“…Different workers reported that failure to aspirate from proper site was the major cause of misdiagnosis during cytological evaluation. Also, high inadequacy rate, (ranging from 6.4 to 32.4%) as found in various studies; is another major limitation of conventional FNAC [2] .…”

“…It is useful, especially in cystic and multinodular lesions harbouring malignancy [3] . Also, Differentiating benign from malignant thyroid disease is of great importance for deciding on medical versus surgical management [2] . USG localization of thyroid lesions followed by USG-guided FNAC of palpable thyroid nodules has been suggested to reduce the rate of non-diagnostic material and subsequently reduce the false-negative interpretation.…”

Introduction: USG guided FNAC of thyroid particularly facilitates accurate FNAC of non-palpable small lesions. It has the major advantage of real time monitoring which help in accurate localisation of needle tip during aspiration. It is very useful in the non diagnostic or unsatisfactory cases (according to Bethesda System Bethesda category I). It has been suggested to reduce the rate of non-diagnostic material and subsequently reduce the false-negative interpretation. Aims: 1) To evaluate the Diagnostic accuracy of USG-guided FNAC of Thyroid. 2) To evaluate cellular yield of aspirated material in USG-guided FNAC. Materials and Methods:The present study included 100 patients with thyroid swelling undergoing USG guided FNAC who previously were diagnosed by FNAC as Non diagnostic or Unsatisfactory (According to Bethesda System Bethesda category I). USG guided FNAC was done & Smears were made. Then microscopy was done following the Bethesda system (TBS). Result: Total 100 patients with thyroid swelling undergoing USG guided FNAC who previously were diagnosed by FNAC as Bethesda category I. In present study, Out of 100 patients, maximum no. of patients were in 41 to 50 years age groups (54 cases) and majority were Female (84 Cases). The revised diagnosis in these cases according to TBS were as follow, Nodular goiter (29%), Colloid goiter (26%), lymphocytic thyroiditis (14%), Hashimoto thyroiditis (9%), Graves' disease (2%) & granulomatous thyroiditis (1%). Suspicious for malignancy (4%) and papillary carcinoma (4%) and Follicular neoplasm (3%). There was increased cellular yield of aspirated material in 92% of cases with USG guidance. In present study false negative & True Positive rates were-92% & 8% for Conventional FNAC technique, as concluded after repeat FNAC under USG guidance.

Objective: Among imaging modalities, ultrasonography (US) is one of the most versatilechoice, with its low cost, lack of radiation exposure, and minimally disrupted surgery flow.We described the use and characteristics of intraoperative ultrasonography (US) in selectedcases in our center to assist the intracranial tumor resection. Methods :Seventy patients wereoperated from 2011 to 2018 at Kariadi Hospital with the help of intraoperative US. Fifty sixpercents of cases were cystic tumors, 25% were abscess and 19% were metastatic tumors Weused seven parameters to measure the utility of intraoperative US and a utility score was devised(0 minimum, 7 maximum). Results: The utility score for intraoperative US was 7 in 3 cases(4%), 6 in 28 cases (54%), 5 in 21 cases (31%), 4 in 8 cases (11%), while no case had score ≤3. Conclusion: Intraoperative US is not only helpful in localizing lesions but also it can be usedin determining the morphology of the lesion for some cases, which was glioma in our case.Intraoperative US is also helpful when to start planning the site of entry and complete resection.

Introduction Patients presenting with a thyroid nodule, if malignant, may call for removal. A good screening tool with high diagnostic value for preoperative evaluation is preferred. Through real-time visualization of the needle to aspirate from the suspicious site, ultrasonography-guided fine-needle aspiration cytology could be an excellent screening tool. Materials and method A cross-sectional descriptive study was conducted at Ganesh Man Singh Memorial Academy of Ear Nose Throat–Head and Neck Studies, Kathmandu, Nepal, from September 2018 to November 2019. We included 59 subjects of 15–72 years meeting the inclusion criteria. All study participants underwent preoperative ultrasonography-guided fine-needle aspiration cytological evaluation of thyroid nodule, which was correlated with their histopathological findings to determine diagnostic values. Result The sensitivity, specificity, and accuracy of ultrasonography-guided fine-needle aspiration cytology of thyroid nodule was 96.96%, 61.53%, and 81.35%, respectively. On stratification according to size, high sensitivity of 100% was observed in evaluating lesions of size < 2 cm and > 4 cm. There was a good inter-rater agreement between findings of ultrasonography-guided fine-needle aspiration cytology and histopathology with a kappa coefficient of 0.607. Conclusion Ultrasonography-guided fine needle aspiration cytology is a reliable procedure to evaluate thyroid lesions with high diagnostic value. It is an excellent tool for evaluating small, non-palpable nodules.
