Intraosseous hemangioma is accounting for about 0.7% of all bone tumors. It is considered as rare bone tumor. It can present at any age; however, it is commonly seen between fourth and fifth decades.1
The cause is unknown; it could be congenital or traumatic. 2
Patient may present with slow growing palpable hard mass as in our case with mild tenderness. Neurological deficit is uncommon as mass grows externally rather than internally.3
Radiologically interosseous hemangioma presented as osteolytic lesion. CT is the modality of choice to check interosseous extent and soft tissue involvement; however, it is difficult to make definitive diagnosis radiologically only, as many differential diagnosis may be raised like langerhans cell histiocytosis, osteoma and fibrous dysplasia.4
In CT fibrous dysplasia will show ground glass appearance which may help to differential between it and interosseous hemangioma which will show thickened trabeculae with sunburst pattern.
Treatment of choice is en bloc resection with safe margin of normal bone. Other therapies like embolization, curettage and radiotherapy may help.4
