An Analysis of Computed Tomography Imaging Features and Predictive Factors for Postoperative Recurrence and Metastasis of Abdominal Paragangliomas

Figure 3

One case of a 65-year-old female that had a slightly higher-level CA199, CA125. (a) Noncontrast CT scan showed an irregular tumour size of about 140 × 81 mm with heterogeneous low density in the retroperitoneal. The lesion presence multiple punctate strip calcifications. (b, c) Contrast-enhanced CT scans depicted heterogeneous nonsignificant enhancement. The CT values of the noncontrast, arterial, and venous phases were 43, 67, and 65 HU. The postoperative CT diagnosis was paraganglioma and (d) liver multiple metastasis (arrow) occurred.
