The incidence and prevalence of NEHI are unknown, but it is clearly rare. Available data derive from small to moderate sized case series. The original report of this disorder in 2005 included 15 cases. A study from a large referral center identified 19 cases (14 percent) from among 138 lung biopsy cases accrued over a 10-year period. Twenty-three NEH cases were included in a separate study testing chest CAT scan. The largest report to date includes 37 cases in a manuscript focusing on infant pulmonary function testing (PFT)
