Despite successful orthoptic liver transplantation some patients develop a recurrent headache that interferes with their quality of life.To estimate the frequency of this symptom 34 patients who had undergone orthoptic liver transplantation were questioned about the history and character of any headache.Six patients described a recurrent headache typical of migraine only since transplantation.In two patients the pain improved after reduction of cyclosporin dosage and thereby plasma cyclosporin concentration.newabs Ce13C At MR imaging,a non-enhancing mass in the cerebellar hemisphere was characterized by a striated pattern of hyperintensity on T2-weighted images and corresponding hypointensity on T1-weighted images,which represented the abnormally thickened folia.None of the masses demonstrated enhancement.Most other cerebellar masses destroy the folia pattern and show enhancement.The nonenhancing striated MR appearance of thickened folia in patients with LDD is distinctive and should suggest this diagnosis. |
