Breast radiologists are increasingly seeing patients with axillary adenopathy related to COVID-19 vaccination. Vaccination can cause levels I-III axillary as well as cervical lymphadenopathy. Appropriate management of vaccine-related adenopathy may vary depending on clinical context. In patients with current or past history of malignancy, vaccine-related adenopathy can be indistinguishable from nodal metastasis. This article presents imaging findings of oncology patients with adenopathy seen in the axilla or neck on cross-sectional imaging (breast MRI, CT, or PET-CT) after COVID-19 vaccination. Management approach and rationale is discussed, along with consideration on strategies to minimize false positives in vaccinated cancer patients. Time interval between vaccination and adenopathy seen on breast MRI, CT, or PET-CT is also reported.

목 적 : 초기 증상이 발열과 경부림프절종대인 Kawasaki병 환아와 경부 림프절염의 임상적 특징을 비교 관찰함으로써 Kawasaki병의 조기 진단과 치료에 도움을 주고자 하였다. 방 법 : 초기 진단이 임상적으로 경부 림프절염, 경부 농양, 비정형성 Kawasaki병 의증 등으로 치료받다 후에 임상적 진단 기준에 의해 Kawasaki병으로 최종 진단된 환아와 경부 림프절염 환아의 후향적 의무기록 조사를 하였다. 결 과 : 발열과 경부 림프절염이 주증상인 Kawasaki병은 일반적 Kawasaki병 보다 좀 더 나이든 환아에서 발생하였으며, 전신적 염증을 시사하는 소견이 더 높게 나타났다. 경부 림프절염 환아들과 비교하였을 시도 전신적 염증을 시사하는 소견이 의미있게 높았다. 경부 림프절염 환아는 항생제 치료 후 0~3.5일(평균 1.4일)내에 임상적 호전을 보였으나, Kawasaki병의 환아들은 항생제에 반응하지 않거나 다른 소견들이 나타나 입원 1~5일(평균 2.9일)에 감마 글로부린을 사용하였으며, 감마 글로부린 사용 후 평균 11.7시간 내에 발열이 소실되었다. Kawasaki병에서 심장에 나타나는 변화는 3례(20%)였으며, 림프절종대 유무와 관계가 없었다. 결 론 : 발열과 경부 림프절종대를 주소로 경부 림프절염 진단 하에 항생제 치료를 받는 환아 중 항생제에 반응하지 않는 경우, Kawasaki병의 검사실적 소견을 보일 때 다른 감염성 질환 외에 Kawasaki병을 꼭 고려해야 한다. Kawasaki병의 다른 임상적 소견들이 나타나는지 주의 깊게 관찰하여, 신속한 진단과 치료를 통해 심장 합병증을 방지하도록 해야 한다.

Ultrasonography is non-invasive and can give useful clues in the diagnosis of cervical lymphadenopathy, However, differential diagnosis is difficult in some situations even combined with color Doppler imaging. The present study was conducted to evaluate the clinical value of real time elastography in patients with unexplained cervical lymphadenopathy using a quantitative method. From May 2011 to February 2012, 39 enlarged lymph nodes from 39 patients with unexplained cervical lymphadenopathy were assessed. All the patients were examined by both B-mode ultrasound, color Doppler flow imaging and elastography. The method of analyzing elasto-graphic data was the calculation of the 10 parametres ("mean", "sd", "area%", "com", "kur", "ske", "con", "ent", "idm", "asm") offered by the software integrated into the Hitachi system. The findings were then correlated with the definitive tissue diagnosis obtained by lymph node dissection or biopsy. Final histology revealed 10 cases of metastatic lymph nodes, 11 cases of lymphoma, 12 cases of tuberculosis and 6 cases of nonspecific lymphadenitis. The significant distinguishing features for conventional ultrasound were the maximum short diameter (p=0.007) and absent of echogenic hilum (p=0.0293). The diagnostic accuracy was 43.6% (17/39 cases) and there were 17 patients with equivocal diagnosis. For elastography, "mean" (p=0.003), "area%" (p=0.009), "kurt" (p=0.0291), "skew" (p=0.014) and "cont" (p=0.012) demonstrated significant differences between groups. With 9 of the 17 patients with previous equivocal diagnoses (52.9%) definite and correct diagnoses could be obtained. The diagnostic accuracy for conventional ultrasound combined elastography was 69.2% (27/39 cases). There were differences in the diagnostic sensitivity of the two methods (p=0.0224). Ultrasound combined with elastography demonstrated higher rates of conclusive and accurate diagnoses in patients with unexplained cervical lymphadenopathy than conventional ultrasound. The quantitative program showed good correlation with the pathology of different lymph node diseases.

