A 79 years old woman presented in a peripheral hospital with dyspnea, right-sided pleuritic chest pain and cough for 3 days. On examination, she was tachycardiac and tachypneic. She had reduced air entry bilaterally on auscultation. Computed tomography-pulmonary angiogram, performed in peripheral Hospital, confirmed the diagnosis of pulmonary embolism, and she was commenced on warfarin. Ultrasonography showed no evidence of deep venous thrombosis in legs; however, ultrasound of the abdomen revealed an aortic aneurysm. She was hemodynamically stable on transfer to vascular surgery department, and her complete clinical examination revealed a pulsatile mass in the central abdomen. Computed tomography angiogram of aorta showed 8.7-cm abdominal aortic aneurysm. Venogram performed during inferior vena cava (IVC) filter insertion showed that IVC was displaced and compressed due to this large aortic aneurysm, causing thromboembolism. An open repair of the aneurysm was performed with uneventful recovery.

This case describes a 60-year-old gentleman who presented with a pulsating mass behind his knee. Before this, he had a fasciotomy for suspected compartment syndrome of leg following knee arthroscopy, but this failed to resolve his leg symptoms. He was hemodynamically stable on presentation. His left calf was swollen with a circumference of 3 cm greater than right. There was a large pulsating mass palpable in his left popliteal fossa. Distal neurovascular status of the leg was intact. He had a normal cardiovascular, respiratory, abdominal and neurological examination. Ultrasound showed a cystic mass in the popliteal fossa suggestive of aneurysm. CT angiogram demonstrated a 6 × 5 × 4 cm pseudoaneurysm compressing and displacing the left popliteal artery with satisfactory three-vessel run-off. An emergency repair was performed. An arteriotomy was identified at the proximal end of pseudoaneurysm and it was closed with a patch of small saphenous vein. It led to a good clinical outcome.

SUMMARYA 20-year-old woman with a functioning ventriculoperitoneal (VP) shunt consistently reported unbearable vertex headaches and nausea during the last hour of her haemodialysis (HD) sessions. After one particularly severe episode, which was associated with vomiting, restlessness and blurred vision, her team suspected that she was developing dialysis disequilibrium syndrome. She improved fully on cessation of HD, requiring simple analgaesia only, and continued dialysis three times per week. Several more distressing episodes of nausea and headaches compelled us to give intravenous mannitol during HD, resulting in temporary improvement. Subsequently, shorter and more frequent dialysis sessions along with intravenous mannitol resulted in satisfactory clinical response. BACKGROUND
