Case of the Week from 11/15/20
History: Endometrial cancer.
Describe the findings. Moderate hypermetabolic lesion at the left thyroid lobe without anatomically evident nodule on CT scan.
What is the differential/most likely diagnosis? Most likely thyroid adenoma. Differential includes primary thyroid cancer.
What do you need to do next? Recommend thyroid ultrasound for further anatomic characterization since thyroid ultrasound is more sensitive for thyroid nodules than CT scan.
What do you do if there are no findings on CT and positive findings on FDG-PET? Recommend thyroid ultrasound. If a nodule is anatomically present at same location on ultrasound, recommend biopsy because of higher risk of cancer in hypermetabolic nodules.

History: Hip pain.
Describe the findings.
What is the differential/most likely diagnosis? Multiple hereditary exostoses.
