Abstract

Background and objective: Perianal fistulae commonly occur in middle-aged men. It is important to determine the presence of fistula tracks, its grading and presence of abscess or inflammation. This study aimed to assess the role of MRI in diagnosis and classification of perianal fistula.Methods: This study included 20 patients with perianal sepsis that were referred to the MRI section of Radiology Department in Rizgary Teaching Hospital between August 2015 and April 2016. All patients underwent MRI examination.Results: The mean ± SD age of the 20 patients was 38.5 ± 10.4 years (range 22-55 years), of which 16 patients (80%) were males and four patients (20%) were females. Eighteen patients had a single external opening and two patients had two external opening. All the simple non-branching fistulas were successfully identified by axial and coronal planes of contrast enhanced T1Weighted image fast spin echo, of which five cases had simple intersphincter (G1) fistula and two had simple transphincter (G3), seven cases had intersphincter fistula either secondary tract or horse shoe and abscess (G2), five cases had complex transsphincter (G4). Two cases of complex G4 type had inflammation and edema in ischiorectal and ischioanal fossa and the internal openings were clearer in STIR T2axia.Conclusion: MRI non-invasively offers important information about perianal fistula that can reduce surgical complications and postoperative recurrence of the disease. Every patient with suspicious perianal sepsis should undergo MRI examination to prevent complications and morbidity.

Abstract

Background and objective: An incidental lesion is an asymptomatic lesion found while examining a patient for an unrelated reason. Lumbar spine imaging may reveal either clinically insignificant spine incidental abnormalities and/or extra-spinal Incidental finding that, at times, may even explain the patient’s symptoms. This study aimed to evaluate the frequency and types of incidental findings in lumbosacral magnetic resonance examination and to find the correlation between the frequency distribution of findings in terms of age and sex.Methods: This cross-sectional study involved 1250 persons who were referred for lumbosacral spine magnetic resonance imaging because of low back pain and/or radiculopathy. The magnetic resonance images were viewed to evaluate the frequency of incidental findings which were divided into extra and intraspinal findings.Results: Incidental findings were noted in 332 (26.6%) patients of the 1250 comprising 94 (28.3%) males and 238(71.7%) females. Some of them had more than one incidental finding. Cortical and para pelvic renal cysts were the most common extra spinal incidental findings, while vertebral hemangioma was the most common intraspinal incidental finding.Conclusion: Incidental findings were common in magnetic resonance imaging examination of the lumbar spine, and most were clinically insignificant; however some of these findings may be more significant than the spinal problems being evaluated and can have a significant impact on patient management. Therefore, they should be included in the reports since they will give additional and valuable information.
