Bilateral Thrombophilia Discovered in a Young Child Misdiagnosed Initially with Osteoarthritis

Introduction: The occurrence of venous thrombosis in children is rare, often idiopathic and rarely a known etiology can be found, with sometimes a delay diagnostic in most cases.

Method: We report a case illustrating the difficulties of diagnosing phlebitis and a fairly rare etiology in an 11-year-old boy: the diagnosis of venous thrombosis on thrombophilia was made 12 days after the onset of pain in both lower limbs after an initial diagnosis of osteoarthritis or acute synovitis of the hip.

Conclusion: The diagnosis of thrombo-phlebitis should be considered in the presence of any persistent unexplained pain in a limb in children. Early diagnosis and effective anticoagulation are essential for the prevention of post-phlebitic syndrome.
