Deficiency of adenosine deaminase 2 (DADA2) is a rare, recessively inherited autoinflammatory disease with a wide clinical spectrum of manifestations, including strokes and vasculitis.
We report a case of a patient with DADA2 who presented with neurologic manifestations.
A 42-year-old woman with a known diagnosis of polyarteritis nodosa experienced several episodes of TIAs. Neuroimaging revealed 2 aneurysms in unusual locations. Her young age, ethnic origin, absent of cardiovascular risk factors, and skin involvement raised the suspicion of DADA2. Genetic testing confirmed the diagnosis, and a directed treatment with anti-TNF was initiated.
DADA2, although thought to be rare, needs to be borne in mind when evaluating patients with a combination of neurologic and systemic symptoms, as early diagnosis and treatment are imperative in preventing permanent disability.
腺苷脱氨酶2（DADA2）缺乏症是一种罕见的常染色体隐性遗传性自身炎症性疾病，临床表现谱广泛，包括中风和血管炎。
我们报告1例表现为神经系统症状的DADA2患者。
一名已知诊断为结节性多动脉炎的42岁女性经历了数次短暂性脑缺血发作。神经影像学检查发现2个位于不寻常位置的动脉瘤。她年轻、特定种族出身、无心血管危险因素以及皮肤受累情况引发了对DADA2的怀疑。基因检测确诊了该疾病，并开始了抗TNF定向治疗。
DADA2虽然被认为罕见，但在评估伴有神经系统和全身症状的患者时需要考虑到，因为早期诊断和治疗对于预防永久性残疾至关重要。
