The association of type 1 diabetes mellitus (T1DM) and acute chorea is rare. We report an 8-yr-old boy with T1DM who developed acute hemichorea-hemiballism of the right arm in whom magnetic resonance imaging (MRI) of the brain revealed hyperintense signal in putamen and considerable atrophy and focal area of gliosis in the right putamen. There was a(More)
Hypothalamic hamartomas are very rare (1:200,000) and range in size from 17.9 to 18 mm. When their dimensions exceed 30–40 mm, they are classified as giant hypothalamic hamartomas. We present a 14-month-old boy with central precocious puberty and gelastic seizures in whom a magnetic resonance imaging scan revealed a giant hypothalamic hamartoma measuring 50(More)
The Virchow-Robin spaces (VRS) are subpial invaginations making a tubular revestment scabbard that contains a vase between the subarachnoid and subpial spaces. The magnetic resonance imaging (MRI) is the only imaging method able for evaluate this anatomic detail. We studied the possible association between dilated VRS and migraine. Seventy patients with(More)
We report a case of intramedullary cavernous angioma in a 56 years old woman with history of back pain. MRI show discal protrusion and disclose an intramedullary lesion, with heterogeneous sinal. The MRI is more sensitive than CT and the most appropriate technique is the sequence eco-gradient. The diagnosis is relevant because there is a possibility of(More)
We report a case of mansonic schistosomiasis with portal systemic encephalopathy associated with a high intensity signal in basal ganglia on TI weighted images due to deposition of manganese in tissues related with portal-systemic collateral vessels. A bibliographic review was done focusing the magnetic resonance findings. To the best of our knowledge,(More)
The purpose of this study is to evaluate morphological and signal intensity changes in the hippocampus in patients with medically intractable temporal lobe epilepsy. We studied 8 patients with mesial temporal sclerosis using a 1.5 -T MR and the following sequences Spin Eco- SE, Fast Spin Echo- FSE, Fluid Attenuation Inversion Recovery Echo Planar(More)
The posterior reversible leukoencephalopathy syndrome (PRES) is a recently proposed cliniconeuroradiologic entity. The most common causes of PRES are hypertensive encephalopathy, eclampsia, cyclosporin A neurotoxicity and the uremic encephalopathies. Most patients are markedly hypertensive at presentation, although some have only mildly elevated or even(More)
