Thyroid Cancer Case 03

Clinical History
71-year-old female was referred for a PET/CT scan for primary staging of thyroid cancer.

Imaging Findings
STATED REASON FOR REQUEST: Staging thyroid cancer
TECHNIQUE: Emission scanning from the neck through the pelvis was obtained approximately 90 minutes post injection, with a reduced scan time of 1 minute per PET bed position.

PET/CT FINDINGS: The PET/CT study showed a large hypermetabolic neck mass with multiple necrotic areas. There were multiple tracer avid metastases in the vertebrae, pelvis, and ribs, as well as in lungs, Iliac nodes and paravertebral muscle.

The high image quality, even with a reduced scan time of 1 minute per bed position, allowed the delineation of small lesions in the vertebral pedicle, lung, pelvis and ribs, as well as the necrotic areas within the primary thyroid mass. This aided the physician in correctly staging the patient and guided therapeutic decisions.
