Two Cases of Thyroid Hematoma Developing after a Core Needle Biopsy / 대한내분비외과학회지

ABSTRACT

Ultrasound guided fine needle aspiration (FNA) of thyroid nodules is a very common procedure. Its diagnostic adequacy rate is approximately 70%. The adequacy rate for core needle biopsy (CNB) is approximately 80%, so that it was significantly higher than that of FNA. CNB is clinically useful in selected patients when a prior FNA reading is nondiagnostic. Complications from FNA and CNB are rare. We report on two cases of a hematoma of the neck caused by thyroid CNB with a review of literature.
