Overview
CT
most desmoid tumors are well circumscribed masses, although in some cases they may appear more aggressive with ill-defined margins most are relatively homogeneously or focally hyperattenuating when compared to soft tissue on the non-contrast scan. most will demonstrate enhancement following administration of intravenous contrast.[1] The CT appearance of desmoid tumors depends on their composition. They may appear homogeneous or heterogeneous and hypo-, iso-, or hyperintense compared with the attenuation of muscles. The degree of enhancement after the intravenous administration of contrast medium is variable [1,5,7,8]. In this case, the mass showed attenuation equal to that of muscle, but after the intravenous administration of contrast medium, mild enhancement was demonstrated even in the delayed images.[2]
