Case 5: A 38-year-old female, with family history for breast cancer, was evaluated for left breast and left axillary pain with baseline diagnostic mammogram and ultrasound. The involved lymph nodes in all three cases typically drain the arm . These events included lymphadenopathy, lymphadenitis, lymph node pain, vaccination-site lymphadenopathy, injection-site lymphadenopathy, and axillary mass, which were plausibly related to vaccination. I expected to find bilateral parotid swellings from the mumps component, but to my surprise she had bilateral enlarged post auricular and suboccipital lymph glands. As directed by an ongoing clinical trial, the patient started treatment with vemurafenib, cobimetinib and atezolizumab. However, this review is based on only five studies, all of which were assessed as having a low or very low quality of evidence. The median duration of lymphadenopathy was 1 to 2 days. vaccination, thought to have occurred after BCG vaccination (Bellet et al., 2005). Stereotactic biopsy of the left breast asymmetry revealed fibrocystic change with pseudoangiomatous stromal hyperplasia, concordant with radiology findings. B, Ultrasound evaluation of the left axilla demonstrates a lymph node with abnormally thickened cortex (yellow arrow). %PDF-1.6 %���� Coronavirus: ... demonstrating new left axillary adenopathy measuring up to 1.4 cm in short axis 8 days after an mRNA COVID-19 vaccination. Ipsilateral axillary lymphadenopathy following vaccinations has been previously reported with vaccinations other than COVID-19. In the above vaccine trials, abnormal lymphadenopathy was reported based on physical examination rather than using imaging. Vaccination is recommended at least 2-4 weeks prior to the planned immunosuppressive therapy, transplant or splenectomy.

Mootz MD, UT Southwestern Medical Center, Department of Radiology . dermato@hsmbraga.min-saude.pt We report a 15-month-old boy who developed an ulcer in … These images highlight that FDG-uptake might resolve within a few weeks, while lymph node enlargement could persist beyond five-weeks after injection ( 3 ). A, Bilateral MLO views demonstrate an asymmetry (yellow arrow) in the left superior breast which was biopsied as pseudoangiomatous stromal hyperplasia. Reports of lymphadenopathy were imbalanced with 58 more cases in the vaccine group (64) than the placebo group (6); lymphadenopathy is plausibly related to the vaccine. F, On ultrasonography, axillary lymph nodes had thickened cortex while the supraclavicular lymph node demonstrated, G, thickened cortex with loss of normal fatty hilum. In two cases, we had pathologic confirmation of benign reactive lymphadenopathy secondary to vaccination and to our knowledge, these are the first pathologically proven cases in the literature. If your hospital, university, trust or other institution provides access to BMJ Best Practice through services such as OpenAthens or Shibboleth, log in via this button: Therefore, radiologist/clinicians should question recent history of COVID-19 vaccination in cases of unilateral axillary lymphadenopathy. Three-month follow-up 18-FDG PET/CT (per the clinical trial protocol) showed complete resolution of the known hypermetabolic metastatic intraparotid lymphadenopathy. Further evaluation with PET/CT six days after the 2nd dose of vaccine, demonstrated, C, multiple enlarged hypermetabolic left axillary lymph nodes and, D, a hypermetabolic round shaped left supraclavicular lymph node in axial fused 18-FDG PET/CT images. endstream endobj startxref As a consequence, the authors conclude there is an urgent need for more and better studies on ways to prevent and treat BCG-induced disease, especially … The first two FDA-approved coronavirus disease (COVID-19) vaccines are highly immunogenic, with reports of ipsilateral axillary lymphadenopathy and FDG-uptake post-vaccination (1,2). SE, MMC 292, Minneapolis, MN 55455, USA (C.O., L.A.K., A.L.C., A.C., J.M.E., D.S. However, patient opted for ultrasound guided core needle biopsy of axillary and supraclavicular lymph nodes, which occurred 35 days after the first and 16 days after the second dose of COVID-19 vaccine. On histopathologic exam, both nodes were consistent with benign reactive lymph nodes, without any evidence of breast cancer metastasis (Figure 4I, 4J, 4K). Muscle Pain 10. None of these were confirmed as reactive lymphadenopathy on histopathology; but based on clinical and radiological findings, follow-up was recommended. The federal government has a contract with Pfizer-BioNTech for 100 million doses … Axillary Lymphadenopathy After mRNA COVID-19 Vaccination . Bell’s palsy was reported by three vaccine recipients and one placebo recipient. Figure 5: 38-year-old presented for evaluation of left breast and left axillary pain. The patient started additional metastasis-directed stereotactic radiotherapy and subsequent follow-up imaging surveillance with whole body MRI. Cecelia C. Brewington MD, UT Southwestern Medical Center, Department of Radiology A routine follow-up chest CT showed new mild left axillary and left supraclavicular lymphadenopathy (Figure 4B). Case 1: A 32-year-old female presented with a left sided neck mass. Lymphadenopathy after BCG vaccination in a child with chronic granulomatous disease. Radiologically, hypermetabolism in the ipsilateral lymph nodes was reported with 18-FDG PET/CT exams following seasonal H1N1 Influenza-A vaccines (7-9). One case of Bell’s palsy in the vaccine group was considered a serious adverse event. Mild symptoms after the first dose are not a contraindication to a second dose vaccination, which is necessary for better protection against the virus. Therefore, 18-FDG PET/CT was performed for further evaluation. However, PET/CT revealed multiple new, mildly enlarged, and hypermetabolic left axillary lymph nodes with fat stranding. B, Surveillance contrast enhanced axial chest CT showed new left axillary lymphadenopathy with fat stranding 15 days after the first Covid-19 vaccine. A description of these patients is below. Although influenza vaccination is a potential source of false positive results in FDG PET studies, generalised lymph node activation post vaccination is a rare finding with only one prior published report in individuals infected with HIV-1. V-safe asks questions that help CDC monitor the safety of COVID-19 vaccines. If experienced, these tend to have a Less Severe expression 1. We would like to thank Dr Bruce C. Trautman for his help with the histopathologic evaluation, and Dr Katherine Chang for informing us about one of the cases. Cases were identified from our institution from 12.21.2020 to 1.27.2021.

However, further investigation revealed that the patient received the second dose of Pfizer-BioNTech COVID-19 vaccine six days prior to PET/CT and there was triangular intramuscular FDG uptake in the left arm at the injection site (Figure 1). Presumably this is … To our knowledge, a single PET/CT case was published similar to our fourth patient, although this case was without pathologic confirmation (12). Knowledge of the potential for COVID-19 vaccine-related ipsilateral adenopathy is necessary to avoid unnecessary biopsy and change in therapy. The patient was recalled for left axillary ultrasound. In the Moderna cohort, clinically detected axillary and supraclavicular lymphadenopathy was reported in 1.1% of study participants within 2-4 days after vaccination, as an unsolicited adverse event (4). In addition, in this limited series, a triangle of intramuscular inflammation was demonstrated at the injection site on MRI and PET/CT, as also described by Eifer and Eshet (12), suggesting vaccine-related inflammation. Ultrasound guided core needle biopsy of the left axillary lymph node revealed reactive follicular hyperplasia without any evidence of malignancy. However, further investigation revealed that patients received COVID-19 vaccinations in the ipsilateral arm prior to imaging. With any vaccination, you can expect a bit of pain during and after the injection, says Dr. Thomas Duszynski, director of epidemiology education at … Signs of a severe allergic reaction can include: Difficulty breathing Vieira AP(1), Vasconcelos J, Fernandes JC, Antunes H, Basto AS, Macedo C, Zaman A, Santos E, Melo JC, Roos D.
