“…The results are consistent with Pattanayak et al [34,36] that weakness of the presents cases and coagulation necrosis is uncommon in lymphomatous CLN. Xiaoyin et al [37] mentioned that coagulation necrosis (infraction) takes place due to rapidly growing neoplasm and observed a few cases with coagulation necrosis especially in diffuse Large B-Cell Lymphoma (DLBCL).…”

“…Among benign causes, macrocalcifications most often result from prior granulomatous infections, especially tuberculosis and histoplasmosis. Other, less common causes include sarcoidosis, silicosis, and amyloidosis [ 28 29 ]. Although the prevalence of a large EF was low in this study and showed no significant association with that of metastatic LNs in patients with thyroid cancer, the malignancy rate was as high as 82.6%.…”

Objective To evaluate the ultrasonography (US) features for diagnosing metastasis in cervical lymph nodes (LNs) in patients with thyroid cancer and compare the US classification of risk of LN metastasis between European and Korean guidelines. Materials and Methods From January 2014 to December 2018, US-guided fine-needle aspiration was performed on 836 LNs from 714 patients for the preoperative nodal staging of thyroid cancer. The US features of LNs were retrospectively reviewed for the following features: size, presence of hilum, margin, orientation, cystic change, punctate echogenic foci (PEF), large echogenic foci, eccentric cortical thickening, abnormal vascularity, and cortical hyperechogenicity. A multiple logistic regression analysis was performed to identify the independent US features for the diagnosis of metastatic LNs. The diagnostic performance of independent US features was subsequently evaluated. LNs were categorized according to the Korean Thyroid Imaging Reporting and Data System (K-TIRADS) and European Thyroid Association (ETA) guidelines, and the correlation between the two sets of classifications was assessed. Results Absence of the hilum, presence of cystic changes, PEF, abnormal vascularity, and cortical hyperechogenicity were independent US features of metastatic LNs. Cystic changes, PEF, abnormal vascularity, and cortical hyperechogenicity showed high specificity (86.8%–99.6%). The absence of the hilum had the highest sensitivity yet low specificity (66.4%). When LNs were classified according to the ETA guidelines and K-TIRADS, they yielded similar categorizations of malignancy risks and were strongly correlated (Spearman coefficient, 0.9766 [95% confidence interval, 0.973–0.979]). According to the ETA guidelines, 9.8% (82/836) of LNs were classified as “not specified.” Conclusion Absence of hilum, cystic changes, PEF, abnormal vascularity, and cortical hyperechogenicity were independent US features suggestive of metastatic LNs in thyroid cancer. Both K-TIRADS and the ETA guidelines provided similar risk stratification for metastatic LNs with a high correlation; however, the ETA guidelines failed to classify 9.8% of LNs into a specific risk stratum. These results may provide a basis for revising LN classification in future guidelines.

“…We also investigated the pattern and extent of lymph node calcification because such characteristics of lymph node calcification could made disease more specific. Considering the fact that BAF can arise from exposure of biomass fuels and occupational dust, we anticipated that calcification pattern of BAF could be similar to lymph node pattern of TB or occupational lung disease such as silicosis 7 , 21 , 22 . However, eggshell calcification, a classic pattern of occupational lung disease, was not detected in this study.…”

Background: There are many similarities between lung cancer and anthracofibrosis (AF), both are common and present with similar symptoms and radiological findings. This study aimed to describe the clinical radiological differentiation between AF and endobronchial lung cancer, both confirmed by bronchoscopy.Methods: This is a retrospective study of patients with AF or bronchoscopic biopsy confirmed endobronchial lung cancer from 2008 to 2014. The reviewed data were derived from a bronchoscopy registry made on January 1, 2008. We analyzed the clinical and radiological characteristics of both diseases.Results: Among the 3214 patients who underwent bronchoscopy, 167 and 117 patients were enrolled in the AF and lung cancer groups, respectively. AF occurred more predominantly in older non-smoking female patients with a higher chance of tuberculosis (38.3%) than in those with lung cancer (6.0%). Common symptoms reported were cough, sputum, and dyspnea in both groups. Bronchoscopic findings revealed that AF lesions were more common in the multiple lobar bronchi (85.0%) or bilaterally (73.7%). Radiologic findings revealed that bronchial stenosis was the most commonly found lesion in both groups (49.1% vs. 78.6%).Rates of peribronchial calcification and bronchial wall thickening were high in the AF group.The number of patients with lymph node enlargement and calcification was also higher in the AF group. Conclusion:Our study demonstrated the characteristic of clinical radiologic findings in AF and endobronchial lung cancer. Increasing the awareness of both diseases may help clinicians to differentiate the diseases from each other, avoiding unnecessary invasive diagnostic procedures.
