Rationale: An accessory thyroid gland (ATG) in the right ventricle is an extremely rare condition. Described herein are histological findings of ATG in the right ventricle found in a patient with a normal cervical thyroid gland.
Patient concerns: A 53-year-old woman was referred to our hospital after experiencing intermittent precordial pain for 2 years.
Diagnoses: The mass in the right ventricle was diagnosed pathologically as ATG.
Interventions: Complete excision was performed because of the patient's intermittent precordial pain and to exclude the possibility of malignancy.
Outcome: The patient's pain was resolved. No recurrence was observed during the 6-month follow-up.
Lessons: After review and analysis of the case, we found that plain and contrast-enhanced computed tomography scans showed that the mass had a similar intensity and enhancement to a cervical thyroid gland, which we think may be a useful clue for making a preoperative diagnosis of ATG.
