsen staining of the scraping of the prosthesis showing numerous acid-fast bacilli.
