Hypersensitivity reactions to the COVID-19 mRNA vaccines were identified in the initial 2020 trials. Appearance of a soft tissue mass is a rare manifestation of this hypersensitivity reaction. In this patient, bilateral injections resulted in the appearance of shoulder masses. Magnetic resonance imaging showed localized pseudo-tumorous edema in both shoulders, one subcutaneous and the other intramuscular. This is only the second case of a mass-like reaction to the COVID-19 vaccine mimicking a possible soft tissue neoplasm. Improper vaccination administration technique may have contributed to this complication. The case is presented to increase awareness of this potential pseudotumor.
在2020年最初的试验中发现了对新冠mRNA疫苗的超敏反应。软组织肿块的出现是这种超敏反应的罕见表现。在该患者中，双侧注射导致肩部出现肿块。磁共振成像显示双侧肩部均有局限性假肿瘤样水肿，一处位于皮下，另一处位于肌肉内。这是第二例类似肿块的新冠疫苗反应，疑似软组织肿瘤。不当的疫苗接种管理技术可能导致了这一并发症。现将该病例呈现出来，以提高对这种潜在假肿瘤的认识。
