Expanded dengue syndrome are unusual conditions, such as subacute thyroiditis (SAT). We present the case of a 38-year-old woman who had dengue without alarm signs for a month, along with cervical pain and increased cervical volume, palpitations, tremor and dysphagia. Hormonal evaluation, ultrasound and thyroid scintigraphy were consistent with SAT. She received corticoids for two months, with remission after four months. SAT is characterized by neck pain, fever and symptoms of thyrotoxicosis. It is associated with viral infections and it comprises a phase of thyrotoxicosis followed by hypothyroidism. Diagnosis involves hormonal and biochemical tests, thyroid ultrasound with Doppler and scintigraphy. This condition is managed with non-steroidal anti-inflammatory drugs and corticosteroids, according to severity. SAT, an infrequent manifestation of dengue, requires a high degree of suspicion and appropriate management. A review of published cases of SAT due to dengue was carried out in the Scopus, PubMed and Web of Science databases, finding six reported cases, mostly in men.
