ABSTRACT

Many malignant process cause abdominal lymphadenopathy and computed tomography (CT) has become the primary modality for its detection. Diagnosis of lymphadenopathy is facilitated by optimal imaging techniques and knowledge of various nodal chains, their complex interactions and preferential pathways of spread. Optimal techniques include Imaging after oral administration of adequate amounts of hydrosoluble contrast and dynamic scanning after intravenous administration of contrast of the abdominal region. Although such technique help to prevent misdiagnosis due to normal and anomalous vascular structures, other benign diseases can mimic the CT appearance of malignant lymphadenopathy. Lymphadenopathy is defined as retrocrural nodes greater tan 6 mm in short axis, upper abdominal nodes greater than 10 mm and pelvic nodes greater than 15 mm.
