Overview
CT scan can be done in order to define the relationship of desmoid tumor to adjacent structures, assess resectibility and find out the need for treatment. On CT scan, desmoid tumor is characterized by a homogeneously or focally hyperattenuating well circumscribed mass which may demonstrate enhancement following administration of intravenous contrast.
CT
- CT scan is done to in order to:
- Define the relationship of the tumor to adjacent structures
- Assess resectability
- Find out the need for treatment
- CT scan may be diagnostic for desmoid tumor. On CT scan, desmoid tumor is characterized by a well circumscribed mass that may:
- Appear homogeneous or heterogeneous
- Hypo-, iso-, or hyperintense compared with the attenuation of muscles
- Appear more aggressive with ill-defined margins
- Be homogeneously or focally hyperattenuating when compared to soft tissue on the non-contrast scan
- Demonstrate enhancement following administration of intravenous contrast[1][2]
