Acute suppurative thyroiditis caused by Salmonella enteritidis.

Acute suppurative thyroiditis in a 47-year-old diabetic woman is reported. Diagnosis was suspected by clinical examination and confirmed by ultrasound, CT-scan and cytological examination. A rare causative agent was isolated--Salmonella enteritidis. No signs of nodular goiter or connection with piriform sinus were found. In spite of our efforts, the source and route of infection remained unclear. However, the haematogenic route seems to be the most plausible. Surgical drainage and antibiotics brought about a complete recovery. Partial lesion of the gland required transitory administration of levothyroxine.
