Background: Aims and Objectives - 1) to do a comparative evaluation of ultrasonography and computed tomography in pancreatic lesions and assess their role as a useful diagnostic tool. 2) To correlate the USG and CT findings with fine needle aspiration cytology (FNAC)/ histopathological findings/ laboratory tests / therapeutic follow up wherever performed,Material and Methods: The present study was carried out in the Department of Radio-diagnosis, Maharishi Markandeshwar Institute of Medical Sciences and Research, Mullana, Ambala. Thirty patients presenting with signs and symptoms of suspected pancreatic lesions referred from various wards and outpatient departments were included in the study.Results: On USG, inflammatory lesions were diagnosed in 15 cases (50%), and on CT scan, the diagnosis was made in 18 patients (60%). Combining the USG & CT findings of inflammatory lesions, the provisional radiological diagnosis of focal pancreatitis was made in 1 case but it was proven to be adenocarcinoma on FNAC. Provisional diagnosis of adenocarcinoma was made in 8 cases, lymphoma in 2 cases, macrocystic adenoma in 1 case and cystadenocarcinoma in 1 case on both USG and CT scan. However on FNAC, adenocarcinoma was proved in 10 patients, lymphoma was found in one case. Thus the provisional radiological diagnosis was correct in 28 patients (93.7%).Conclusion: Sonography detected pancreatic pathology in 27 cases (90%) but CT scan detected pancreatic lesions in all the 30 patients (100%). Present study had been undertaken to do a comparative evaluation of ultrasonography and computed tomography in pancreatic lesions and correlated the findings with fine needle aspiration cytology (FNAC) / HPE / laboratory tests / therapeutic follow up wherever performed. A need thus exists for multiple studies to produce significant in – road towards the appropriate imaging diagnosis of pancreatic pathologies as despite the rapid advances in imaging techniques, the overall impact of these modalities on the management and outcome of patients is still debatableJ MEDICINE July 2016; 17 (2) : 66-78

AbstractAspirates were obtained from 142 masses in 120 patients who presented with palpable swellings in the head and neck region. 120 specimens (84.51 per cent) were adequate for diagnostic purposes and the remaining 22 (15.49 per cent) were unsatisfactory. Final diagnosis was based on resection histology in 87 cases and close clinical follow-up in 55 patients. The overall sensitivity and specificity including unsatisfactory aspirates was 81.37 per cent and 93 per cent respectively (if the technically inadequate specimens were deleted 98.81 per cent and 94.44 per cent). In comparison with the final diagnosis typing of malignant tumours was possible in 58.33 per cent. The correct diagnosis was made in 63.89 per cent of benign lesions.

Needle Aspiration Cytology

The therapeutic and prognostic evaluation of malignant neoplasias depends largely upon a precise morphologic diagnosis. Several papers have focused on the importance of fine-needle aspiration under computed tomography guidance in the diagnosis of unresectable neoplasms and in the investigation of metastases. The objective of this study is to evaluate the diagnostic accuracy, the sensitivity, and the negative predictive value obtained with the technique. Fine-needle aspiration cytology (FNAC) was performed on 207 patients, with a total of 210 cases, from 1991 to 1994, under computed tomography (CT) guidance. There were 128 (61.8 percent) males and 79 (38.2 percent) females with a mean age of 41 years (range 1 to 91 years). Lung and liver were the most frequent anatomic sites. The analysis of this material disclosed 41 cases with cytological diagnosis of negative for malignancy (19.52 percent), and in 131 (62.38 percent), the diagnosis was positive. It was possible to define the cytologic lineage in 54 percent of the cases. The diagnosis in 14 (6.67 percent) cases was suspicíous for malignancy, and in 24 (11.43 percent) cases the material was insufficient for the cytologic diagnosis. Of the 210 cases, 106 showed histological diagnosis and/ or clinical follow-up. Forty-seven (44.3 percent) had histological diagnosis before the FNAC and 50 cases (56.7 percent) histological diagnosis after the procedure. The comparison between cytological and histological diagnosis showed a sensibility of 80.4 percent, specificity of 100 percent, positive predictive value of 100 percent and negative of 16.7 percent. The efficiency of the test was 81.1 percent. This study showed that FNAC, under computed tomography guidance, is a sensitive and specific technique for the diagnosis of deep-seated lesions.

Needle Aspiration Cytology

A 45-year-old woman presented with a neck swelling since the past 6 years. The swelling was painless but slowly and progressively increasing in size. On examination, a thyroid swelling of size approximately 6×4 cm was seen on the left side. Ultrasonography revealed the size to be 6×5 cm with microcalcifications. Fine needle aspiration cytology revealed the mass to be papillary carcinoma. She was planned for total thyroidectomy with central compartment clearance. Preoperative assessment including thyroid hormone profile was normal and the patient was taken for surgery after proper anaesthesia clearance. During the surgery, it was found that there was a branching of the left recurrent laryngeal nerve. The branching was confirmed with nerve monitor and careful dissection was done to prevent injuries. The surgery was completed successfully without any nerve damage and the postoperative period was uneventful. Follow-up assessments revealed no signs of nerve injury like hoarseness of voice. Possibility of abnormal branches and duplication of nerves though uncommon should not be underestimated and extra vigilance and caution must be exercised when operating near a nerve, even by an experienced surgeon familiar with the local anatomy. Any doubts arising during the surgery must be clarified immediately, and nerve monitors should be used to check suspected branching and duplications before proceeding further.
