Forceps were applied to the fetal head for failure to progress. Apgar scores were 6 and 9. within the 1st day of life, the

2、baby was observed to be listless and lethargic and to have a poor suck. The anterior fontanelle was tense. Seizures developed. Endotracheal intubation and ventilation were required for bradycardia and apneic episodes. The hemogram was normal. A lumbar puncture was performed to rule out central nervo

3、us system sepsis, and bloody cerebrospinal fluid was obtained. CT was then performed, and a large PFSDH was observed in addition to moderate ventriculomegaly. A neurosurgical consultation was obtained. The neonate was quadriplegic on a ventilator , making only the occasional respiratory effort. The

4、neonate was taken urgently to surgery, and a posterior fossa craniectomy was performed. The clot could be removed from the posterior fossa subdural space. The bleeding sites were identified and successfully coagulated. The infant did not require an external ventricular drain nor did she go on to dev

5、elop progressive hydrocephalus. She began to breathe readily after the posterior fossa decompression and clot evacuationn. She was weaned from the ventilator within 4 days. Subsequent CT showed minimal left cerebellar parenchyma involvement with calcification and volume loss. The ventriculomegaly ha

8、48-year-old male who presented with complaints of increasingly severe headaches. Workup at another hospital revealed a lucent left frontal lesion. The biopsy diagnosis was grade m astrocytoma. He was referred to our hopsital after external radiation therapy was delivered. Neurological exam revealed

9、mild bradykinesia, but was otherwise unremarkable. He was admitted and underwent a left frontal lobectomy, with gross total tumor resection. One month later he underwent stereotactic implantation of brachytherapy catheters. He received 6000 rads to the margin of the tumor cavity. Subsequent scans re

10、vealed progressively worsening enhancement, edema, and shift around the tumor cavity. Reoperation was undertaken with resection of all grossly abnormal tissue. Pathologic analysis revealed radiation necrosis and tumor. The patient is alive 5 years later, with no evidence of disease progression. 额叶星形

11、细胞瘤 一男性患者， 48 岁，自诉进行性剧烈头痛数日，在某医院检查示有左额叶高亮度损害，活组织 检查诊断为三级星形细胞瘤，在外院应用放疗后，被送入我院。神经系统检查，表明有轻微的 运动过缓，但并不明显。入院后行肿瘤全切及左额叶切除术。一个月后，他接受了立体定向导 管穿刺移植治疗，在肿瘤腔的边缘吸收6000 拉德进行照射，随后CT 扫描显示有进行性的瘤腔扩大，周围水肿，并伴有瘤腔移位，再次手术全切了异常组织，病理分析回报，这些异常组织 包括放疗后的坏死组织和肿瘤细胞。患者出院后 5 年，随访无明显的疾病进行性发展的迹象。Case 6Glioblastoma multiforme of fron

12、tal lobeA healthy 9-year- old woman presented with a 3-month history of dysphasia. Computed tomography demonstrated a ringenhancing lesion in the right frontal lobe. She was not immunosuppessed or on steroids. The rim was T2 hypointense and T1 hyperintense. There was a small amount of surrounding ed

13、ema. Brain abscess was considered in the differential diagnosis, but a tumor was believed more likely, because: there wase an eccentric area of capsular thickening, edema was minimal, and the clinical caurse was long. At operation, glioblastoma multiforme was encountered. Substances with unpaired el

14、ectrons exhibit an unusual combination of increased T1signal and decreased T2 signal termed paramagnetism. Methemoglobin, melanin, and gadolinium are familiar paramagnetic substances. In an abscesscapsule, paramagnetic changes occur because macrophages release free-radicals that contain unpaired ele

Although uncommon, clinicians should be aware that paramagnetic rim signal may also be observed in metastasis, primary brain tumors, granulomas like tuberculosis, and in large demyelinating plaques.额叶多形胶母细胞瘤一 6 岁女孩有 3 个月的言语困难病史， CT 检查显示在右侧额叶有一环形增强的损害，她没有免疫抑制也没有应用过类固醇，此损害的边缘在 MRI T2 像为低信号， T1

A scan was done in February and this demonstrates an area of nonenhancement in the posterior portion of the superior frontal convolution, with a small contrast enhancing area

19、 in the center of the lesion. The latter approximately 3 mm, the former measures approximately 3.5 cm. The scan was repeated recently and it appeared that the lesion had grown slightly. Stereotactic biopsy was recommended. The patient in fact was scheduled for a biopsy in Hebei but they decided to s

Radiographic studiesMRI scan shows an approximately 3.5 cm well-demarcated lesion in the posterior aspect of the left superior frontal convolution.ImpressionProbable low/intermediate grade glioma, possibly ganglioglioma or ganglio-n

23、eurocytoma. If the lesion is anterior to the motor cortex, resection is recommended. If the lesion is within the motor cortex, a biopsy is recommended.Hospital courseThe patient underwent magnetoencephalography(MEG) to map his primary motor cortex and define its relationship to the tumor. This confi

24、rmed the clinical and radiographic impression that the tumor was anterior to the motor strip.A stereotactic volumetric resection of the lesion was then performed. The volume of the tumor, based on the contrast-enhancing portions on both CT and MRI, as well as from the area of abnormality on T2-weigh

25、ted MRI, was digitized for computer targeting. A view of the cortical surface after the trephine craniotomy was performed. A strip electrode placed onto the cortical surface in a direction posterion to the edge of the trephine confirmed the location of sensorimotor cortex by phase reveral.The tumor

26、volume can be superimposed onto the field of view of the operating microscope, to assist the surgeon in defining the margins of the tumor. The lesion was dissected away from the surrounding brain tissue at its inerface and was removed as a single specimen.The patient s neurologic function postoperat

Magnetic resonance imaging performed after gadolinium injection showed a caput medusae-like enhancement in the left cerebellar hemisphere. In the same area cerebral angiography demonstrated a characteristic venous angioma with drainage
