Complementary role of CT and ultrasonography in the diagnosis of desmoid tumor of abdominal wall

Seven desmoid tumors of anterior abdominal wall in three patients were scanned with ultrasound. These include one tumor in each of two patients and five tumors in another patient who had familial colonic polyposis (i.e. Gardner's syndrome). The tumors were echo-free and sharply and smoothly defined simulating cysts. CT on the patient with multiple masses, however, showed the density of the masses to be that of soft tissue. Combined ultrasonography and CT, a homogeneous tumor of abdominal wall such as desmoid can be suggested.
