A study on 60 patients with the cerebral lacunar infarction, ages of 20-85 and 60 patients with cerebral infarction (control), ages of 20 -87 has shown that the syndromes of cerebral lacunar infarction comprised hemiplegia type of merely moving, speaking disorder hemiplegia type of combination of sense and moving, merely sense accident and other lacunar syndromes. The risk factors of diseases were hypertension, diabetes and smoking.

A study on 114 patients at the Mental Department and Emergency Department in the General Nghe An Hospital from Aug 2002 to Aug 2004 showed that: cerebral stroke is common disorder in neurology. Cerebral hemorrhages patients have some symptoms such as: conscious disorders (90.5%); headache (95.2%); encephalic infarction with hemiplegia 72.2%. Cerebral hemorrhages with sudden onset (76.2%), serious conscious disorder (71.4%), headache (66.7%), and vomiting (57.1%), orbicularis disorder (80.9%), meningitis syndrome (57.1%). Although encephalic infarction onset is more serious, its symptoms are much lower than cerebral hemorrhages. The average blood pressure in patients with cerebral hemorrhages is higher than that in patients with encephalic infarction. 87.7% patients have one lesion nest identified by computed tomography (CT) scanner, in which infarction-hemorrhagic lesion was 7%. The method has high value in differential diagnosis between cerebral hemorrhages and cerebral infarction with the sensitivity of diagnosis of cerebral hemorrhages was 88.8% and encephalic infarction was 90.9%, the overall accuracy was 93.7%. Because the SIRIRAJ grade is simple, easy to count and mainly based on questioning patients, so it should be applied widely for doctors at community centers without CT scanner.

Contrary to ventricular mural thrombi, left atrial appendage thrombi are extremely rare in cerebral infarction correlated with acute myocardial infarction but they can be easily detected by transesophageal echocardiography(TEE). We expierienced a case of cerebral infarction which was suspected to be caused from the thrombi in left atrial appendage in a patient with acute myocardial infarction. The cerebral infarction was developed 2 days after myocardial infarction had been occurred and any source of the thrombi could not be detected except in left atrial appendage. The diagnosis was established by TEE and also aided by transthoracic echocardiography, brain computed tomography.

60 subjects with brain lacunar infarction and 60 with other brain (no lacunar) infarction aged 20-67 were investigated in Bach Mai Hospital from Jan 2001 to Jun 2002. The proportion of brain lacunar infarction vs other brain infarction was 38% in the same duration. 5 main syndromes of lacunar infarction were 98%, other syndromes 2%. There is no difference in age and gender of both groups. Risk of complications of brain lacunar infarction raised by 8,9 times in comparing with high blood pressure, 6,5 times with smoking, 2,3 times with diabetes

A 59-year-old man with multifocal cerebral infarction was found to have the large obstructive mitral valvular mass. Although benign tumor was under suspicion before surgery, he was finally diagnosed as chronic infective endocarditis by microscopic evaluation. The precise diagnosis and the proper management of a cardiac mass are very important since even the benign tumor may cause fatal complications. However, primary cardiac mass has the broad spectrum from pseudo-tumor to malignancy and the differential diagnosis using non-invasive methods is not easy even with the currently available imaging techniques.

Multiple cardiac myxomas are rare in children. However, myxomas may be lethal because of their various manifestations such as blood flow obstruction, embolization and constitutional changes. Especially, the cerebral infarction due to tumor fragmentation are more likely to be misdiagnosed of acute disseminated encephalomyelitis. We report a case of multiple cardiac myxoma complicating recurrent right hemiparesis in a 12-year-old child who at first had a wrong diagnosis of acute disseminated encephalomyelitis (ADEM). Consequently, a child who show unrepresentative symptom of ADEM, should be examined rapidly by various tools to rule out the cerebral infarction from cardiogenic cause.

PURPOSE: To compare the detection rate of unenhanced CT, spin-echo T2-weighted, fast fluid-attenuatedin-version- recovery(FLAIR), and diffusion-weighted MR imaging in the diagnosis of hyperacute middle cerebralartery(MCA) territory infarction. MATERIALS AND METHODS: Sixteen patients with clinically proven hyperacute MCAterritory infarction were e-valuated with unenhanced CT and MR. All CT examinations were performed within sixhours of the onset of symptoms and all MR studies were performed within two hours of CT. All images were evaluatedindepen-dently by two radiologists in possession of brief clinical information. Positive imaging criteria wereparenchy-mal hypoattenuation, as seen on CT, and increased signal intensity, as seen on MR. For quantitativeanalysis, we measured the attenuation and signal intensity of the lesion and contralateral normal parenchyma, andper-centage contrast-to-noise ratios(CNRs) of the lesions were also calculated. RESULTS: Positive findings weredetected in all patients on diffusion-weighted images, in 13(81%) on CT, in 10 ( 63 %) on fast FLAIR images, andin 7(44 %) on T2-weighted images. Lesion percentage CNRs were 30% for diffusion-weighted imaging, 15 % for CT, 18% for FLAIR MR imaging, and 16 % for T2-weighted MR imag-ing(p < .004 for diffusion-weighted imaging vs others). CONCLUSION: For hyperacute MCA territory infarction, diffusion-weighted MR imaging was the most sensitive imagingtechnique and unenhanced CT was superior to fast FLAIR or T2-weighted imaging.

Spontaneous anterior cerebral artery (ACA) dissection, although extremely rare, is often associated with severe morbidity and mortality. It could lead to cerebral hemorrhage, ischemic stroke, or, rarely, combination of hemorrhage and ischemia due to hemodynamic changes. Prompt and accurate diagnosis is essential for determining the appropriate management. However, the optimal treatment for ACA dissection remains controversial. Herein, we report on two rare cases of subarachnoid hemorrhage (SAH) caused by ACA dissection; a case presenting with simultaneous SAH and infarction without aneurysmal formation and another case presenting with SAH with fusiform aneurysmal formation. A review of the related literature is provided, and optimal treatments for each type of dissection are suggested.
