Results MRI findings of central neurocytoma are specific in 5 cases. The ganglioglioma was found in the tempora and occipital lobe in 7 cases,in the brainstem in 1 case, cystic-solid tumor was observed in 5 cases with extramural nodule in 3 cases, obviously thickened gyri were revealed in 1 cases and central necrosis in 2 cases.The 3 cases of Lhermitte-Duclos disease include the specific molecular layer imaging features.

结果 5例中枢神经细胞瘤有一定的MRI特征，3例诊断正确。8例神经节细胞胶质瘤中，7例位于或主要位于颞、枕叶，1例位于桥脑和延髓，表现为囊实性者5例，实性部分位于囊外的有3例，呈实性表现为局部脑回增厚者1例，囊变坏死明显者2例。3例小脑发育不良性节细胞瘤有特征性的条纹状或分层状表现。

Mid-line shift(81%), lateral cerebral ventricle allaxis due to be compressed(67%), plica of cerebral convolution gather together and ingression(89%) and grey matter of brain ingression(78%) were seen in the cases.

并中线结构移位占81%，侧脑室受压变形占67%，脑回皱襞聚拢内移占89%，脑灰白质内移占78%。

Cognition disturbance and allolalia were the chief clinical manifestations. The imageology showed that the impairment involved occipital lobe and temporal lobe most. 17 cases presented red-ragged-fibres and parking lot-like ultrastructure in 3 cases. Brain biopsy showed layerage structure. There were 15 of them carried mtDNA A3243G mutation. Conclusions MELAS Syndrome usually involved central nerve system and skeletal muscle.

主要临床表现为认知功能障碍及言语障碍，头颅影像学检查示枕叶、颞叶脑回受累为主。18例行肌肉病理检查显示17例存在破碎样红纤维，3例行肌肉电镜检查发现线粒体堆积呈停车场样排列，3例脑活检示病变皮层组织呈分层样改变，15例发现mtDNA A3243G点突变。

Verbal dyspraxia may result from damage to Broca's area, the supramarginal gyrus, supplementary motor area, frontal operculum, and insula.

General morphology manifested that the edema was distinct in the right cerebral hemisphere in the control group, showing fat-like white, shallow an- fractuosity, flat gyria, brittle tissue and easy to break up.

大体形态学表现为对照组右侧大脑半球水肿明显，颜色呈脂肪样苍白，脑沟变浅，脑回变平，组织较脆且易碎。

The gyri are narrowed and the sulci widened toward to frontal pole.

脑回变窄，通向额极的脑沟变宽。

Broad, flat gyri with shallow sulci focal or widespread

宽基底、扁平的脑回，脑沟变浅。

The anterior part of Rolandic vein (n=1), Rolandic vein (n=3), the posterior part of Rolandic vein (n=2), straight sinus (n=1), straight sinus and sinus confluens (n=1) were embolized. On MRI, gyrus swelling, brain swelling or slight ventriculomegaly, and cerebral hemorrhage (n=2), subdural hemorrhage(n=2) were observed.

Rolandic静脉处栓塞3例，Rolandic静脉后栓塞2例，直窦栓塞1例，直窦和窦汇栓塞1例，MRI显示有不同程度脑回肿胀、脑肿胀或轻度脑室扩大，伴脑出血2例，硬膜下出血2例。

Results: Various extent of gyrus-like or banded calcifications were showed in cortex of 8 all cases, cerebral hemisphere atrophy in 4 cases and thickened skull in 3 cases on the diseased side were accompanied. Ocular hemangioma of choroid and choroids plexus enlargement of lateral ventricle were found in one case. The clinical symptoms and signs of correspondence were found.

结果：8例脑颜面血管瘤综合征均有脑皮层不同程度的脑回样或条带状钙化，4例伴病侧大脑萎缩，3例伴病侧颅板增厚，1例合并眼部脉络膜血管瘤和侧脑室脉络丛增大。8例均出现与CT表现相对应的临床症状和体征。

Lissencephaly is a term used to described a brain with absent or poor sulci formation.

无脑回这个术语用于描述无或只有很少脑沟形成的脑。
