title: Isolated splenic metastasis from colorectal carcinoma in a high risk patient: a case report.
abstract: Isolated splenic metastasis arising from a colorectal carcinoma is a rare finding. We report a case of 74-year-old man with a medical history of diabetes type II and paroxysmal atrial fibrillation, who underwent a right hemicolectomy for an adenocarcinoma of caecum in August 2004. In June 2007 the patient was diagnosed with high grade aortic valve stenosis as well as long segment stenosis of the first obtuse marginal branch of left coronary artery. He was suggested aortic valve replacement with coronary artery bypass grafting but he refused the surgery. In October 2007 the patient underwent alpha 18FDG - PET scanning, due to increasing values of CEA serum level, which showed a 5 cm big isolated hypermetabolic lesion in the spleen. Due to operative risk, splenectomy was refused by surgeons. The patient underwent a chemotherapy with capecitabine in total of 8 cycles before his CEA level began to rise and MSCT showed a progression in size of splenic metastasis. The patients condition was reevaluated by a team of experts and splenectomy was performed in September 2008. In May 2009 during the postoperative follow up, MSCT scanning revealed enlarged lymph nodes in celiac region and hepatic lesion suspicious of metastasis and the patient was admitted for further chemotherapy treatment. There is still no standardized treatment for this condition due to small number of cases reported in literature. Splenectomy followed by chemotherapy seems to be an optimal treatment but still no final conclusions can be made.
