Leukoencephalopathy with brainstem and spinal cord involvement and lactate elevation (LBSL) is a recently described disorder with autosomal recessive mode of inheritance. Lately, mutations in the DARS2 gene, which encodes mitochondrial aspartyl-tRNA synthetase, have been found as the underlying defect. We report a 19-year-old male patient with cerebellar,(More)
Magnetic resonance imaging (MRI) depicts infectious foci in the perianal region better than any other imaging modality. MRI allows definition of the fistula, associated abscess formation and its secondary extensions. Accurate information is necessary for surgical treatment and to obtain a decrease in the incidence of recurrence and complications.(More)
Intracranial lipomas (ICLs) are rare lesions, the vast majority encountered as incidental findings on imaging studies. ICLs are generally pericallosal midline lesions and thought to be asymptomatic and can be accompanied by additional intracranial congenital malformations. We describe a 17-year old male with an unusual case of ICL on the frontal lobe(More)
Spinal arteriovenous malformations (AVMs) may be associated with sensory and motor deficits, bowel or bladder dysfunc-tion, radicular pain or deficit, and back pain. Hemorrhage can occur in the parenchyma leading to the acute onset of symptoms. Neurosurgical resection is one of the way of treatment. Several techniques including intraoperative angiography,(More)
Where fuzzy regression can be applied and, in which conditions fuzzy regression method more appropriate tool for the investigations are identified in this paper. The contrast between fuzzy regression and ordinary regression analysis and three approach of fuzzy regression are summarized. In this paper, we estimated the values of the parameters in the(More)
PURPOSE To compare the diagnostic values of fluid-attenuated inversion recovery (FLAIR) and gradient spin-echo (GRASE) with those of conventional spin-echo (SE) and fast SE T2-weighted sequences in the evaluation of acute cerebrovascular lesions at 0.5 T. MATERIAL AND METHODS Twenty-two consecutive patients with the clinical diagnosis of acute(More)
Langerhans cell histiocytosis (LCH) is a disease of unknown cause characterised by proliferation of histiocytic granulomas in tissues; the primary cerebral manifestation is diabetes insipidus caused by hypothalamic infiltration. We present a patient in whom, except for the absence of high signal on T1 weighting in the posterior pituitary, consistent with(More)
