Objective: To assess the importance of incidental extraspinal findings on\nMagnetic Resonance Imaging of the lumbar spine in two hospital facilities.\nMaterials and Methods: It was a descriptive and retrospective study from\nNovember 2015 to March 2016. The records of patients who had done a\nMagnetic Resonance Imaging (MRI) scan of the lumbar spine were re-read in\nsearch of incidental findings. The incidental findings found were classified\nusing Colonography Reporting and Data System(C-RADS) classification of\nextracolonic lesions to assess clinical significance. The prevalence of incidental\nfindings was calculated for each facility, as well as the distribution according\nto age, the organs involved and the clinical importance. A non-detection rate\nwas calculated by confronting the findings of the study with the original reports.\nResults: The prevalence of incidental findings was respectively 33% (19\nout of 36) in Jordan Medical Center (JMC) in Yaounde and 27.74% (106 out\nof 292) in Jacques Monod Hospital. The extraspinal incidental findings were\nclassified mainly as extracolonic 2 (E2): 58% in each facility. The percentage\ndetection of incidental findings was 5% at JMS and 1.7% at Jacques Monod\nHospital. Conclusion: Extraspinal incidental findings are frequent in both\nhospitals. However, the rate of detection remains very low.
