Apathetic thyrotoxicosis due to hemorrhage into a hyperfunctioning thyroid nodule after excessive anticoagulation.
Southern Medical Journal
|May 1, 1985
Summary
A large, hyperfunctioning thyroid nodule in an elderly woman led to thyrotoxicosis after bleeding into the nodule. Symptoms resolved spontaneously within a month without treatment, as confirmed by ultrasound and thyroid scans.
Area of Science:
- Endocrinology
- Thyroidology
Background:
- A 72-year-old woman presented with a diagnosed hyperfunctioning thyroid nodule.
- The nodule grew to 3.5 cm in diameter.
Observation:
- Hemorrhage into the nodule occurred during excessive anticoagulation.
- This precipitated overt thyrotoxicosis, specifically the apathetic type.
Findings:
- All abnormal physical signs, symptoms, and laboratory findings normalized within one month.
- No specific medical or surgical treatment was required for recovery.
Implications:
- This case highlights the potential for spontaneous resolution of thyrotoxicosis precipitated by nodular hemorrhage.
- Ultrasound and thyroid scintigraphy are valuable tools for monitoring such cases.
