Computed Tomography Features of Appendiceal Metastasis in Patients With Underlying Malignancy: Comparison With Pathological Findings

Objective: To evaluate the computed tomography (CT) findings compared with pathologic features and to determine whether CT findings are useful for diagnosis of appendiceal metastasis in patients with underlying malignancy. Materials and Methods: Preoperative CT examinations of 59 patients who had underlying malignancy and underwent appendectomy were evaluated. Appendiceal metastasis (n = 21) and nonmetastasis (n = 38) were pathologically confirmed. Computed tomography features (appendiceal morphology and diameter, presence of ascites, rectal shelf, omental cake, lymphadenopathy or organ metastasis) were retrospectively reviewed, and compared with histopathological findings. Fisher exact test and Wilcoxon rank sum test were performed for statistical analysis. Results: Mean diameter of appendiceal metastasis was significantly larger (9.1 mm) than that of nonmetastasis (5.2 mm), (P
