Background: Fine needle aspiration cytology and core needle biopsy are reliable procedures for breast cancer detection. Core needle biopsy is an established alternative to surgical biopsy for diagnosis and prognostication. However, there may be a concern that core needle biopsy may be less reliable than excisional biopsy. The aim of this study was to compare the cytological/core needle biopsy finding with excisional histopathological diagnosis and determine their hormonal status. Materials and Methods: A prospective study of 65 patients was conducted after obtaining a detailed clinical data. The comparison of the fine needle aspiration cytology/core needle biopsy finding with excisional histopathological diagnosis of breast malignancy was carried out after data analysis. Their ER, PR and HER-2/neu status was also studied in available cases. Results: Out of the 65 cases of breast malignancy, 69.2% of cases had undergone fine needle aspiration, 60% cases core needle biopsy and 93.8% cases excisional biopsy. The most common carcinoma was invasive carcinoma of no special type. The diagnostic accuracy of fine needle aspiration and core needle biopsy was almost equal, however, core needle biopsy could assess the histological typing and biomarker status. The hormonal status was assessed in 69.23% cases, among them 35.6% cases were triple negative carcinomas. Conclusions: Core needle biopsy was superior to fine needle aspiration cytology in the diagnosis of breast lesions in terms of diagnostic accuracy. Thus, our result provides valuable prognostic information to guide the decision-making process for the treatment of a patient with invasive carcinoma.
Introduction: Cervical region is the commonest area of lymphadenopathy which is easily accessible to ultrasound and Doppler study. The morphological and vascular-architectural differences among various nodal diseases aids in differentiating benign from malignant causes. Methods: The study was done on the 108 patients referred to Department of Radiology andImaging, TUTH for ultrasound of cervical lymphadenopathy who subsequently underwentFNAC examination. Gray scale evaluation for morphology of the nodes along with Doppler evaluation for resistive index (RI), pulsatility index (PI) and Peak systolic velocity (PSV) were done and correlated with FNAC findings. Results: Among the 108 lymph nodes, 24 were proven to be malignant on FNAC. Features such as S/L ratio >0.5, absence of echogenic hilum, and abnormal vascular pattern demonstrated sensitivities of 96%, 92%, and 87%, specificities of 74%, 65% and 77% and positive predictive values (PPVs) of 51%, 43%, and 55% respectively. The cutoff values for RI, PI and PSV were found to be 0.705, 1.34 and 17.5 cm/s with sensitivities of 96%, 96% and 87%, specificities of 95%, 99% and 88% and positive predictive values (PPVs) of 85%, 95% and 70% respectively. Conclusion: Ultrasound findings of S/L ratio, absence of echogenic hilum, abnormal vascular pattern and Doppler indices revealed good sensitivity, specificity, and accuracy in differentiating benign and malignant lymph nodes.
Castleman disease (CD) is a group of lymphoproliferative disorders with common lymph node histological features. It may be either unicentric or multicentric. Unicentric Castleman disease (UCD) is localized and carries an excellent prognosis, whereas multicentric Castleman disease (MCD) is a systemic disease occurring most commonly in the setting of HIV infection and is associated with human herpesvirus 8.1Castleman disease in the abdomen and pelvis is rare and liable to misdiagnosis, but its characteristic imaging features can help in the diagnosis and differential diagnosis.2Unicentric Castleman disease (UCD) is rare, and there are no reliable estimates of its incidence in the population. While UCD can occur at any age, it is generally a disease of younger adults. The median age at presentation is approximately 35 years.3, 4
Background Coronavirus disease (COVID-19) is the recent global health emergency making it crucial for rapid diagnosis and intervention. Computed tomography (CT) is important for screening, diagnosis and evaluating severity and disease progress. Objective To assess the CT changes in COVID patients and study its relationship with various factors. Method A retrospective study was conducted at Norvic International hospital from August 2020 to November 2020 among RT-PCR positive symptomatic COVID cases who had positive CT changes. CT imaging data were analyzed by radiology expertise. Statistical analysis was carried out with the help of SPSS 16. Result Out of 120 patients, 75% were males and mean age was 54.70±15.56 years. The mean CT severity score was 18.35±6.87. Pure ground glass opacities was seen in 74(61.7%), reticulations 89(74.2%) and crazy-paving pattern 28(23.3%). CT scans with bilateral 118(98.3%) and peripheral involvement 109(90.8%) in all five lobes. CT- severity score was positively correlated with oxygen and mechanical ventilation requirement (P-value < 0.05 and 0.011 respectively). Conclusion CT findings including pure ground glass opacities, reticulations, bilateral and peripheral involvement involving all five lobes were more frequent. Our data suggest that CT-severity score significantly correlates with oxygen and mechanical ventilation requirements.
Background Ultrasound (USG) with Doppler examination of intrarenal vessels is the imaging modality of choice employed in patients with renal failure and is commonly performed early in the clinical course. The pulsatility index (PI) and the resistive index (RI) of downstream renal artery have been found to correlate with renal vascular resistance, filtration fraction and effective renal plasma flow in chronic renal failure. Pathological process in any tissues alters their elastic properties which can be assessed non-invasively through newer technique like elastography. Objective To correlate the findings obtained by sonoelastographic, doppler and histopathological studies in chronic kidney disease patients. Method Study was done in 146 patients referred to Department of Radiodiagnosis and Imaging, TUTH for native renal biopsy. Renal sonographic morphology (length, echogenicity, cortical thickness), Sonoelastography (Young’s modulus) and Doppler parameters (peak systolic velocity, resistive index) were assessed. The grading of estimated GFR (eGFR) was calculated based on chronic kidney disease (CKD) criteria. Result Among 146 patients, 63 (43.2%) were females and 83 (56.8%) were males. Maximum patients were in age group of 41-50 years (25.3%) followed by age group 51-60 years (24%). Mean age of patient was 42.06±14.70 for males and 39.57±12.54 females. Maximum mean Young’s modulus was seen in eGFR stage G1 with 46.57±19.51 kPa followed by in stage G3a with 36.46±10.01 kPa and observed to be statistically non-significant (p=0.172). However, statistical significance difference was noted between the resistive index and elastographic measurement of Young’s modulus (r=0.462, p=0.0001). Minimum mean cortical thickness was seen in eGFR stage G5 with 4.42±1.48 mm followed by stage G4 with 5.57±1.24 mm (p= 0.0001). Cortical thickness is decreasing as eGFR stage was increasing in our study (p=0.0001). Resistive index is increasing with decrease in renal size (r=-0.202, p=0.015). Conclusion Ultrasonography along with doppler study and elastography have limited role in diagnosing the pathology of chronic kidney disease, however, it has significant role in the disease progression.
