An Unusual Presentation of Ovarian Metastasis of Colon Cancer Mimicking Hematoma

Öz

A 53 year-old female patient who was operated for adenocarcinoma of ascending colon having a recent history of anticoagulation therapy was diagnosed with a prominently cystic pelvic mass in close proximity to iliac arteries on CT. The differential diagnosis included metastatic lesion, organizing hematoma, primary ovarian neoplasm and pseudoaneurysm of the iliac artery. Excision of the lesion revealed ovarian metastasis of colon carcinoma. In the follow-up of a patient with colon cancer, a pelvic mass of any type should prompt consideration of metastatic cancer in the differential diagnosis

Kolon Kanseri Over Metastazının Hematomu Taklit Eden İlginç Prezentasyonu

Öz

Çıkan kolon adenokarsinomu nedeniyle opere edilmiş ve yakın geçmişte antikoagülan tedavisi hikâyesi olan 53 yaşındaki bayan hasta hastaneye ileus ile başvurmuştur. BT incelemesinde ilyak arterlere yakın komşuluk gösteren büyük ölçüde kistik pelvik kitle teşhis edilmiştir. Ayırıcı tanıda metastatik lezyon, organize hematom, primer over neoplazmı ve ilyak arter psödoanevrizması düşünülmüştür. Lezyonun eksizyonu kolon kanserinin over metastazı ile uyumlu olup, herhangi bir pelvik kitle ayırıcı tanısında metastatik kanser ayırıcı tanıda yer almalıdır.
