ABSTRACT: To investigate the clinical and radiological characteristics of cortical vein thrombosis for early diagnosis and treatment.
Retrospective analysis was carried out with the clinical cases of cortical vein thrombosis in 2010. The symptoms, sign, neuroimaging were analyzed and related literatures were reviewed.
Four patients were collected, average age was forty years old. The main symptoms were headache and focal neurological signs in varying degrees, infarction or hemorrhage in one or two sides of parietal lobe could be found in CT or MRI. Hemorrhage was found in two patients, infarction was found in one patient, hemorrhage and infarction were both found in another patient.
Headache and focal neurological signs are the common sings and symptoms of patients with cortical vein thrombosis. CT and MRI are effective methods for the diagnosis of cortical vein thrombosis.

ABSTRACT: To analyze the neurological manifestations of chronic mercury poisoning for the improvement of clinical understanding of this disease.
The clinical data of 8 cases diagnosed as chronic mercury poisoning admitted in the department of neurology of Xuanwu hospital during the past 5 years were collected and analysed.
Neurological manifestations of chronic mercury poisoning involved psychological problems, sleep disorders, ataxia, extremities weakness and atrophy, tremor, peripheral neuropathy and paresthesia.
There are various kinds of neurological manifestations of chronic mercury poisoning. Identification of these manifestations in clinical practice and early diagnosis are beneficial for the relief of pains in the patients.

ABSTRACT: To summarize and analyze the clinical features of Hirayama disease.
The authors summarized the clinical data of 29 cases of Hirayama disease in recent 9 years.
All of the 29 cases were male and the age of onset was 12 - 25 years. 22 of the 29 patients only had the symptoms of one upper limb and 7 of them had symptoms of both upper limbs. Most of them had symptoms on the right or the symptoms were on more severe in the right than left, while only one case had symmetric symptoms of both upper limbs. The arm appeared as a slope, this was due to partial muscular atrophy. EMG indicated that the impairment of spinal anterior cells were limited to the arm relevant segments and both sides were involved. Cervical MRI scan suggested spinal atrophy at the level of C(5 - 7) vertebral bodies, being asymmetric in most of the cases. The atrophy was more obvious on the side with more severe symptoms. There was one patient whose MRI showed high T(2) signal in the spinal anterior cells of the C(5 - 6) segments. All the cases used cervical supporter and were followed up for 1 - 5 years. All of them had good prognosis.
Hirayama disease is more common in men with hidden onset before 20 years of age. Most of the patients noted the symptoms of hands gradually about 2 years after a period of rapid growth in height in adolescence. The predominant clinical manifestations are as follows: atrophy of lower cervical cord in cervical MRI, asymmetric spinal atrophy in horizontal impaction and the degree of atrophy consistent with the symptoms of limbs. EMG could indicate bilateral spinal anterior impairment in lower cervical cord. Rare case may present the abnormal signal in the spinal cord, but pyramid signs were absent.
