Background:obstructive jaundice is a common clinical problem in medical practice.The condition can berncaused by theobstruction of the bile duct with choledocholithiasis, strictures and hepato-biliarymalignancy.rnObjective: To assess imaging spectrum, level and pattern of obstructive jaundice on cross sectional imaging, CTrnand MRCPrnMethods: A retrospective analysis of all patients admitted with a diagnosis of obstructive jaundice atTikurrnAnbessa hospital fromJan 2010 to Aug. 2012 E.CrnThe data were collected from patient medical records and PACS using pretested, structured data extractionrnformat was used to collect the data, which were entered onto andanalyzed using SPSSversion 2 5.rnResults: A total of 105 patients, 73 (69.5%)were males. Theirage ranged from 25 to 83 years with a mean agernof 53(Â±SD)13.8years. 79(75.2%) of the cases had malignant causes while the rest 26(24.8%) had benign causesrnfor obstructive jaundice. The most common malignant lesion was cholangiocarcinoma with 33 cases followedrnby pancreatic cancer which was seen in 28 cases. The most common benign lesion seen wasrncholedocholithiasis which was seen in 9 cases followed by benign Stricture which had 6 cases . The commonestrnsite of obstruction was at the peri- ampullary region in 40(38.1%) of the cases followed by distal common bilernduct and the hepatic hilum with 35(33.3%) and 20(19%) respectively. The most common imaging findings wasrnan enhancing intraluminal soft tissue mass which was present in 67(63.8%) which was followed by a focal wallrnthickening.Abdominal CT and MRCP wasthe main imaging modality used.rnConclusion:The most common imaging spectrumof obstructive jaundice are malignant lesions withrncholangiocarcinoma being the commonest and choledocholithiasis is the commonest benign causenoted withrnperiampullary region the commonest level/site of obstructi ve jaundice and intraluminal enhancing mass therncommonest pattern noted both in the cholangiocarcinoma and pancreatic head tumor.
