title: Regional bone change in intramuscular haemangioma mimicking primary bone tumour.
abstract: Intramuscular haemangiomas are benign soft-tissue tumours, commonly located in the extremities. We present a right-leg intramuscular haemangioma with florid periosteal reaction in adjacent tibia, mimicking a primary bone tumour. Plain radiograph and magnetic resonance imaging features are illustrated with the surgical and histopathological findings. Radiologists need to be familiar with reactive bone changes secondary to deep-seated intramuscular haemangiomas to avoid potential misdiagnosis.
