Thaiarte N 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.
