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.<ref name="EconomouPitta2011">{{cite journal|last1=Economou|first1=Athanasios|last2=Pitta|first2=Xanthi|last3=Andreadis|first3=Efstathios|last4=Papapavlou|first4=Leonidas|last5=Chrissidis|first5=Thomas|title=Desmoid tumor of the abdominal wall: a case report|journal=Journal of Medical Case Reports|volume=5|issue=1|year=2011|pages=326|issn=1752-1947|doi=10.1186/1752-1947-5-326}}</ref>

Overview

CT

CT scan may be diagnostic for desmoid tumor. On CT scan, desmoid tumor is characterized by:

  • Well circumscribed mass, although in some cases it may appear more aggressive with ill-defined margins.
  • Homogeneously or focally hyperattenuating when compared to soft tissue on the non-contrast scan.
  • Most will demonstrate enhancement following administration of intravenous contrast.[1][2]
