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.
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.
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.
Fifteen cases of degenerative cerebellar atrophy are presented together with the criteria used to assess the diagnosis of cerebellar atrophy by computed tomography.
A case of brain-stem hemangioma calcificans is described. The few cases reported in the literature prove the rarity of this tumor, which is considered a benign variant of cerebral cavernous hemangioma. Diagnosis and treatment of these tumors are briefly discussed with a review of the literature including 11 previous cases.
This paper reports on a novel strategy and related algorithm for realizing dynamic routing and grooming into wavelengths of data flows (label switched paths, LSPs) in new generation optical networks based on generalized MPLS (GMPLS). The method allows arbitrary granularities of LSPs. The new generation network is modeled as a multi-layer network consisting… (More)
This paper reports a traffic engineering (TE) strategy that is able to handle several GMPLS classes of services dynamically. Based on the extension of the hybrid TE strategy previously introduced by the authors, in the present paper dynamic managing of more classes of services is addressed and related performance analysis is reported. The main results show… (More)
This article provides an overview of the computed tomography (CT) and MR imaging appearances suggestive of spondyloarthritis, with a specific emphasis on the MR imaging findings of vertebral and sacroiliac involvement, and presents relevant clinical features that assist early diagnosis. CT is a sensitive imaging modality for the assessment of structural… (More)
The spinal pain, and expecially the low back pain (LBP), represents the second cause for a medical consultation in primary care setting and a leading cause of disability worldwide . LBP is more often idiopathic. It has as most frequent cause the internal disc disruption (IDD) and is referred to as discogenic pain. IDD refers to annular fissures, disc… (More)
