The patients with MAC were older (mean 69 vs 58 years; P = .007). Patients with M xenopi more often had emphysema (50% vs 20%; P = .02), cavities (46% vs 16%; P = .01), and nodules \u22645 mm (88% vs 58%; P = .02). M xenopi cases more commonly had a fibrocavitary radiologic pattern (33% vs 18%), with no statistically significant difference ( P = .24). MA C was more often associated with a nodular bronchiectatic pattern (68% MAC vs 4% M xenopi; P &lt; .0001). Sixty-three percent of patients with M xenopi had a pattern that was predominantly randomly distributed nodules (11\/15 [73%]) or consolidation and\/or ground-glass opacities (4\/15 [27%]).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Compared with MAC, patients with M xenopi infection develop more cavities and more nodules, and they less often have a predominant nodular bronchiectatic pattern. Although a predominantly cavitary pattern appears to be more common with M xenopi, the majority of patients with M xenopi had CT patterns of random nodules or consolidation and\/or ground-glass
