Abstract:
Background & Aims: Low back pain is one of the most common problems and a symptom-related reason for visits to a physician, and one of the important causes of disability. It may also impose great costs on the individual and the health system. Most patients with back pain will recover within ۴ to ۶ weeks. One of the best paraclinical diagnostic methods is magnetic resonance imaging (MRI), which may result in incidental findings of great importance to the patient. Methods: In this cross-sectional study, all cases in which lumbosacral MRI was performed due to back pain were investigated in terms of incidental findings. Results: The MR images of ۸۵۴ patients in ۲۰۱۲ were studied. Among these patients, ۴۰.۳% (۳۴۴) were male and ۵۹.۷% (۵۱۰) were female. Mean age of patients was ۴۳.۰۵ years with median of ۴۲ years. The incidental findings were observed in ۲۹.۷% (۲۵۴) of cases who had no clinical symptoms and were not investigated by the physician. Abnormal incidental findings were observed in ۹.۵% (۸۱) of male and ۲۰.۲% (۱۷۳) of female patients; this difference was significant (P = ۰.۰۰۱). The prevalence of incidental findings was significantly higher in men of above ۴۲ years of age (P = ۰.۰۰۱), but this difference was not significant in female patients (P = ۰.۵۱۳). In total, the prevalence of incidental findings was higher in ages above ۴۲ (P = ۰.۰۰۴). The most prevalent incidental findings were, respectively, renal cysts (۱۱.۵%), retroflection of uterus (۵.۷%), and ovarian cyst (۴.۳%). Life threatening findings were aortic disorders (n=۱۱, ۱۱.۳ %) and important lesions (n=۲۸, ۳.۳%) requiring investigation. Conclusion: Incidental findings in MRI are important and since they might be the origin of pain or health threatening, require further evaluation.
