We report a case of a 41-year-old male who presented to our institution with a large groin mass. CT, MRI and PET imaging was performed and was concerning for a soft tissue abscess likely originating in the lumbar spine. Differential considerations included infection, with atypical infections such as tuberculosis strongly considered. Biopsy revealed fungal elements preliminarily reported as consistent with Cryptococcus neoformans but later revealed to be Blastomyces dermatitidis. The patient responded positively following the introduction of appropriate treatment. This case illustrates the imaging similarities between spinal blastomycosis, spinal tuberculosis, and other fungal infections as well as the need for biopsy to differentiate.
我们报告了一例 41 岁男性患者，因巨大腹股沟肿块就诊于我院。进行了 CT、MRI 和 PET 成像，提示可能源于腰椎的软组织脓肿。鉴别诊断包括感染，尤其是结核等非典型感染。活检显示真菌成分，初步报告为新型隐球菌一致，但后来发现为皮炎芽生菌。引入适当的治疗后，患者反应良好。本病例说明了脊柱芽生菌病、脊柱结核和其他真菌感染之间的影像学相似性，以及鉴别诊断需要进行活检。
