“…Interestingly, BCG has been described in association with pulmonary cavitation, asthma and aspergillosis [6][7][8][9][10][11][12][13][14][15][16][17][18], pulmonary echinococcosis [19], Wegener's granulomatosis [20], rheumatoid arthritis [10], ankylosing spondylitis [12], glomerulonephritis [13], scleritis [21], and polyarthritis [14]. Whilst involvement of the central nervous system has often been observed in Wegener's granulomatosis [4,5], it has never been described in BCG.…”
