[67 Ga-citrate scintigraphy as a determiner in the diagnosis of a subacute thyroiditis]

Area of Science:

• Endocrinology
• Nuclear Medicine
• Internal Medicine

Background:

• A 41-year-old male presented with fever and toxic syndrome, prompting investigation for oncological or infectious causes.
• Initial diagnostic imaging was crucial for differentiating potential serious underlying conditions.

Observation:

• A whole body scan using 67Ga-citrate demonstrated intense and diffuse radiotracer accumulation specifically within the thyroid gland.
• This finding in the thyroid gland prompted further specialized thyroid imaging.

Findings:

• Subsequent thyroid scintigraphy with 99mTc-pertechnetate and radioiodine uptake studies were performed.
• These investigations led to the definitive diagnosis of painless subacute thyroiditis.

Implications:

• This case highlights the importance of considering less common diagnoses, such as subacute thyroiditis, even with severe initial symptoms.
• Accurate diagnosis through targeted nuclear medicine imaging is essential for appropriate patient management and treatment.
• Nuclear imaging plays a vital role in diagnosing inflammatory thyroid conditions.
