An unusual cause of intramedullary bone cysts – Congenital afibrinogenemia

Solitary bone cysts have a wide range of differentials, but when there are numerous bone cysts involving multiple bone sites, a systemic hematological disorder would be the leading differential. We intend to highlight the multimodality imaging findings of multiple intramedullary bone cysts occurring as a rare complication of congenital afibrinogenemia. Intraosseous hemorrhages occur due to altered clotting mechanisms which later lead to formation of cysts.
