Worsening confusion and tachycardia (heart rate >180 bpm) prompted ICU consultation and further evaluation. Although the patient did not have overt signs of an underlying thyroid disorder, (exophthalmos, lid lag, goiter), laboratory work confirmed the suspicion of thyroid storm with TSH of <0.1 uIU/ml (normal 0.35-5.50 uIU/ml), T3 of 783.7 ng/dl (normal 60-181 ng/dl), and free thyroxine of 5.8 ng/dl (normal 0.9-1.8 ng/dl). Propranolol and Methimazole were begun. Final cultures were negative and antibiotics were discontinued. Patient’s symptoms resolved with the above treatment and her thyroid functions improved (T3 447.2 ng/dl, Free T4 4.6 ng/dl). Her leukocytosis and lactic acidosis resolved. Further immunological work-up revealed an undiagnosed Graves’ disease with high titres of Anti-TSH antibodies.
Discussion: Thyroid storm is a decompensated state of thyrotoxicosis with a reported fatality rate of 20-30%. Recognition of thyroid storm can be difficult, because signs and symptoms are non-specific, as seen in the above patient. It may mimic other severe illness such as acute abdomen. Our patient did not have a history of thyroid disease or typical examination findings of hyperthyroidism.
Abdominal pain of recent onset can be a challenging clinical problem. The triad of fever, abdominal pain and confusion should be fully evaluated for intra-abdominal sepsis due to bacterial contamination or chemical irritation, mechanical obstruction of hollow viscera, vascular disturbances such as embolism or thrombosis, as well as metabolic causes such as diabetic ketoacidosis and thyroid storm.
- Thyroid storm should be considered in the differential diagnosis of patients presenting with acute abdomen and signs of sepsis.
- Any patient presenting with fever, tachycardia and confusion needs prompt, thorough evaluation in an attempt to rapidly identify and treat the cause of the symptoms.
- The purpose of this case report is to alert clinicians about atypical thyrotoxicosis presentations which, if overlooked, can rapidly progress to life-threatening multi-organ failure.
