We present a case of a 54 years old male who initially presented with one month history of worsening epigastric pain and vomiting. He was referred to our care after an ultrasound and CT abdomen showing dilated common bile duct up to 13mm with no obvious intraductal obstruction. An incidental type 1 duplicated IVC was demonstrated on the CT abdomen (Figure and 2).\nNo intra-abdominal mass or lymphadenopathy were detected. Notably, he is a known BRCA2 mutation carrier. Both, his mother and sister had BRCA2-positive breast cancer. One of his great uncles also had male breast cancer. The patient was clinically jaundiced on presentation, with a bilirubin of 106. His other liver function tests were ALT at 465, GGT at 1032 and at ALP 271. His tumour markers CA-125 and CA-199 were 12 and 94 respectively.\nThe patient was subsequently found to be hypotensive and tachycardic with a new drop in haemoglobin from 100 to 72 during his stay. An urgent gastroscopy then revealed a 10mm punched-out ulcer with adherent clot at the ampulla. The lesion was partially obstructed and no active bleeding was seen. Histology on biopsy showed moderately differentiated adenocarcinoma. CT angiography was then performed. No active extravasation was seen and the gastroduodenal artery was empirically embolised with microcoils. An apparent cavitation at the medial aspect of the second part of duodenum was now identified on the CT imaging (Figure ). No metastasis was seen on staging CT imaging.\nA whipple procedure was performed. The duplicated right IVC was visualised intraoperatively with mobilisation of the uncinate process but appeared relatively normal. The left sided IVC was not encountered. No major complications were reported during his inpatient stay. Patient was discharged home and subsequently commenced on adjuvant therapy.
A 46-year-old lady underwent CT chest abdomen and pelvis for breast cancer staging. The CT was reported as free of secondary pathology; however, the below-discussed findings were observed.\nThe CT scan shows the infrarenal tract of the IVC localised on the left side of the aorta. This left paramedian IVC is of normal calibre and crosses the middle line at the level of the celiac trunk, behind the aorta (). At T 12, the IVC continues its way up to the chest as Azygos vein, passing through the aortic hiatus of the diaphragm. No embryologic remnants of the supracardinal veins are noted on the right side of the aorta. A large vein is located ventromedially to the ureter on both sides, consistent with large ovarian veins. Furthermore, the right renal vein follows an anomalous course, as it is situated posteriorly to the aorta to drain into the left-sided IVC. Finally, a partial duplication of the left ureter is noted ().
