Nasopharyngeal adenoid hypertrophy (NAH) is a typical benign lesion. DWI appearances of this lesion have not been reported previously.<\/jats:p>\n <\/jats:sec>\n \n Purpose<\/jats:title>\n To identify and to analyse DWI findings of NAH.<\/jats:p>\n <\/jats:sec>\n \n Material and Methods<\/jats:title>\n \n We analyzed 688 MR investigations of the head performed at our institution. Magnetic resonance imaging (MRI) was obtained at a 1.5\u2009T MRI device. Beside normal standard sequences DWI was obtained using a multislice single-shot echo-planar sequence. DWI was performed with b values of 0, 500, and 1000\u2009\u2009s\/mm\n 2<\/jats:sup>\n .\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n The mean whole lesion ADC value was 0.83\u2009\u00b1\u20090.12\u2009\u00d7\u200910\n \u20133<\/jats:sup>\n \u2009mm\n 2<\/jats:sup>\n s\n \u20131<\/jats:sup>\n (median, 0.82\u2009\u00d7\u200910\n \u20133<\/jats:sup>\n \u2009mm\n 2<\/jats:sup>\n \u2009s\n \u20131<\/jats:sup>\n ; range, 0.58\u20131.45\u2009\u00d7\u200910\n \u20133<\/jats:sup>\n \u2009mm\n 2<\/jats:sup>\n \u2009s\n \u20131<\/jats:sup>\n ). The mean ADC value of solid areas of NAH was 0.59\u2009\u00b1\u20090.11\u2009\u00d7\u200910\n \u20133<\/jats:sup>\n \u2009mm\n 2<\/jats:sup>\n \u2009s\n \u20131<\/jats:sup>\n (range, 0.36\u20130.84\u2009\u00d7\u200910\n \u20133<\/jats:sup>\n \u2009mm\n 2<\/jats:sup>\n \u2009s\n \u20131<\/jats:sup>\n ).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n Although NAH is a benign lesion, it shows low ADC values both in childhood and in adults.
