Fig 1.
Venous contour irregularity witnessed in two patients.
A-C show soft tissue distorting the vessel (white arrows). D-F show focal vessel narrowing (black arrows). Tumor (T) and portal vein (*) are marked accordingly. All images taken from 3mm multiplanar reformation in the axial (A/D), coronal (B/E) and saggital (C/F) planes.
Table 1.
Distribution of tumor grading and adjuvant chemotherapy regimens is shown for the patient cohorts with/ without venous contour irregularity.
Table 2.
Distribution of tumor grading and adjuvant chemotherapy regimens is shown for the patient cohorts with tumor to vein contact ≤180°/>180°.
