Francisella tularensis, the causative organism in Tularemia, is a relatively rare disease. There are a few radiological clues to elucidate its presence when suspicion arises. There should be strong consideration for Tularemia in the differential of any patient with its classic symptoms, diffuse cervical lymphadenopathy with evidence of necrosis, and enlarged adenoids. Ultrasound may demonstrate suppurative lymphadenopathy suggestive of infection, as in the case presented. CT often will demonstrate the extent of lymphadenopathy. On chest radiography, tularemia pneumonia is often the presenting finding, which may demonstrate bilateral or lobar infiltrates. Additionally, hilar lymphadenopathy and pleural effusions are often associated findings. Cavitary lesions may be present, which are better delineated on CT scan. We present a case of a 7-year-old male who presented with a painful right-sided palpable neck mass for 9 days, who was diagnosed with Tularemia after numerous admissions.
土拉弗朗西斯菌是兔热病的病原体,兔热病是一种相对罕见的疾病。当怀疑有兔热病时,有一些影像学线索可用于明确其存在。对于任何有典型症状、伴有坏死证据的弥漫性颈部淋巴结病和腺样体肿大的患者,在鉴别诊断时都应高度考虑兔热病。超声可能显示提示感染的化脓性淋巴结病,如本病例所示。CT通常能显示淋巴结病的范围。胸部X线检查时,兔热病肺炎常为首发表现,可显示双侧或大叶性浸润。此外,肺门淋巴结肿大和胸腔积液常为相关表现。可能存在空洞性病变,CT扫描能更好地显示这些病变。我们报告一例7岁男性,因右侧颈部可触及疼痛性肿块9天就诊,经多次入院后被诊断为兔热病。
