We report on a rare case of an intra-osseous haemangioma involving the medial portion of tibia in a 29-year-old man.

The aim is to emphasize on diagnosis difficulties, possible recurrence and interest of sclerotherapy. In radiographs, the lesion was a well-defined osteolytic lesion having 3 mm of diameter with perimeter’s sclerosis. The computed tomography images demonstrated an intra-medullar gap’s image of the tibia with cortical participation. An osteoid osteoma was evocated but eliminated by the histhological examination. The osseous scintigraphy didn’t find any anomaly. The outcome was marked by the recurrence of pain. T1-weighted Magnetic resonance imaging showed a hypointense lesion, while T2-weighted images revealed hyperintense areas, with internal, hypointense septa. Gadolinium-enhanced T1-weighted images showed lattice-like enhancement of the lesion. These images signed a recurrence of the intra-osseous venous haemangioma. The sclerotherapy improved the pain in three days and prevented another recurrence.展开更多
