OBJECTIVES: The aim of this study was to determine the prevalence of anatomical variations of the coeliac trunk and renal arteries and whether there is a relationship between the occurrence of these variations at Dr George Mukhari Academic Hospital METHOD: Arterial phase abdominal computed tomography (CT) or CT abdominal angiograms performed during January and December 2017 were analysed. The variations of the coeliac trunk and renal arteries were classified according to accepted classification systems and expressed as a percentage of the study population. RESULTS: A normal classical coeliac trunk was present in 82.2% and a non-classical pattern was present in 9.7%. The most common variation of the coeliac trunk other than the non-classical pattern was a hepatosplenic trunk, which was present in 3% of the study population. A normal right and left renal artery was present in 88.2% and 83.7%, respectively. The most common variations of the renal arteries were bilateral hilar arteries seen in 3.4% on the right and 9.1% on the left. Renal artery variations were more prevalent on the left than on the right. Concurrent variations of both the right and the left renal arteries were present in 2.4% and variations of both the coeliac trunk and renal arteries were present in 5% of the study population. CONCLUSION: The most common variation of the coeliac trunk in this study is comparable to other studies in non-African populations. Concurrent vascular variations between the renal arteries and between the coeliac trunk and renal arteries may co-exist. <![CDATA[<b>Imaging of retroperitoneal haemorrhage revealing median arcuate ligament syndrome</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S2078-67782021000100002&lng=pt&nrm=iso&tlng=pt Coeliac artery compression stenosis caused by the median arcuate ligament can lead to aneurysm formation in the pancreatico-duodenal arteries that can eventually result in a spontaneous rupture leading to retroperitoneal haemorrhage. In this case series, we describe the cases of three patients, all presenting with sudden epigastric pain, diagnosed as spontaneous haematoma, complicating a median arcuate ligament syndrome. <![CDATA[<b>A kaleidoscopic view of male urethral pathologies on 64-slice multidetector computed tomographic urethrography: A novel technique</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S2078-67782021000100003&lng=pt&nrm=iso&tlng=pt Pathologies of the male urethra are mostly obstructive in nature and require imaging to delineate the lesion type, site, extent and associated abnormality of the urinary bladder. Contrast urethrography (CU) is the gold standard investigation for urethral assessment but has many limitations. Cross-sectional imaging is infrequently used for the evaluation of the urethra but has been gaining importance recently. Multidetector computed tomographic urethrography (MDCTU) has the capability of evaluating the entire length of a male urethra in a single setting and overcomes many technical and patient limitations of CU. Being a novel technique, most radiologists are not familiar with MDCTU and the imaging spectrum of various urethral and bladder pathologies. This pictorial review attempts to present the imaging appearance of the normal male urethra and spectrum of pathological findings, with highlights on its advantages over the CU technique.
