|Patient: 53 year old male|
|History: 53-year-old male with papillary thyroid carcinoma status post thyroidectomy 09/01/2006 and I-131 100 mCi treatment dose 09/22/2006. Patient also with history of alpha-1-antitrypsin disease.|
|Findings: 1. Mild increased radiopharmaceutical activity within the thyroidectomy post-operative bed, consistent with residual thyroid tissue.|
2. Increased activity within the middle mediastinum and hilar regions. This appears to follow the course of the tracheobronchial tree. Given the patient's history of alpha-1-antitrypsin disease, this may represent retained secretions related to poor mucus clearance.
|DDx: Residual mucous contamination due to poor mucociliary clearance from alpha-1-antitrypsin deficiency. Diffuse metastatic disease involving the tracheobronchial tree is unlikely.|
|Diagnosis: Residual functioning thyroid tissue within the thyroid bed.|
Retained uptake within the tracheobronchial tree due to poor mucociliary clearance from alpha-1-antitrypsin deficiency.
