Solitary Splenic Metastasis from Rectal Cancer; A case report and literature review.

Abstract: Background: Metastasis to the spleen is rarely seen on imaging and has been little reported in the literature, requires for early diagnosis and a surveillance staging protocol to get a guide for management at the onset of metastatic diseases, and it can occur at the advanced stages of the disease or posttreatment follow-up evaluation. Case Presentation: A 59-year-old Saudi female patient diagnosed with rectal adenocarcinoma with metachronous metastatic hepatic and splenic lesions. Clinical examination of the abdomen was rigid with the development of splenomegaly. post-chemotherapy and laparoscopic-assisted diverting colostomy. She has high (CEA) markers and normal levels of hemoglobin. However, we knew she may relapse based on an advanced stage, thus, the progression of the disease was reported in the form of hepatic (82%) and splenic (46%) lesions. Conclusion: Splenic metastasis is an unusual entity, an incidental finding of radiological examination, requiring further investigation to confirm the malignant character. The standard method in therapeutic strategies for splenic metastasis has not been constituted. Known treatment options include splenectomy, chemotherapy, and radiotherapy.
