METHODS: A 14 year old Caucasian male with background of autism and severe dietary restriction presented with lower limb swelling and immobility. He was diagnosed with lower limb DVT. Further investigation revealed an iron deficiency anaemia, and he was found on MRI to have large bilateral subperiosteal iliac hematomata causing compression of the iliac vessels. He improved following treatment with vitamin C replacement and follow-up imaging demonstrated resolution of the DVT and hematoma.
CONCLUSIONS: DVT is rare in children and when diagnosed should prompt investigation as to the underlying cause. This case demonstrates an unusual cause of DVT and as an unusual presentation of paediatric scurvy.
方法:一名14岁白人男性,患有自闭症和严重的饮食限制,表现为下肢肿胀和不活动。他被诊断为下肢DVT。进一步调查显示缺铁性贫血,MRI发现双侧骨膜下髂骨大血肿导致髂血管受压。他在接受维生素C替代治疗后有所改善,随访影像学显示DVT和血肿的分辨率。
结论:DVT在儿童中很少见,诊断时应及时调查其根本原因。此病例显示了DVT的异常原因,并且是儿科镰刀病的异常表现。
