Patient: 35 year old female |
History: 35 year old female: with papillary microcarcinoma was treated with 100 mCi I-131 and delayed whole body and spot images were obtained. |
Image Size:[small][as-submitted]
|
Findings: I-131 scan: There is a small focus of tracer uptake superior to the thyroid bed most likely residual thyroid tissue in the thyroglossal duct. Additionally, the whole body images demonstrate increased uptake projecting over the breasts bilaterally. The tracer avid foci in the chest are likely in the breasts as the foci rotate as anterior structures on the oblique images. Gadolinium enhanced T1WI: Small mass in the right side of the pituitary gland with delayed enhancement as well as minimal deviation of the pituiatary stalk consistent with a microadenoma. |
DDx: Increased breast/anterior chest wall uptake on I-131 study: 1. Lactating/breast feeding 2. Lung/chest wall thyroid cancer metastases 3. Prolactinoma |
Diagnosis: Prolactinoma |
