RESUMO
Background: Basal ganglia hemorrhage (BGH) is an intracerebral subtype of hemorrhage located in the caudate nucleus, putamen, globus pallidus, or adjacent structures such as the thalamus or internal capsule. Bilateral involvement of both basal ganglia is exceedingly infrequent. Herein, we report a case of a 2-year-old female who was discovered to have spontaneous bilateral BGH with a unique hemorrhagic extension. Case Description: A 2-year-old female child who presented with a decreased level of consciousness, seizure, and fever was discovered to have bilateral BGH during imaging evaluation that extended from the head of the caudate to involve the putamen, globus pallidus, and anterior limb of the internal capsule. Conclusion: Bilateral BGH is extremely rare, and to the best of our knowledge, this is the first case report in pediatric age groups.
RESUMO
Moyamoya disease is a chronic and unusual cerebrovascular disorder characterized by progressive stenosis and occlusion of the distal portions of internal carotid arteries and its main branches within the circle of Willis. Posterior circulation (vertebral and basilar arteries) may also be affected; however, this presentation is uncommon. As well as stenosis of the terminal portion of intracranial arteries, it is seen the development of a network of collateral vessels abnormally dilated at the base of the brain with an aspect of a "puff of smoke," whose term in Japanese is described as "moyamoya." The present study aims to report two consecutive cases of patients who presented to our service with different clinical manifestations. Further investigation with digital subtraction angiography showed a moyamoya pattern.
