Rectal Cancer in the Eye: A Case Report of Orbital Metastasis

Abstract

Orbital metastasis from colorectal cancer is extremely rare. In this case report, we describe a 48-year-old woman who presented with recurrent severe headaches and new onset constipation with no known history of cancer. After vigilant workup, imaging, and biopsies, she was diagnosed with orbital metastasis from a primary rectal carcinoma. She was started on chemotherapy and radiation therapy. Her chemotherapy regimen consisted of FLOX (leucovorin + fluorouracil + oxaliplatin), along with panitumumab, which she tolerated well. She received chemotherapy for seven months before she lost her battle with cancer.
