Cystic thyroid nodules are considered to be one of the major causes of nondiagnostic and false-negative results on conventional fine-needle aspiration biopsy, thus limiting the potential of this method for the evaluation of complex (solid-cystic) thyroid nodules. Although ultrasound-guided fine-needle aspiration biopsy has emerged as a highly effective diagnostic method for the assessment of nonpalpable and difficult to palpate nodules, its role in complex nodules has not yet been carefully evaluated. In this study, we report the efficacy of ultrasound-guided fine-needle aspiration biopsy in 124 complex nodules in 113 patients. This method proved to be highly effective, yielding a satisfactory specimen for cytological evaluation in 94% of the nodules, suggesting that it is an excellent modality for the evaluation of complex nodules and also for the reevaluation of those nodules with a nondiagnostic result on conventional fine-needle aspiration biopsy.

Objective. The prevalence of thyroid nodularity in children has been estimated to be 1.8%. The reported prevalence of specific diseases which comprise these nodules is conflicting as evidenced by a reported range of malignancy of 2 to 50% in solitary nodules. In order to better classify pediatric (<18 years old) thyroid disease and evaluate the utility of fine needle aspiration biopsy (FNAB) in this patient population, we retrospectively reviewed 66 FNABs from 64 thyroid nodules and 2 perithyroid lymph nodes from 57 patients. Methodology. Patients: The study was composed of 8 males and 49 females who ranged in age from 1 to 18 years old (mean = 13.1). Design: Surgical and/or clinical follow-up was obtained in all patients. The 66 FNAB diagnoses were initially classified into specific diseases. However, for the purpose of this review, the cases were classified as: 3 insufficient, 51 benign, 8 suspicious, and 4 malignant. Results. There were no "false positives" and one "false negative" (a papillary carcinoma was misdiagnosed as a benign nodule). Overall, 10 patients (18%) had malignant thyroid lesions, including 8 papillary carcinomas and 2 follicular carcinomas. Benign diagnoses included benign nodule, cyst, lymphocytic thyroiditis, granulomatous thyroiditis, hyperplasia, and abscess. Conclusions. The prevalence of malignancy in pediatric patients with thyroid nodules was 18%. We conclude that, because of its high diagnostic accuracy and minimal invasiveness, FNAB is useful in the management of pediatric thyroid nodules.

Background. Fine-needle aspiration biopsy is the most important procedure for differentiating benign thyroid nodules from malignant ones. Traditionally, findings of fine-needle aspiration biopsy are divided into four categories: nondiagnostic, benign lesions, suspected cancer, and malignant lesions. Group suspicious for cancer largely involves follicular neoplasms as well as lesions with cytological features of malignancy. Objective. The purpose of this study was to establish the value of ultrasound-guided fine-needle aspiration biopsy in the diagnosis of nonpalpable thyroid cancer and to assess the frequency of malignant disease in the group of suspected cancer. Patients and methods. A total of 184 patients with nonpalpable thyroid nodules (less than 1.5 cm in diameter) were examined by means of ultrasound-guided fine-needle aspiration biopsy. Patients were included in the study based on sonographic findings implicating possible malignant nature of nodules. Results. During 1997–2002, 204 ultrasound-guided fine-needle aspiration biopsies of thyroid nodules were performed; findings were nondiagnostic in 5.9% of cases. In 59.8% of cases, cytological examination revealed benign lesions; in 11.8%, suspected cancer; and in 22.5%, malignant lesions. Eighty-five patients underwent subsequent surgery with histological examination of specimens obtained. In 45 cases, cytological diagnosis of malignant or suspected thyroid cancer was confirmed by histological examination after surgery. Conclusion. We conclude that ultrasound-guided fine-needle aspiration biopsy has a high accuracy in the diagnostic evaluation of nonpalpable thyroid nodule with cytological features of malignancy. However, fineneedle aspiration biopsy is not effective diagnostic method for differentiating benign thyroid nodules from malignant ones in follicular neoplasm group.
