[Magnetic resonance and magnetic resonance angiography in the diagnosis of vascular anomalies in childhood]. / Magnetna rezonanca i magnetna angiografija u dijagnostici vaskularnih anomalija djecijeg uzrasta.

UNLABELLED: The aim of this study is to demonstrate the accuracy of MRI and MR angiography, using 3D and 2D TOF sequences to diagnose vascular malformation in children with non-traumatic intracranial hemorrhage (subarachnoid or intracerebral hemorrhage). PATIENTS AND METHODS: In two years period 7 children, 4 boys and 3 girls range age 8 to 14 years with non-traumatic intracranial hemorrhage were examined on 1.0 TMR unit, using T1,PD,T2 WI and 3D and 2D TOF MR angiography with MIP reconstruction. RESULTS: In the group of 7 children, 2 were with aneurysms, 2 with AV malformation, and 1 with cavernous angioma. The results of these were correlated with those of IA DSA. The results were in agreement regarding the presence, location and size of aneurysms, the presence, vasculation and drenage of AV malformation. CONCLUSION: MRI with MR angiography is rapid and non-invasive examination which can confirm the diagnosis of vascular anomalies in children and to follow them up.

[Characteristics of computerized tomography of the brain in congenital hemiparesis]. / Karakteristike nalaza kompjuterizirane tomografije mozga kod kongenitalne hemipareze.

Congenital hemiparesis is defined as an unilateral disorder of movement and posture, with clinical signs of spasticity with flexor hypertonicity, increased tendon reflexes and characteristic posturing. We have examined a group of 26 children with congenital hemiparesis (14 boys and 12 girls) with mean age of 3.5 years (range 6 months to 9 years). 24 had been born at term (% weeks gestation) and 2 were preterm (% completed weeks gestation). From the neuroimaging point of view, congenital hemiparesis form a rather heterogeneous group. CT scans revealed: porencephalic cyst (6), unilateral ventricular enlargement (2), cortical atrophy with unilateral ventricular enlargement (1), hypodense zones resulting from previous hemathermous (4), normal CT scans (6), and 7 cases have not had CT scans for technical reasons (war conditions). Congenital hemiparesis mainly affects term children with prenatal origin in majority of cases. Vascular occlusions (in utero stroke) originating from various pathophysiological factors, maternal or fetal, may result in congenital hemiparesis. Normal CT findings should be revised by using MRI, which provides direct evidence of white matter lesions.
