Response: CT Angiogram Thoracic Aorta: Arterial phase contrast enhanced scans were performed (Omnipaque 350). No previous cross-sectional imaging for comparison.  Findings: No traumatic aortic injury or mediastinal haematoma. Note is made of a patent ductus arteriosus. The right heart and pulmonary arteries not dilated. Remnant thymic tissue noted. No enlarged hilar, mediastinal or axillary lymph nodes. The lungs are clear with no consolidation, collapse, pulmonary nodules or masses. No pneumothorax or pleural effusions. Multiple locules of gas and associated stranding/haematoma are in keeping with a soft tissue injury anterior to the midshaft of the left clavicle. No underlying fracture of the imaged clavicle.

Response: Despite timing for a portal venous phase study, the images are relatively arterial, reflecting a poor cardiac output.There is a large pneumoperitoneum and gas in the wall of the entire small bowel. The large bowel contains fluid but no gas in its wall. Gas is also present within the mesenteric veins and extends into the hepatic portal veins.Patchy enhancement of the liver and spleen may reflect infarcts.There are tight stenoses at the origins of the coeliac axis and superior mesenteric arteries. A short occlusion of the SMA is also present with very narrow calibre branches beyond the occluded segment.The inferior vena cava is flat and the adrenals are hyper-enhancing, consistent with shock.

Response: Single intrauterine fetus with a cephalic presentation. The uterus has an irregular contour at the right mid and inferior lateral edge and there is adjacent hyperattenuating fluid. Right anterolateral placenta has active contrast blush on angiogram with pooling of blood on PV phase imaging, in keeping with active placental bleeding. A 3cm focus of acute haemorrhage is adjacent to the inferior left uterus. Hyperattenuating fluid representing with haemorrhage is also demonstrated adjacent to the inferior liver and splenic edges. Liver and spleen otherwise appear normal with no parenchymal injury evident. Duplex left kidney. Both kidneys otherwise normal. Gallbladder, adrenal glands and pancreas have a normal appearance. Small bowel loops are adjacent to the inferior right aspect of the uterus where this is haemorrhage, however no discrete bowel injury is demonstrated. No free gas. Aorta, IVC and portal vein have a normal appearance. No pelvic or hip fractures. Normal lumbosacral spine. Impression  Active placenta haemorrhage and irregular uterine wall as described with free intraperitoneal blood is concerning for uterine wall injury. Small amount haemorrhage at the inferior liver and splenic edges without discrete injury demonstrated, most likely tracking up from uterine injury. Small bowel loops are adjacent to the haemorrhage at the right inferior uterus, however no discrete bowel injury is demonstrated.

Response: Concentric bowel wall soft tissue thickening over a 5.8 cm segment of the mid transverse colon is evident and is highly suspicious for colorectal carcinoma. Resultant short colo-colonic intussusception.Several small adjacent nodules measuring up to 6 mm in diameter may reflect local metastases. No enlarged mesenteric lymph nodes identified.A degree of faecal loading proximal to the lesion is noted with no evidence of gross bowel obstruction. No distended loops of bowel. Extensive sigmoid diverticular disease is demonstrated with no evidence of acute diverticulitis. No free fluid or free gas identified.A 5 mm well defined low attenuation lesion within the left lobe of the liver is too small to accurately characterise but is likely to represent a small hepatic cyst. A tiny calcification within the right lobe of the liver is compatible with a small calcified granuloma.Small nodules in the left anterior suprarenal location are of uncertain aetiology and may reflect prominent lymph nodes. Multiple small cortical defects involving the kidney likely reflect previous small cortical infarcts. No hydronephrosis. The spleen, adrenals and pancreas are unremarkable.The partially imaged lung bases are essentially clear.Extensive degenerative disease of the lumbar spine is demonstrated including partial fusion of the L2 and L3 vertebral bodies. No suspicious osseous lesion identified.CONCLUSION: Concentric soft tissue thickening involving the mid transverse colon over 5.8 cm likely reflects colorectal carcinoma. Small adjacent noudules may reflect local metastases. No distant metastatic disease identified.

Response: Distal pancreatic atrophy and MPD dilation are visible, but the pancreatic head and neck and proximal MPD appear normal. An infiltrative soft tissue around the vessels is visible at the level of MPD transition. It encases the common hepatic artery, the splenic vessels, portal vein confluence, and adjacent portal trunk, and SMV. SMA abutment suspected. A large hypo-enhancing area in the central part of the liver in segment 4th, 8th, and central part of segment 5th raises the possibility of metastasis. A single large metastasis from pancreatic adenocarcinomas is unusual. Two hypodense lesions with almost fluid density in the caudate lobe suggest liver cysts.
