Clinical History
Case of newly diagnosed thyroid ca for staging with PET/CT.
Findings
A mildly FDG-avid 18mm nodule is noted in the isthmus and adjacent right thyroid lobe (maxSUV 3.5).
No FDG-avid cervical, supraclavicular or mediastinal nodes are noted. The non FDG-avid tiny subcentimeter bilateral level II, left level III jugular/cervical nodes and precarinal node are more in favour of reactive nodes.
A dedicated brain study was not performed. No abnormal FDG avid focus is noted in the cerebral hemispheres or cerebellum.
No FDG-avid focus or nodule is seen in the lungs. No pleural effusion or pericardial effusion is noted.
There are no FDG-avid intra-abdominal or retroperitoneal nodes. No abnormal FDG-avid focus is noted in the liver, spleen, pancreas or adrenal glands.
The bone marrow shows normal physiological distribution of FDG activity.
Clinical Impression
A mildly FDG-avid thyroid nodule is noted.
The non FDG-avid tiny subcentimeter bilateral level II, left level III jugular/cervical nodes and precarinal node are more in favour of reactive nodes.
There are no FDG-avid metastatic foci detected.
