Purpose:
@EN Bilateral high signal intensity in basal ganglia on T1-weighted images in unusual, the purpose of this study is to describe the of high signal intensity, and underlying disese.
@ES Methods and Materials:
@EN During the last three years. 8 patients showed bilateral high signal intensity in basal ganglia on T1-weighted image, as compared with cerebral white matter. Authors analized the images and underlying causes retrospectlvely. Of 8 patients, 5
were
male and 3 were female. The age ranged from 15 days to 79 years. All patients were examined by a 0.5T superconductive MRI image were obtained by spin echo multislice technique.
@ES Results:
@EN Underlying causes were 4 cases of hepatopathy, 2 cases of calcium metabolism disorder, and one case each of neurofibromatosis and hypoxic brain injury. These process were bilateral in all cases and usually symmetric. In all cases the
hyperintense
areas were generally homogenous without mass effect or edema, although somewhat nodular appearence was see in neurofibromatosis. Lesions were located in the globus pallidus and internal capsule in hepatopathy and neurofibromatosis, head of the
caudate
nucleus in disorder of calcum metabolism and the globus pallidus in hypoxic brain injury.
@ES Conclusion:
@EN Although this study is limited by its patients population, bilateral hyperintense basal ganglis is associated with various disease entities. On analysis of hyperintense basal ganglia lesion, the knowledge of clinical information improved
diagnostic
accuracy.
