Diagnostic value of ultrasound in the evaluation of the echostructures of the nodular formation of the thyroid gland using the classification system TI-RADS

Objective. Estimation of the ultrasonographic criteria efficacy in accordance to the TI-RADS system while determining the morphological structures of nodal thyroid affections. Materials and methods. Results of ultrasonographic investigation in 546 patients, ageing 17 - 76 old and suffering thyroidal nodal affections, were analyzed. All the patients were divided into two groups. Into the firsr group (the main) 427 (78.2%) patients were included, to whom ultrasonographic investigation was performed by a surgeon-endocrinologist. Into the second group (the control one) 119 (21.8%) patients were included, to whom ultrasonographic investigation was performed by a radiologist. Ultrasonographic criteria with nodal thyroidal affections were estimated in accordance to the TI-RADS scale, and the results of cytological investigations of the nodal affections - in accordance to criteria of the Bethesda system. The degree of the malignant nodal affections risk was determined, taking into account a quantity of intranodal echographic signs in accordance to the points gradation, using a Ti-RADS system. Results. In accordance to results of pathohistological investigations of the removed specimen a benign changes were revealed in 128 (76.6%) patients, and malignant - in 39 (23.4%). In structure of malignant affections papillary cancer was established in 23 patients, follicular - in 13, medullary - in 2, Hurtle-cellular - in 1 patient. In accordance to cytological investigations, conducted in 2014 - 2018 yrs., there was established, that in the first group a fine-needle biopsy was conducted in 211/427(49.4%) patients. Operative interventions were performed in 105 (24.6%) patients. In the second group a fine-needle biopsy was performed in 64/119 (53.8%) patients. Operative intervention was conducted in 62 (52.1%) patients. Conclusion. While conduction of ultrasonographic investigation by a surgeon-endocrinologist the rate of revealing of false-positive echographic signs have lowered in more than 2 times (1.4%), comparing with analogous index while conduction of the investigation by radiologist (3.1%). Application of a TI-RADS classification have permitted to reduce the rate of the fine-needle biopsy and doing of surgical interventions.

Background and Aims. Several studies have shown the benefits of endoscopic ultrasound-guided fine needle biopsy (EUS-FNB) using a Franseen needle for histological assessment. However, studies focusing on pancreatic diseases are limited and the safety of this method has not been well assessed. We aimed to assess the current status and issues of EUS-FNB in the diagnosis of pancreatic diseases. Materials and Methods. We retrospectively reviewed 87 consecutive EUS-FNB specimens using either a 22-gauge Franseen needle (Group A, N = 51) or a conventional 22-gauge fine-needle aspiration needle (Group B, N = 36) for pancreatic diseases, and the diagnostic accuracy and safety were compared. Final diagnoses were obtained based on surgical pathology or a minimum six-month clinical follow-up. Results. Although the diagnostic accuracy for malignancy was 96.1% in Group A versus 88.9% in Group B, with no statistically significant difference (P = 0.19), the median sample area was significantly larger in Group A (4.07 versus 1.31mm2, P < 0.0001). There were no differences between the two needles in the locations from which the specimens were obtained. Adverse events occurred in one case (2%) in Group A (mild pancreatitis) and none in Group B with no statistical significance (P = 0.586). Although there was no case of bleeding defined as adverse events, 2 cases in Group A showed active bleeding during the procedure with increase in the echo-free space, which required CT scanning to rule out extravasation. Eventually, the bleeding stopped spontaneously. Conclusions. Given its guaranteed ability to obtain core specimens and comparable safety, and although the risk of bleeding should be kept in mind, EUS-FNB using a Franseen needle is likely to become a standard procedure for obtaining pancreatic tissue in the near future.

Ectopic thyroid tissue is seen rarely. It is often seen in cervical midline, and rarely in other areas such as submandibular area. Diagnosis is made histopathologically by fine needle biopsy after the elimination of malignancy. In the treatment of ectopic thyroid tissue, surgical excision is mostly applied. According to our knowledge, there is no exophytic thyroid tissue reported in the literature. In this paper, a 32-year-old woman who presented with a swelling under the right jaw and found a thyroid tissue attached to the normally located thyroid gland with a fibrous band in the neck was discussed.

Clinical Methods

At the ENT Clinic of the Regional Hospital in Örebro, cytological investigation of fine-needle biopsy specimens has been carried out to a steadily increasing extent for more than ten years as a complement to clinical methods of investigation and laboratory tests in cases of goiter. Evaluated here are the method's diagnostic accuracy and its value in investigatory work. The material consists of 303 patients with goiter who were operated from 1964 to 1971 following fine-needle biopsy. Cases where biopsy only was undertaken are not included. Assessable cytological material was obtained in 284 cases (94%). Although not less than 15 doctors carried out the fine-needle biopsies there was approximately a 93% agreement between the cytological and histological diagnoses. In 15 of 28 cases of thyroid carcinoma it was possible to make a definite diagnosis preoperatively, while in 12 of the remaining cases atypia suspected of malignancy was found. The possibility of being able to demonstrate or suspect a carcinoma preoperatively is of great importance for the surgeon, as a more extensive intervention can be planned in advance and the patient informed before the operation.

Follicular Tumor

The article is based on the treatment results of 44 patients with follicular tumor of thyroid gland. A staged morphological assessment of thyroid nodes was performed for all patients: in case of preoperative fine-needle biopsy, urgent intraoperative study and according to results of final histological research. The urgent histological study of surgical material was conducted for 44 patients with diagnosis «follicular tumor» according to fine-needle biopsy. The data of final histological study were matched with findings of intraoperative research. A micro-follicular adenoma was detected in 22 patients (50%) and 6 (13,6%) patients had this diagnosis combined with autoimmune thyroiditis. The general part of patients didn’t changed in final study, but the rate of diagnosis «micro-follicular adenoma against the background of autoimmune thyroiditis» increased. Papillary carcinoma was revealed in 5 (11,4%) patients and follicular cancer had 4 (9,1%) patients detected in intraoperative study and 3 (6,8%) more patients according to data of final research. The histopathologic feature of colloid goiter was observed in 7 (15,9%) cases and a part of such patients reduced to 6,8% during final study. One of the patients (2,3%) had final diagnosis «oncocytoma». In case of thyroid nodules detection the needle biopsy should be carried out regardless to the size of nodule. The authors recommended performing the surgery with the urgent histological study in case of undetermined histological report. The following surgical strate gy was specified by the results of the urgent histological report.
