Since, occult metastatic disease was a possible reason for the symptoms, a PET scan was done, which Roeke T, et al.

These finding where suggestive of mycotic aneurysm [duration of treatment to reaction onset not stated]. Since, he did not experience any septic episodes, and pointers of infection stayed only mildly raised, it was decided to implement elective open aorta re-constructive surgery in the short period of time. The man underwent surgery in February 2016. The aneurysm started just caudal to the renal arteries. He was planned for a neoaortoiliac system bypass. However, due to limited infected area, reconstructive repair was done with a bovine (pericardial) tube graft. The infected aneurysmal segment was removed. A group of softened and infected mushy tissue was observed on the left side of the aneurysm. A culture and biopsy sample from the surrounding tissue and aorta were collected. All tissue presenting signs of infection were removed. A resorbable sponge soaked with gentamicin was left behind in the cavity post removal of the aneurysm and surrounding the infected tissue. Subsequently, rifampicin was directly applied to the cavity, and the graft was sutured and protected with a greater omentum wrap plasty. Three samples of para-aortic tissue were cultured. One sample showed Mycobacterium bovis. Pathologic evaluation revealed extensive granulomatous and necrotising inflammation of the aorta. However, the histologic Ziehl-Neelsen staining used to recognise acid-fast organisms such as Mycobacterium bovis was found to be negative. DNA examination revealed that the cultured strain of Mycobacterium bovis was identical to the one used for the BCG solution, which was administered in 2013. This BCG solution was the source of the Mycobacterium bovis infection causing mycotic aortic aneurysm. Initially, the exact resistance-related features of the mycobacterium were not known. Hence, initially he was treated with ethambutol, pyrazinamide, isoniazid, and rifampicin. The moment it became clear that Mycobacterium bovis had produced the infection, treatment with pyrazinamide was discontinued. Postoperatively, he experienced severe inflammatory response syndrome (of an unknown aetiology) and was hospitalised to the ICU. Additionally, he developed acute on chronic renal insufficiency (of an unknown aetiology), for which haemodialysis was performed. His postoperative course was complicated by accumulation of chylous ascites and paralytic ileus (of an unknown aetiology). He was treated with a combination of total parenteral nutrition, paracentesis and octreotide for chylous ascites. Gradually, his condition improved and haemodialysis was discontinued. Chylous ascites production substantially diminished, and the ileus resolved. He was moved to the general surgery ward. Subsequently, his condition improved and he was moved to a rehabilitation center 2 months post surgery. He continued receiving ethambutol, isoniazid and rifampicin. Three months post discharge, he was re-admitted with malaise, generalised 0114-9954/18/1704-0001/$14.95 Adis © 2018 Springer International Publishing AG.
