Objective: The factors that influence the acquisition of adequate samples during liquid-based cytology (LBC) remain unclear. This study aimed to identify factors that affect cytological adequacy in LBC after ultrasonography (US)-guided fine-needle aspiration (US-FNA) of thyroid nodules. Study Design: From January 2017 to May 2017, a single radiologist performed US-FNA to diagnose 112 thyroid nodules in 112 consecutive patients. Based on US findings after US-FNA, the size, location, position, composition, calcification, and vascularity of each nodule, as well as the US-based diagnosis, were investigated by the same radiologist. Blinded to US information, a single cytopathologist investigated cytological adequacy, cytological cellularity, and Bethesda category. Results: Of the 112 thyroid nodules, cytological adequacy was achieved in 91.1% (102/112). Thyroid nodules with sizes ≥20 mm or those that were predominantly cystic showed a higher rate of cytological inadequacy (p < 0.05). Thyroid nodule location, position, calcification status, and vascularity did not influence cytological adequacy, nor did US-based diagnosis (p > 0.05). Nodule composition or calcification significantly influenced cytological cellularity (p < 0.05), whereas nodule size, location, position, vascularity, and US-based diagnosis did not (p > 0.05). Conclusions: Most investigated factors did not influence cytological adequacy or cellularity.

Us Findings

We reviewed the US findings and the diagnostic yield of fine-needle aspiration biopsy (FNAB) for cytologic and microbiologic samples in 4 patients with pulmonary or pleural aspergillosis. All 3 apical Aspergillus abscesses were round, hypoechoic with irregular margins and one contained echo-densities with shadowing consistent with air. One pleural empyema was oval and hypoechoic. Cytology suggested inflammation in all cases and Aspergillus hyphae were detected in 2 of 4 aspirates. Culture of the aspirate was positive for Aspergillus in 3 of 4 cases, while one diagnosis was made after surgery. No complications occurred. Apico-pleural Aspergillus lesions are suitable targets for US-guided FNAB, thus avoiding more invasive methods. Our results suggest wider use of this procedure.

Introduction: Thyroid nodules are one of the most common diseases. Objectives: The aim of this study was to evaluate the correlation between fine needle aspiration (FNA) and intraoperative frozen section findings for thyroid disease patients. Patients and Methods: In this study, the FNA and intraoperative frozen section findings of 143 patients who were admitted to an educational hospital, Isfahan, Iran were collected and classified using these diagnostic methods during 2015. To find the correlation between FNA and intraoperative frozen section findings, statistical analysis was conducted using SPSS software version 16.0 (Chicago, IL). Results: Sensitivity and specificity of the positive FNA findings were 71% and 86.8%, respectively (P<0.001). The maximum concordance between FNA and intraoperative frozen section for papillary thyroid cancer was seen (P<0.001). Conclusion: In this study, a significant association between FNA and intraoperative frozen section of thyroid cancers, among our patients, however this finding requires further investigation by larger studies.

Needle Aspiration Cytology

The purpose of research was comparing the ultrasound (US) features and fine-needle aspiration cytology (FNAC) in detecting the thyroid nodules in clinical practice. A cross-sectional analytical study retrospectively reviewed the US and FNAC findings for a total of 170 thyroid nodules. The US features that we compared included echogenicity, calcifications, shape, halo and Doppler, between 2017 and 2018. Totally, 170 nodules of thyroid were studied, which contained 72 (42.4%) benign and 98 (57.6%) malignant thyroid nodules. The sonographic features were significantly associated with malignancy such as microcalcification (97.0%), hyperechogenicity (91.5%), wider than taller shape (98.0%), absent halo (90.9%) and positive Doppler (78.0%) (P < 0.01). The altogether accuracies of calcification, echogenicity, shape, halo, and Doppler were 0.96, 0.92, 0.97,0.82 and 0.82, respectively. Our data suggest that US features could be a good sonographic criterion for recommending FNA cytology with follow‐up thyroid sonography and FNA.
