The human HOXA1 mutation syndromes commonly present with abnormalities of the inner ear and ICAs. Previous cases describe varying degrees of hypoplasia or aplasia of the affected structures, often with asymmetric involvement. We present imaging findings documenting complete absence of the ICAs bilaterally with bilateral CLA, which, to our knowledge, has not been previously reported.
人类 HOXA1 突变综合征常伴有内耳和颈内动脉(ICA)异常。既往病例描述了受累结构的不同程度的发育不良或发育不全,常伴有不对称受累。我们呈现的影像学发现记录了双侧 ICA 完全缺失伴双侧 CLA,据我们所知,这在以前的报道中尚未出现过。
