Rare case of a proximal descending thoracic aorta mycotic aneurysm following intravesical BCG injections for the treatment of bladder cancer.
Article in BMJ case reports, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
A 79-year-old man presented with an enlarging thoracic aneurysm on the background of superficial bladder cancer treated with intravesical bacillus Calmette-Guérin (BCG) injections. Following the injections, he developed deranged liver function tests and hepatomegaly. Liver biopsy revealed granulomatous hepatitis compatible with disseminated mycobacterial infection (BCG-osis) and was treated with anti-tuberculosis agents for 12 months. A surveillance CT scan performed as a follow-up for his bladder cancer in 2018 revealed a saccular thoracic aneurysm at the ligamentum arteriosum, which was metabolically active on positron emission tomography (PET) scan. Given the timeframe from intravesical instillation of BCG and the metabolic activity on PET scan, the lesion was consistent with a mycotic aneurysm secondary to disseminated mycobacterial infection. Following multidisciplinary team discussion, a thoracic endovascular aneurysm repair was performed. The stent grafts were placed distal to the left subclavian artery with good angiographic results and no immediate postoperative complications. He was initiated on long-term antibiotics to cover potential bacterial pathogens including mycobacterium.
