Multiple sclerosis (MS) is an inflammatory demyelinating disease of the central nervous system, predominantly affecting the white matter, but also the grey matter. Aim of this study was to detect MS lesions with double inversion recovery (DIR), fluid-attenuated inversion recovery (FLAIR) and T2-weighted magnetic resonance (MR) techniques and determine the sensitivity of these techniques, and the correlation between the number of lesions and expanded disability state scale (EDSS) scores. Thirty-four patients with MS (20 females and 14 males) were included in this study. DIR and conventional MR (T2-A, FLAIR) sequences were obtained. Lesions were counted and classified as belonging to one of seven anatomical regions: cortical, juxtacortical, deep grey matter, deep white matter, mixed white matter-grey matter, periventricular white matter and infratentorial. The correlation between lesion number and EDSS scores was investigated. DIR images showed more intracortical and mixed white matter-grey matter lesions in comparison with both FLAIR and T2 sequences (p=0, p=0 respectively). There was a significant difference between mean lesion numbers at the juxtacortical region, obtained with DIR and T2-weighted images (p = 0.002). The total number of lesions obtained with all methods was similar. DIR brain imaging had the highest sensitivity in the detection of cortical and mixed white matter - grey matter lesions, compared with FLAIR and T2 sequences. In addition, the lesions obtained with DIR images were more easily visualized.

SUMMARY -Multiple sclerosis is a chronic inflammatory demyelinating disease of the central nervous system. Diffusion tensor magnetic resonance imaging (DTI) can yield important informa

Visual and oculomotor signs and symptoms are common and well defined in patients with multiple sclerosis. On the other hand, the phenomenon of "upside-down" reversal of vision is very rare and thus not well known. The physiopathology of this phenomenon also has not been well understood. Herein, we present a female patient with multiple sclerosis, who developed acute "upside-down" visual inversion, and discuss possible mechanisms of this rare phenomenon.

Rhabdomyolysis is a life threatening syndrome. It accounts for an estimated 8% to 15% of cases of acute renal failure and is associated with a mortality rate of 5%. In movement disorders, various causes of rhabdomyolysis have been reported including status dystonicus, myoclonus, generalized chorea and parkinsonism-hyperprexia syndrome in Parkinson’s disease (PD). Levodopa-induced dyskinesia leading to rhabdomyolysis is a very rare phenomenon in PD. We report a case of 76 years old PD patient with dyskinesia and rhabdomyolysis.
