An 88-year-old female presented with dyspnea on exertion and severe anemia. Colonoscopy was unremarkable and the patient was transfused with packed red blood cells prior to discharge. The patient returned 2 weeks later with severe abdominal pain, hypotension, and anemia. Computed tomography revealed splenic hematoma and hemoperitoneum. She bled from the surgical sites during emergent splenectomy and work-up revealed hemophilia A. We present, to our knowledge, a case of the longest reported delay in presentation of post-colonoscopy splenic rupture and the first in a patient with hemophilia A.
