Abstract Objective To evaluate the usefulness of magnetic resonance imaging (MRI) in Tietze’s syndromesyndrome which,which, toto ourour knowledge,knowledge, hashas notnot previously been reported in the literature. Methods Twelve consecutive outpatients with clinical features of Tietze’s syndromesyndrome underwentunderwent evaluation,evaluation, includingincluding tthehe aanamnesis,namnesis, clinical general examination, clinical evaluation of costosternal and sternoclavicular joints (SCJ) and biochemical and instrumental investigations. Twenty normal subjects age- and sex-matched to the patients’ groupgroup werewere examined in a similar manner. MRI of costosternal and SCJ was performed using a 1.5 Tesla unit (Gyroscan NT 1.5 Philips, The Netherlands and GE Signa Excite HD, GE Healthcare, Milwaukee, Wis., USA). Results The MRI pattern of primary Tietze’s syndromesyndrome waswas characterizedcharacterized asas follows:follows: enlargementenlargement andand thickeningthickening ooff ccartilageartilage aatt the site of complaint (12/12 patients); focal or widespread increased signal intensities of affected cartilage on both TSE T2-weighted and STIR or FAT SAT images (10/12 patients); bone marrow oedema in the subcondral bone (5/12 patients); vivid gadolinium uptake in the areas of thickened cartilage, in the subcondral bone marrow and/or in capsule and ligaments (10/12, 4/12 and 7/12 patients respectively). Conclusion Magnetic resonance is an excellent technique to evidence both the cartilage and bone abnormalities, therefore it represents the elective method in the investigation of primary Tietze’s syndrome,syndrome, duedue toto itsits highhigh sensitivity,sensitivity, ddiagnosticiagnostic rreliabilityeliability aandnd biological advantages thanks to the lack of ionizing radiation.
