Journal of the Medical Association of Thailand. 1999 Jan; 82(1): 89-95http://imsear.searo.who.int/handle/123456789/44449Chotmaihet Thangphaet.Four cases of proved hemophiliac pseudotumors caused by intraosseous bleeding are reported. Five lesions were found at the uncommon locations involving the cranial vault, mandible, phalanx, distal femur and distal tibia. The conventional radiographic and computed tomographic findings are expansile osteolytic destruction, cortical thinning, partial breaking cortex or pathological fracture, and sometimes associated soft tissue mass. Ultrasonographic feature of one case at the phalanx shows cortical expansion and thinning contained mixed echogenicity in the medullary canal with soft tissue extension. T99m DTPA of one case at the distal femur shows increased vascular flow and uptake at right distal tibia and left distal femur.engAdolescentBone Diseases --etiologyFatal OutcomeHemophilia A --complicationsHumansInfantMaleHemophiliacs bone pseudotumors.Case Reports
