RT Journal Article SR Electronic T1 Primary lingual abscess presenting as acute swelling of the tongue obstructing the upper airway: diagnosis with MR. JF American Journal of Neuroradiology JO Am. J. Neuroradiol. FD American Society of Neuroradiology SP 496 OP 498 VO 19 IS 3 A1 A Muñoz A1 A I Ballesteros A1 J A Brandariz Castelo YR 1998 UL http://www.ajnr.org/content/19/3/496.abstract AB We report the sudden development of an inflammatory process thought to be of the floor of the mouth with subsequent involvement of the respiratory airway. MR imaging showed an enhancing posterior lingual lesion, consistent with an abscess. Immediate surgical drainage relieved the symptoms. MR imaging allowed accurate diagnosis, which was essential for surgical planning in a condition that was otherwise difficult to diagnose.
