Pheochromocytomas and paragangliomas are rare neuroendocrine tumors that arise from the chromaffin cells of the adrenal medulla or extra-adrenal tissues. These tumors are characterized by an excessive secretion of catecholamines, which are responsible for the clinical manifestation of the disease. Although most of these tumors are sporadic, underlying genetic abnormalities may be present in up to 24% of the cases.

We present the case of a 68-year-old male with a rapidly enlarging hepatic artery aneurysm related to type B aortic dissection extending into the coeliac axis, which presented unique difficulties due to its morphology and filling via the false lumen. Endovascular treatment involved stent-graft placement from the coeliac axis into the splenic artery with the intention of excluding the coeliac supply to the common hepatic artery.

Materials And Methods: Consecutive patients undergoing infrainguinal vein graft bypass from January 2008 to December 2015 were identified from the National Vascular registry and enrolled in a duplex surveillance program.
Penetrating aortic trauma is associated with high mortality rates. We report the case of a 24-year-old man who presented with a self-inflicted abdominal aortic penetration injury, resulting in a pseudoaneurysm. Rather uniquely, he was managed through prophylactic stenting to his abdominal aorta; this case was also rare in that there were remarkably no associated visceral injuries.

This case report describes sigmoid diverticulitis presenting as a right psoas abscess with a colocutaneous fistula. The report highlights the role of appropriate imaging and a high index of suspicion in anyone presenting with a discharging lumbar abscess, especially when the focus of infection may be from a contra-lateral source.
