A 37\u2010year\u2010old man originally presented to our hospital with two weeks of oral bleeding and two days of hematuria of unknown etiology. Workup showed severely prolonged prothrombin time and extremely low activity of coagulation factors II, VII, IX, and X, raising suspicion for vitamin K deficiency. His coagulation studies gradually corrected after daily administration of high\u2010dose intravenous vitamin K. An anticoagulant poisoning panel ultimately revealed high levels of brodifacoum rodenticide\u2014likely from rodent meat ingestion during his vacation to China 2\u2009months before. Our case highlights the importance of a thorough social and toxicologic investigation in patients with unexplained coagulopathy consistent with significant vitamin K deficiency.<\/jats:p>","DOI":"10.1155\/crh\/9981550","type":"journal-article","created":{"date-parts":[[2025,11,17]],"date-time":"2025-11-17T18:56:58Z","timestamp":1763405818000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Superwarfarin
