Cerebral cavernous malformations (CMs) are typically not seen during conventional digital subtraction angiography (DSA) and are therefore classically referred to as angiographically occult malformations. We present three cases in which DSA with selective intra-arterial contrast injection in the common carotid artery and C-arm cone beam CT imaging was able to demonstrate a CM. In addition, an associated developmental venous anomaly (DVA) was present in all three cases, although detected by MRI in only one of them. In light of this finding, we suspect that the incidence of DVA associated with CM is probably higher than previously reported.
脑海绵状血管畸形(CMs)在传统数字减影血管造影(DSA)中通常不可见,因此传统上被称为血管造影隐匿性畸形。我们报告了3例病例,其中通过在颈总动脉进行选择性动脉内造影剂注射的DSA和C形臂锥形束CT成像能够显示出CM。此外,所有3例病例均存在相关的发育性静脉异常(DVA),尽管仅在其中1例中通过MRI检测到。鉴于这一发现,我们怀疑与CM相关的DVA的发生率可能高于先前报道。
