We report a 13-year-old girl with leukaemia and Wernicke's encephalopathy induced by total parenteral nutrition. MRI showed unusual bilateral lesions of the caudate nuclei and cerebral cortex, as well as typical lesions surrounding the third ventricle and aqueduct. After intravenous thiamine, the patient improved, and the abnormalities on MRI disappeared.
The authors describe 3 cases of the extracranial Vertebral artery fenestration. This anomaly is a rare case seen in autopsy and angiographically, and in literature too the cases described are few and prevalently by Japanese authors. This anomaly is important because frequently is associated with others congenital intra and extracranial vascular… (More)
MR in a patient with Wernicke encephalopathy showed enhancement in the mamillary bodies and inferior quadrigeminal plate. These findings pointed to the correct diagnosis, which can be difficult to make in patients who are not alcoholics.
Fifteen cases of degenerative cerebellar atrophy are presented together with the criteria used to assess the diagnosis of cerebellar atrophy by computed tomography.
We evaluated the potential of MR sequences with Fat Saturation and gadolinium in patients with degenerative disease of the lumbar spine and low back pain, by studying both anterior and posterior elements of the lumbar spine. We examined 3323 patients (age range 15-78 years) presenting low back pain. We used T2-weighted sequences with Fat Saturation and in… (More)
We examined 21 patients with ischemic cerebrovascular disease using magnetic resonance angiography and transcranial Doppler. In 17 patients (81%), the results obtained by the two methods were concordant. In our opinion, the associated use of transcranial Doppler and magnetic resonance angiography provides an accurate diagnostic evaluation of ischemic stroke… (More)
We report a case of thrombotic thrombocytopenic purpura evaluated by MR. Multiple hyperintense foci on the T2-weighted images, observed principally in the brain stem and in the region of the basal nuclei, and neurologic signs disappeared after 15 days of therapy.
A 77 year old woman was hospitalized one hour after the onset of right hemiplegia and aphasia. Magnetic resonance imaging (MRI) examination was negative and MRA indicated occlusion of the left middle cerebral artery. Treatment with streptokinase was instituted (a 60 minute intravenous infusion of 1.5 MU of streptokinase in 100 ml of saline solution). Two… (More)
Intra-arterial digital subtraction angiography was performed in 25 patients, using Iopamidol in three different iodine concentrations: 50, 75, and 100 mg I/ml and comparing the results obtained with each concentration. The following vessels were explored: the aortic arch, the common carotid artery, the internal and external carotid arteries and the… (More)
