Question:

What are the roles of CT and/or MR imaging?
1. Evaluation of site and size
2. Relationship between the lesion and surrounding structures
3. Diagnosis of desmoid tumors
4. Differential diagnosis with other solid masses
5. Planning surgical resection and predicting prognosis





Answer:

The correct answers for the question "What are the roles of CT and/or MR imaging?" are:

1. Evaluation of site and size

2. Relationship between the lesion and surrounding structures

5. Planning surgical resection and predicting prognosis



Explanation
1) CT and/or MR are useful in evaluation of site and size (CT and MR imaging are useful techniques in the evaluation of the size, site, extent, and relationship between the lesion and surrounding structures, so they are useful in planning surgical resection and predicting prognosis)

2) CT and/or MR are useful in evaluation of relationship between the lesion and surrounding structures (CT and MR imaging are useful techniques in the evaluation of the size, site, extent, and relationship between the lesion and surrounding structures)

3) Final diagnosis is only by biopsy (A definitive diagnosis based solely on imaging features is not possible)

4) Differential diagnosis with other solid masses is not possible by CT and/or RM appearance (There are no specific imaging features on MR or CT to distinguish desmoid tumors from other solid masses)

5) CT and MR imaging are useful in planning surgical resection and predicting prognosis (CT and MR imaging are useful in planning surgical resection and predicting prognosis)

Abstract
Gardner syndrome is an autosomal dominant disease characterized by the presence of colonic polyposis, osteomas and soft tissue tumors. We present a case of a man who was admitted for a relapse of adenocarcinoma of the rectum. CT-staging showed multiple locations of desmoid tumors and osteomas, with final diagnosis of Gardner syndrome. The follow-up CT, after surgery and chemotherapy, showed a relapse of the lesions with hydronephrosis due to ureteral compression.
