Abstract
This paper deals with two recent cases of Inferior Caval Vein (IVC) duplicity, congenital anomaly often but not always asymptomatic that should be considered in the differential diagnosis of flank pain when other more common disorders have been excluded. Here are described the clinical and surgical significance together with the typical sonographic findings useful for the diagnosis of IVC duplicity. Particular attention is given to a peculiar and easily repeatable sonographic aspect associated with IVC duplicity, not previously reported in Literature and that we called the “Neptune’s sign”.
Sommario
In questo lavoro vengono riportati 2 recenti casi di duplicità della Vena Cava Inferiore (VCI) che è un'anomalia congenita spesso, ma non sempre, asintomatica e che deve essere considerata nella diagnosi differenziale di dolore al fianco, quando le altre cause più comuni sono state escluse. Oltre all' importanza clinica e chirurgica della duplicità della VCI ne vengono descritti gli elementi ultrasonografici utili per la diagnosi. Particolare attenzione è dedicata ad un aspetto ecografico peculiare, facilmente ripetibile, associato con la duplicità della VCI e non precedentemente riportato in letteratura che abbiamo chiamato il "segno di Nettuno".
