The lesions of the cerebral white matter which characterize Pelizaeus-Merzbacher disease are classically observed at pathological examination. An early diagnosis can now be obtained by magnetic resonance imaging (MRI). In an eutrophic first son born at term, stridor, nystagmus-like eye movements and axial hypotonia were noted immediately after birth and(More)
Cerebral sulci identification process is based on several formal rules: it consists a series of steps allowing the identification of the major sulci. The process may be variable for each of us and we propose to read the images in certain order starting with the frontal lobe and its superior frontal gyrus than precentral and central gyri followed by the(More)
The authors report a case of secondary worsening of neurological symptoms in a patient 2 months after cord injury at T5 causing paraplegia. The MRI showed myeolomalacia, which appears as cord oedema, located in the grey matter, extending increasingly from the initial lesion (eighth thoracic vertebra) to the bulb. This cord lesion known as grey matter(More)
Correlation of myelin-stained or cryotomic sections of human brain with inversion-recovery MR images can display the cerebral commissures as white-matter tracts (in hypersignal on MRI), crossing the mid-line. MRI shows routinely in three orthogonal planes a) the corpus callosum stretched above the supra-tentorial ventricles, it's four portions (rostrum,(More)
MR Imaging has become the procedure of choice for the exploration of the pituitary region. MR contrast resolution is far better than the finest CT examination, especially concerning the microadenomas and the neurohypophysis. The present paper concerns, at first the major principles of magnetic resonance imaging, its application for the study of the(More)
