We report a case of hypereosinophilia causing multiple areas of cerebral infarcts. A 52-year-old Korean man presented with dysarthria and weakness in both arms. A brain MRI revealed multiple acute infarcts in the distal border zone with focal intracerebral hemorrhage, whereas a cerebral angiogram was not remarkable. The eosinophil count was 5,500/microLiter and was accompanied by elevated cardiac enzyme levels. The pattern of cerebral infarcts and laboratory results suggest a thromboembolic infarction associated with hypereosinophilia.

Phantom limbs are usually observed after amputation of extremities. In patients after a stroke, a similar but rarely occurring phenomenon consisting of the patient experiencing the presence of an additional limb has been described. This phenomenon, generally called supernumerary phantom limb (SPL), may be caused by lesions in the right or left cerebral hemisphere, but has been predominantly reported in patients who have had a right hemispheric stroke. We report two cases of atypical SPL and phantom limb pain (PLP) after pontine hemorrhage. The patients were treated conservatively and their symptoms lasted more than 1 month. This is the first report of SPLs after left pontine hemorrhage, and phantom perception and pain lasted longer than those in previously observed cases. Our results indicate that SPL may be more common than reported; therefore, thorough examinations are essential for the care of stroke patients.

OBJECTIVETo analyze the relationship between clinical characteristics and prognosis of neonatal cerebral infarction and to draw attention to the disease to improve the long-term outcome through early diagnosis and intervention.
METHODSThe clinical characteristics of 6 confirmed cases were summarized. Perinatal conditions and other factors were analyzed for possible causes of the disease. The survived patients were followed-up for 6-8 months.
RESULTSThe authors diagnosed 6 cases of neonatal cerebral infarction in one year, which accounted for 0.6% (6/969) of all the in-patients in the same time period. Among them 3 cases were confirmed as cerebrovascular malformations by magnetic resonance angiography (MRA), In 1 case the infarction was due to severe bilateral intraventricular hemorrhage, and in another case the disease was related to comprehensive factors such as prematurity, maternal pregnancy induced hypertension and respiratory failure secondary to bronchopulmonary dysplasia (BPD), and in 1 case the cause was undetermined. Four out of the 6 patients presented with varied forms of convulsions, which became the second leading cause for all the neonatal convulsive events (20%). None of the patients had localized neurological signs in the early course except for abnormal muscular tone of some extent. Cerebral ultrasound scanning in 5 out of 6 cases showed positive results. The diffusion-weighted magnetic resonance imaging (DW-MRI) was highly valuable for early confirmative diagnosis. Only one case was found normal within one year of follow-up and all the other 5 cases had unfavorable prognoses of varied severity.
CONCLUSIONNeonatal cerebral infarction is not a rare condition and should be considered as one of the important causes for neonatal convulsion. Imaging study is the main technique for diagnosis. The prognoses were poor for those cases for whom early diagnosis and treatment can not be made or those with widespread cerebral lesions.

OBJECTIVETo investigate the value of susceptibility weighted imaging(SWI)in the diagnosis of hemorrhagic foci early after blast injury and its role in the outcome prediction.
METHODSTotally 30 rabbits with blast-induced cerebral blast injury were used in this study. After routine CT/MRI and SWI scanning,quantified analysis was performed in regions of interest using post-processing technology. After dissecting the brains of the experimental rabbits,the cerebral histopathological changes were observed,and the results were compared with SWI findings.
RESULTSIn these 30 rabbits,22,102,221,and 738 hemorrhagic foci were detected by CT,T1WI,T2WI,and SWI,respectively. The number of cerebral microbleeds detected by SWI was significantly larger than those revealed by conventional T1WI and T2WI(Χ(2)=10.00,P<0.01). Furthermore,the SWI imaging displayed the punctiform(n=315,42.7%),lamellar(n=218,29.5%),slinar(n=205,27.8%)hypointense foci,with clear margin. The number of hemorrhagic foci detected by SWI was positively correlated with survival(r=-0.667,P<0.05).
CONCLUSIONSSWI remarkably increases the detection rate of hemorrhagic foci(particularly microbleeds)in rabbits with cerebral blast injury. The number of cerebral microbleeds and location of foci are closely related with the outcomes and therefore may facilitate clinical managment.

We report here on a neonate with congenital cerebellar mixed germ cell tumor, and this initially presented as cerebellar hemorrhage. Postnatal cranial ultrasonography revealed an echogenic cerebellar mass that exhibited the signal characteristics of hemorrhage rather than tumor on MR images. The short-term follow-up images also suggested a resolving cerebellar hemorrhage. One month later, the neonate developed vomiting. A second set of MR images demonstrated an enlarged mass that exhibited changed signal intensity at the same site, which suggested a neoplasm. Histological examination after the surgical resection revealed a mixed germ cell tumor.

Paragonimiasis is caused by ingesting crustaceans, which are the intermediate hosts of Paragonimus. The involvement of the brain was a common presentation in Korea decades ago, but it becomes much less frequent in domestic medical practices. We observed a rare case of cerebral paragonimiasis manifesting with intracerebral hemorrhage. A 10-yr-old girl presented with sudden-onset dysarthria, right facial palsy and clumsiness of the right hand. Brain imaging showed acute intracerebral hemorrhage in the left frontal area. An occult vascular malformation or small arteriovenous malformation compressed by the hematoma was initially suspected. The lesion progressed for over 2 months until a delayed surgery was undertaken. Pathologic examination was consistent with cerebral paragonimiasis. After chemotherapy with praziquantel, the patient was monitored without neurological deficits or seizure attacks for 6 months. This case alerts practicing clinicians to the domestic transmission of a forgotten parasitic disease due to environmental changes.

OBJECTIVETo set up a new grading system of intraventricular hemorrhage (IVH) and determine the value of predicting the probability of post-hemorrhagic hydrocephalus (PHH) in IVH.
METHODSWe first modified the Graeb criteria, then compared the value of prediction for PHH assessed by the Graeb criteria with the modified Graeb criteria. One hundred and thirty one IVH patients were divided into two groups: the upper group (n = 67) and the lower group (n = 64). Gold standard of PHH was assessed by CT scan or by out-drainage. The diagnostic parameters such as sensitivity (SE), specificity (SP) were analyzed. In the cutoff point of SE and SP curves, diagnostic efficiency (DE), and Kappa value (K) were analyzed. The probability of PHH was estimated by binary logistic regressions.
RESULTSIn all ventricular group, to Graeb criteria in the cutoff point, SE, SP, and K was 0.78, 0.84, and 0.60; and to modified Graeb criteria SE, SP, and K was 0.90, 0.84, and 0.74 respectively. The probability of PHH from point of 3-12 was 0.011, 0.032, 0.085, 0.212, 0.435, 0.689, 0.865, 0.949, 0.981, and 0.994 respectively according to modified Graeb criteria.
