Metastasis of Colon Cancer to the Accessory Spleen: A Case Report

초록

Distant metastasis to the spleen is extremely rare. To the best of our knowledge, metastasis to the accessory spleen based on pathological findings has only been reported in four patients in the English literature, including one each of ovarian cancer, transitional cell carcinoma, breast cancer, and uterine carcinosarcoma after surgery. Furthermore, among these reported cases, only two reports (one each of transitional cell carcinoma and uterine carcinosarcoma) presented imaging findings. In this study, we report a case of colon cancer metastasis to the accessory spleen without involvement of the spleen in a 58-year-old male patient, providing imaging findings. This case emphasized the importance of considering the possibility of metastasis to the accessory spleen in patients with malignancy.
