Abstract
Thanatophoric dysplasia, achondroplasia, and hypochondroplasia belong to the () group of genetic skeletal disorders. Temporal lobe abnormalities have been documented in thanatophoric dysplasia and hypochondroplasia, and in 1 case of achondroplasia. We retrospectively identified 13 children with achondroplasia who underwent MR imaging of the brain between 2002 and 2015. All children demonstrated a deep transverse temporal sulcus on MR imaging. Further common neuroimaging findings were incomplete hippocampal rotation (12 children), oversulcation of the mesial temporal lobe (11 children), loss of gray-white matter differentiation of the mesial temporal lobe (5 children), and a triangular shape of the temporal horn (6 children). These appearances are very similar to those described in hypochondroplasia, strengthening the association of temporal lobe malformations in -associated skeletal dysplasias.
摘要
致死性骨发育不良、软骨发育不全和软骨-外胚层发育不良属于遗传性骨骼发育障碍的 () 组。在致死性骨发育不良和软骨-外胚层发育不良中以及在 1 例软骨发育不全中已有记录到颞叶异常。我们回顾性地确定了 2002 年至 2015 年间进行脑磁共振成像检查的 13 例软骨发育不全患儿。所有患儿的磁共振成像显示深横颞沟。进一步常见的神经影像学发现包括不完全的海马旋转（12 例患儿）、内侧颞叶过度脑回（11 例患儿）、内侧颞叶灰白质分界丧失（5 例患儿）和颞角呈三角形（6 例患儿）。这些表现与软骨发育不全中描述的非常相似，进一步证实了颞叶畸形与骨骼发育障碍的相关性。
