The hibernoma is a rare benign tumor of soft tissue, derived from remnants of fetal brown adipose tissue. A cervical rib is a supernumerary or accessory rib derived from the 7th cervical vertebra. CLINCAL CASE: 2-year-old girl, previously healthy, referenced to Pediatrics consultation, for left supraclavicular mass. No history of infectious diseases or systemic symptoms. At exam presented mass in supraclavicular left region, 1.5 to 2 cm in diameter, hard, mobile, non-adherent to the deep planes. Laboratory tests exclude an infectious or lymphoproliferative disease. In cervical radiograph we observed bilateral cervical ribs. Cervical ultrasound revealed calcified nodule 0.8 cm, compatible with calcified adenopathy. Biopsy was performed and histology revealed a hibernoma, which was completely removed surgically. This case illustrates the association of two diagnoses, uncommon in children. These were made during the investigation of lymphadenopathies, a frequent reason for pediatrics consultation.
冬眠瘤是一种罕见的软组织良性肿瘤，起源于胎儿棕色脂肪组织的残余。颈肋是源自第7颈椎的多余或副肋。临床病例：一名2岁女童，既往健康，因左锁骨上肿块转诊至儿科会诊。无传染病史或全身症状。检查发现左锁骨上区有肿块，直径1.5至2厘米，质地硬，可活动，不与深部平面粘连。实验室检查排除感染性或淋巴增殖性疾病。颈椎X光片显示双侧颈肋。颈部超声显示一个0.8厘米的钙化结节，符合钙化性淋巴结病。进行了活检，组织学检查显示为冬眠瘤，已通过手术完全切除。本病例说明了两种诊断的关联，这在儿童中并不常见。这些诊断是在对淋巴结病进行调查期间做出的，而淋巴结病是儿科会诊的常见原因。
