Anomalous and Parasitic Arterial Blood Supply in the Abdomen

Vascular radiology is useful in determining the location and extent of abdominal neoplasms. In evaluating these parameters, variants or anomalies of origin of certain vessels must be kept in mind in order to avoid incorrect localization of the lesion as well as a mistaken diagnosis of parasitic blood supply. True parasitic blood supply appears in two forms; the parasitic blood supply may be provided via anastomotic communications or by actual invasion of a contiguous structure or organ.
