[Aneurysms of the visceral arteries: the diagnostic problems and therapeutic strategies].

Intestinal artery aneurysms are a rare clinical condition, usually asymptomatic. However, sometimes they occur as vascular emergency, with a mortality rate of about 75%. Therefore, their occasional diagnosis should be carefully considered as an indication for elective surgery. The authors report their experience in the surgical management of 3 cases of intestinal artery aneurysms respectively involving the splenic, the gastroduodenal and the inferior mesenteric artery. A review of the literature is also presented.

[Primary intrahepatic calculosis: hepatic lithotomy or hepatectomy?].

The authors discuss about the different surgical approaches in the management of primary intrahepatic stones, conforming their experience to literature reports. In the future they hope for a more conservative treatment on the basis of the good results obtained with percutaneous transhepatic fiber cholangioscopy (P.T.C.S.) and ultrasonographic extra-body lithotripsy recently adopted in the clinical practice.

[Abdominal tuberculous lymphadenitis simulating pancreatis cancer].

The Authors report the case of a patient symptomatic for fever, weight loss and abdominal pain submitted to abdominal sonography and CT which identified a mass of the pancreatic head. The patient underwent laparotomy plus biopsy; the istologic and bacteriological diagnosis demonstrated a tuberculous lymphoadenitis in spite of a normal cutaneous tuberculin test. Abdominal localization of TBC infection therefore is increasing in epidemiological studies, and thus it must be included in the differential diagnosis of subdiaphragmatic disease.
