CT scan and octreotide scan of an organ of Zuckerkandl paraganglioma

The images demonstrate an organ of Zuckerkandl paraganglioma (arrows) that extends from the just above the region of the inferior mesenteric artery (arrowhead, A) to the aortic bifurcation (dashed arrow, image C) for 12 cm. Images A, B, and C depict contrast-enhanced CT scan images of the same patient as seen in the axial, sagittal, and coronal planes, respectively. The affinity of the paraganglioma for octreotide is shown in the indium labeled nuclear medicine scan (image D). The mass is well defined with absent or delayed central contrast enhancement on the CT scans (images A, B, and C).
