    Unspecific white matter lesions: prevalence, number and distribution in cranial MRI (1992)

    Notes: Abstract To establish data about prevalence, number and topography of “unspecific” white matter lesions as seen on MRI, the T2-weighted MRI scans of 83 patients with hyperintense focal white matter changes were reviewed. Patients with known inflammatory central nervous system disease were excluded. There was an approximately linear increase in prevalence and number of lesions with age. Prevalence ranged from 18% in the third decade to over 90% in those over 70 years. We found a close correlation with concomitant periventricular hyperintensity. However, rating of Virchow-Robin spaces did not correlate with the number of white matter lesions. Both hemispheres were involved nearly equally with a minimal non-significant right side preponderance. Lesions showed a strong predilection for the frontal and parietal paraventricular “watershed” areas.

    Do arachnoid cysts grow? (1991)
    Springer
    Neuroradiology 33 (1991), S. 341-345

    ISSN: 1432-1920

    Topics: Medicine
    Notes: Summary The volumes of intracranial arachnoit cysts were measured in 136 CT scans of 86 patients. Absolute and relative cyst size was calculated. Left hemisphere and middle cranial fossa location prevailed. A slight negative correlation of relative cyst size with age (r=−0.21, NS) disappeared when analysis was restricted to the adult age group (≥20 years). After the sample was divided into two groups according to relative cyst size (cysts less than mean volume vs cysts greater than mean volume), small AC showed no correlation with age, while large AC correlated positively with age (r=0.79,P〈0.05). A subgroup of large AC appears to expand with time, while the majority of small AC remain unchanged.
