Ann Pak Inst Med Sci Jan ;8(1):35-7.

Objective: To determine the diagnostic accuracy of magnetic resonance imaging (MRI) in morton neuroma using histopathology as a gold standard. Place & Duration of Study: This study was carried out in Pakistan Institute of Medical Sciences, Islamabad from November 2009 to October 2011. Study Design: Case Series Materials and Methods: It included 9 patients who presented with complaints of localized pain in the forefoot which was worsened by wearing shoes and by walking. MRI was done in all these patients and the findings noted. After the MRI, biopsy was done and the histopathological diagnosis was used as the gold standard. Results: The age of patients diagnosed with morton neuroma ranged from 32-46 years and the male to female ratio was 1:7. Out of the 9 patients, 8 patients were diagnosed according to MRI findings to have Morton neuroma and 1 patient was diagnosed as having bursitis. Later on, the patients were followed and biopsy was done and the MRI findings were correlated with the histopathological findings. There were 8 true positive cases and 1 true negative case. The sensitivity and specificity of MRI was 100% for the diagnosis of morton neuroma. The diagnostic accuracy of MRI in morton neuroma was determined to be 100%. Conclusion: MRI is a safe and accurate test in the diagnosis of morton’s neuroma.
