Pseudomyxoma Peritonei Presenting as Acute Appendicitis: Clinical and Imaging Findings

A 30-year old man presented with symptoms and signs of acute appendicitis. Abdominal imaging via ultrasound and computed tomography detected a mass in the right iliac fossa. Exploratory laparotomy revealed an appendiceal mass and gelatinous peritoneal fluid, while histopathology confirmed the diagnosis of pseudomyxoma peritonei arising from a mucocele of the appendix and attributed to an appendiceal cystadenocarcinoma. The clinical and imaging findings of this rare case are herein presented

Fungal infection of aortoiliac endograft: A case report and review of the literature

Infection of aortoiliac endografts is, to date, a rare complication of endovascular surgery. Staphylococcus species are the most common responsible pathogens, just as in cases with infected grafts after open aortic surgery. We report a case of a 65-year-old man with a history of diabetes mellitus and bladder cancer who developed stent-graft infection 3 years after endovascular treatment for a 5.6 cm abdominal aortic aneurysm. The diagnosis of endograft infection was established radiologically by computed tomographic scans. After intravenous administration of antibiotics and fluids to improve his clinical condition, the patient underwent surgical excision of the infected prosthesis and a bifurcated rifampicin-impregnated Dacron graft was placed in situ. Cultures from the purulent fluid around the aorta and from the endograft revealed development of Candida albicans. To our knowledge, this is the first case of an infected endograft due to a fungus. The patient died from septic shock 3 days postoperatively in the intensive care unit

Surgical management of extracranial internal carotid aneurysms by cervical approach

Background: Extracranial internal carotid artery aneurysms (EICAA) are rare vascular problems with a great potential for lethal thromboembolic episodes. Methods: From 1994 to 2004, nine patients with EICAA, seven men and two women, were surgically treated for 10 aneurysms in our department. Aneurysm led to hemispheric symptoms in six cases (two hemispheric strokes and four hemispheric transient ischaemic attacks). The cause was fibrodysplasia in two cases, atherosclerosis in four cases, trauma in two cases and spontaneous dissection in two cases. All aneurysms were treated surgically by the cervical approach using shunting. Extended cervical approach was necessary in four patients with high-lying aneurysms. Nine aneurysms were totally resected and successful revascularization was carried out. Open aneurysmorrhaphy with vein patch angioplasty was carried out in one case of a saccular aneurysm. Results: There were no perioperative deaths or transient ischaemic attacks or strokes. Four patients developed cranial nerve deficits: one had hoarsness, two had partial facial paralysis (patients with extended cervical approach) and one had tongue deviation. These neurological symptoms were observed in large aneurysms (> 4.5 cm) and disappeared within 14 months. No neurological complication was observed in a follow up that ranged from 6 months to 10 years. Conclusions: Surgical repair of EICAA, especially with total resection and arterial reconstruction, is strongly recommended. Extended cervical approach has many technical difficulties but can allow treatment of high-lying aneurysms
