Abstract
INTRODUCTION: Venous malformations are congenital lesions that occur due to a defect in vascular embryogenesis. Intraosseous venous malformations involving long bones are quite rare, as evidenced by limited case reports and series available in the literature. CASE REPORT: We present one such case of a young female who presented with chronic pain in the leg for 2 years and difficulty in walking. The clinical and radiological evaluation, including computed tomography angiography, confirmed the diagnosis of intraosseous venous malformation of the tibia. The lesion was managed initially by sclerotherapy and endovenous laser ablation by the intervention radiologist; however, the bony lesion required prophylactic intramedullary nailing in view of persistent pain affecting her daily activities. CONCLUSION: The case highlights the rarity of the intraosseous venous malformation of long bones, which often results in misdiagnosis and requires a multidisciplinary approach in diagnosis and treatment for an optimal outcome.
