Mycobacterium abscessus, an Uncommon Cause of Chronic Otitis Media

Otomastoiditis caused by non-tuberculous mycobacteria: report of 16 cases, 3 with infection intracranially

“…None of the three patients with intracranial spread had any neurological symptoms. In previous reports, 8 per cent of cases (4 out of 52) had evidence of intracranial spread 1 – 4 , 6 – 9 , 12 , 14 – 27 , 29 – 32 . The lymphatic glands were enlarged in two cases in this study.…”

“…Since 1976, 72 sporadic cases have been reported in 31 publications 1 – 12 , 14 – 32 . In addition, 17 patients were infected from the same source of ear rinsing water in an ENT practice in 1987, 13 making a total of 89 previously published cases.…”

“…Previous reports indicate that children with M avium complex infections are younger than children infected with other species of non-tuberculous mycobacteria (median of 2 years vs 5.5 years) 4 , 6 , 9 , 17 , 22 , 25 – 27 , 31 . Only 44 per cent (4 out of 9) of the children infected with M avium complex reported previously had been treated with ventilation tubes, 6 , 9 , 17 , 22 , 25 – 27 , 31 compared to 96 per cent (55 out of 57) of the children infected with other strains of non-tuberculous mycobacteria (ventilation tubes or perforation) 2 , 5 – 7 , 12 , 13 , 28 – 30 . M avium complex infections in young children typically affect neck lymph nodes.…”

“…The presence or absence of bone destruction of the mastoid in previous reports was, however, difficult to judge because intra-operative findings and imaging findings were not always described in detail. Nevertheless, bone destruction was distinctly described in almost half of the cases (17 out of 40) 1 – 3 , 6 – 9 , 12 , 14 – 17 , 19 , 21 – 26 , 28 , 29 , 31 , 32 Table IVDisease spread and surgical treatment…”

“…In 81 per cent (42 out of 52), the infection was limited to the temporal bone as indicated by operative and/or imaging findings. In 6 per cent (3 out of 52), the disease was limited to the middle ear 1 – 4 , 6 – 9 , 12 , 14 – 27 , 29 – 32 …”
