    Background:Certain abdominopelvic vascular structures may be compressed by adjacent anatomic structures or may cause compression of adjacent hollow viscera. The knowledge of these CT patterns of compression is also important because they may be asymptomatic; when symptomatic, however, they can lead to a variety of uncommonsyndromes in the abdomen and pelvis, including median arcuate ligament syndrome, May-Thurner syndrome, nutcracker syndrome, superior mesenteric artery syndrome, uretero-pelvic junction obstruction, ovarian vein syndrome, and other forms of ureteral compression. Computed tomography is particularly useful in that it allows a comprehensive single-studyevaluation of the anatomy and resultant morphologic changes. Objective: To describe Abdominopelvic vascular compressions incidentally found on computed tomography. Method: Hospital based prospective cross sectional study was conducted at TikurAnbessa Specialized Hospital who undergo computed tomography scan of the abdomen between January and April 2019. The study population was all patients who undergo computed tomography scan of the abdomen .Data was collected by evaluating abdominal Computed Tomographic scans from Picture archiving and communication system. The data was checked for clarity and completeness. Computerized data analysis was conducted by using SPSS version 25.0 software. Result:Out of 623 multi detector abdominopelvic CT (MDCT)performed between January 2019 and April 2019;a total of 513 (N = 513) patients were included in the study out of which 35(6.8%) had fulfilled imaging features of SMA compression and 33(6.4%) of the patient fulfilled imaging features of nutcracker phenomenon and 22(4.28%) of the patients showed celiac compression by MAL. This study group comprised 277 (54 %) females and 236 male (46%) patients. Mean age of the patients was 38±20 (mean ± standard deviation). Conclusion:Incidental SMA Compression of duodenum, MAL compression of celiac artery and left renal vein compression by SMA are not uncommon and syndromic diagnosis should not be made on radiologic diagnosis alone. The SMA compression and nutcracker sign are usually seen together. High origin of celiac artery and low insertion of MAL are the main risk factors for compression of celiac artery which were seen in previous studies as well
