title: Computed tomography and ultrasonography of the hemophilic pseudotumor and their use in surgical planning.
abstract: Twenty-one hemophilic pseudotumors in 17 patients were evaluated radiologically to facilitate surgical planning. Plain radiography, angiography, intravenous urography, computerized tomography (CT), and ultrasonography (U/S) were the modalities used. CT proved to be the most efficient method in the detection of bone destruction and soft tissue lesions including additional daughter cysts. The combination of CT, intravenous urography, and angiography were used in pelvic pseudotumors, and that of CT and angiography for extremity pseudotumors, to determine the proper surgical approaches to the lesions. As a non-ionizing technique, U/S was usually preferable in visualizing soft tissue masses and, in sequential studies, to evaluate progress or recurrence of the lesion.
