RESUMO
The main aim of this work is to evaluate the role of MRI in patients suspected to have Morton Neuroma [Intermetatarsal Neuroma] and to assess the importance of the various MRI sequences in this disease. 30 Patients with a clinical suspicion of Morton Neuroma were examined with a 1.0 Tesla MRI scanner. T1W axial, T2W axial, fat suppression and T1W post contrast images were obtained. 16 patients out of 30 underwent surgery. Twelve patients out of 16, Morton Neuroma was proven surgically. 11 true positive, 1 false negative, 4 true negative and no false-positive MRI diagnosis were given. 5 of 12 proven Morton Neuroma, the clinician was unable to localize the exact intermetatarsal space. The MR results of the 14 remaining patients who did not undergo surgery were Morton Neuroma [n=4], stress fracture [n=1], non-specific fibrosis [n=2], and no abnormality [n=7].MRI is accurate in diagnosis and localization of Morton Neuroma. TIW images is the most important sequence, T2W images is included to define cystic lesions and bursa. STIR images are of some value while post Gad TIW images was excluded from the routine sequences and reserved for when other pathology is suspected
