Thyroiditis is a rare cause of fever of unknown origin (FUO). This case highlights thyroiditis presenting solely with fever and weight loss, confirmed by thyroid scintigraphy.
Area of Science:
- Endocrinology
- Nuclear Medicine
Background:
- Fever of unknown origin (FUO) presents a diagnostic challenge.
- Thyroiditis is an uncommon etiology for FUO.
Observation:
- A patient presented with unexplained fever and significant weight loss.
- Initial investigations for FUO were inconclusive.
Findings:
- Thyroid scintigraphy revealed findings consistent with thyroiditis.
- Thyroiditis was confirmed as the cause of the patient's symptoms.
Implications:
- This case underscores the importance of considering thyroiditis in the differential diagnosis of FUO.
- Thyroid scintigraphy is a valuable tool for diagnosing thyroiditis in the context of FUO.