Background: Non-Hodgkin's lymphoma (NHL) is a heterogeneous type of neoplasm of the lymphatic system. To have a more accurate and early diagnosis we need to know signs, symptoms and complications of lymphoma in early stages besides pathology and immunohistochemistry. Materials and Methods: This prospective study included 110 cases of NHL that were followed since February 2012 till November 2013. Biopsies were taken from all the patients besides bone marrow study. Signs and symptoms were categorized into "B" symptoms, general, lymphadenopathy and extranodal involvement and we compared the frequencies by stage and grade. Results: Of 110 cases, 88.9% had B-cell and 11.1% T-cell type with mean age $48.5{\pm}18.6$ years. "B" symptoms and lymphadenopathy were more common in men. Cervical lymphadenopathy was the most common sign (44.8%). and hematologic, bone marrow, bone and neurologic lesions were the most common complications. All complications were more common in males. "B" symptoms were seen mostly in stage III, general signs and symptoms in stage IV, and lymphadenopathy in stage II. Intermediate grade was also the most common in all signs and symptoms. In this study 12 (10.9%) patients had relapse, with neurologic and bone marrow as the most common sites of tumor recurrence. Conclusions: There is a meaningful relationship between male gender for NHL and anemia that can be due in part to higher incidence of bone marrow involvement and stage IV disease in male cases. We also found a strong relationship between low grade NHL and age. On the other hand extranodal involvement is more common in female groups.

Clinical analysis was performed on 306 patients with cervical lymphadenopathy who were diagnosed histologically by fine needle aspiration biopsy cytology (FNABC) and/or excisional biopsy from Jan 1986 to Jan 1990 at Hanyang University hospital. The results obtained were as follows: 1) Of 306 patients with cervical lymphadenopathy, 216 (70.6%) were inflammatory lesions, and 90 (29.4%) malignant lesions. Tuberculous lymphadenitis of inflammatory lesions was most common (134 cass: 62%). Of malignant lesions, metastatic cancer was more frequent (75 cases: 83.3%). 2) The sex ratio were as follows: inflammatory lesion; M:F=1 : 1.8 (tuberculous lymphadenitis;M : F=1:2.3) malignant lesion; M : F=1.5 : 1 (metastatic cancer; M : F=2.6 : 1) 3) The peak age of inflammatory lymphadenopathy was 20-29 years old (38.9%), and that of malignant lesion 50-59 years old (46.7%). 4) In more than half of tuberculous lymphadenitis and metastatic cancer, the location of enlarged lymph nodes was one side of the neck and the number was more than one. 5) The common primary sites of metastatic cancer were lung and stomach. In 11 cases (14.7%), the primary site could not be found. 6) The sensitivity and the specificity of fine needle aspiration biopsy cytology (FNABC) was 0.83 & 1.0 in metastatic cancer respectively.

Progressive transformation of germinal centers (이하 PTGC)는 드물게 나타나는 양성 림프절 질환으로, 주로 만성적인 림프절 비대의 형태로 나타난다. 주로 한 개 또는 여러 개의 림프절의 무통성 비대로 나타나며, 가장 흔히 침범하는 부위는 경부 림프절, 다음으로 액와부와 서혜부 림프절로 알려져 있다. 일부 환자들에서는 조직병리에서 림프종이 함께 존재하기도 하지만, PTGC 자체는 전암병변으로 인식되지는 않는다. 조직학적으로 PTGC로 진단되는 경우도 적지만, 이에 대한 영상의학적 소견은 거의 보고된 바가 없다. 이에 저자들은 침윤성 유방암 환자에서 수술 후 반대편 액와부 림프절 비대로 나타나 전이성 림프절로 오인한 PTGC 증례의 영상 소견을 보고하고자 한다.

Chronic lymphocytic leukemia (CLL)is the most common leukemia in adults in Western countries but is relatively rare in Asia. Immune hemolytic anemia, Evan's syndrome, lymphadenopathy, organomegaly and B symptoms are the main complaints of patients in CLL. The present retrospective analysis evaluated a group of 109 patients with CLL over a 9-year period, studying correlations between sex, age and overall survival. The patients were hospitalized in the Clinic of Hematology and Oncology, Kermanshah, Iran, between 2006 and 2014. Data analysis for sex and age was performed using IBM SPSS19 and overall survival was plotted by Kaplan-Meier plot, Log-rank test in Graph Pad prism 5 Software for five-year periods. The mean age of diagnosis for CLL patients was 60.73 years, 59.6% male. Survival rate patients was 64% and mean overall survival was 38.5 months. In the Rai system, fourteen patients (12.8%) had stage III and twenty eight patients (25.7%) had stage IV. Most frequent clinical features in patients with CLL were lymphadenopathy (38.7%) and organomegaly (34%), respectively. There is not relationship between sex and age in patients but overall survival rate in females was higher than in males. In Asian countries, CLL is more in male and in age above 60 years. Complaints about lymphadenopathy and virus infection are prevalent.
