Typical manifestations of Hürthle cell adenoma of the thyroid on contrast-enhanced CT: A case report.

RATIONALE: Hürthle cell adenoma (HCA) of the thyroid is a rare thyroid tumor, and there are limited studies on the contrast-enhanced computed tomography (CT).

PATIENT CONCERNS: We report the case of a 63-year-old woman with gradual enlargement of the thyroid over 10 years.

DIAGNOSES: Preoperative contrast-enhanced CT revealed typical lesion characteristics of HCA, confirmed by postoperative pathology.

INTERVENTIONS: Left thyroidectomy and partial right thyroidectomy were performed on the patient after general anesthesia.

OUTCOMES: At follow-up of 12 months after surgery, the patient was in good health without recurrence.

LESSONS: The typical imaging features of HCA on contrast-enhanced CT are helpful for the early diagnosis of thyroid eosinophilic adenoma. This will provide an important basis for the preoperative diagnosis and treatment strategy of HCA of the thyroid in future.
