A splanchnic venous thrombosis revealing Biermer's disease: A case report.

Background: The relationship between Biermer's disease and increased thrombotic risk, while uncommon, represents a critical clinical concern necessitating heightened diagnostic awareness for patients presenting with unexplained thrombotic symptoms. Case presentation: This report details the case of a 57-year-old male, with a prior diagnosis of Graves' disease, who developed splanchnic venous thrombosis. An extensive etiological investigation revealed mild hyperhomocysteinemia, associated with an undiagnosed Biermer's disease. Conclusions: Our case underscores a critical association between Biermer's disease, hyperhomocysteinemia, and venous thrombosis, emphasizing the imperative for further research elucidating their interconnected pathogenesis.
