MR spectroscopy in pediatric Wernicke encephalopathy.
The patient is a 7-year-old girl with a history of repaired gastroschisis and short gut syndrome. She presented with a 4-day history of progressive encephalopathy, truncal ataxia, and omnidirectional gaze-evoked nystagmus. Peripheral lactate was 7.1 mmol/L. Serum thiamine level was decreased (,5 nmol/L). Brain magnetic resonance with spectroscopy is shown in the figure. A clinical diagnosis of ...
متن کاملProton MR spectroscopy in Wernicke encephalopathy.
Wernicke encephalopathy is caused by thiamine deficiency. Although the clinical picture has been well established for some time, clinical diagnosis is attained in only 20% of the cases. MR imaging techniques contribute to early diagnosis of Wernicke encephalopathy. We herein report MR imaging and proton MR spectroscopic findings for a patient with clinical and biochemical features consistent wi...
متن کاملProton MR spectroscopy of Wernicke encephalopathy.
Two patients with acute thiamine deficiency were examined with thalamic single-voxel proton MR spectroscopy. T2-weighted images exhibited increased signal intensity. N-acetylaspartate (NAA)/creatine (Cr) ratios were low without detectable lactate. Owing to substantially decreased choline (Cho) T2, the Cho/Cr ratio was not decreased. After thiamine therapy, the NAA/Cr ratio increased, parallelin...
متن کاملWernicke encephalopathy: MR findings in five patients.
Wernicke encephalopathy is a disease usually related to chronic alcoholism. The clinical diagnosis is often difficult to establish, and CT is unable to provide specific findings. MR follow-up studies in five patients affected by Wernicke encephalopathy were performed with the aim of establishing the sensitivity of MR in depicting the typical diencephalic/mesencephalic lesions. All subjects had ...
متن کاملGadolinium-enhanced MR findings in a pediatric case of Wernicke encephalopathy.
This report describes the postcontrast MR findings of Wernicke encephalopathy seen in a malnourished 11-year-old boy. The examination showed increased signal on T2-weighted images in the periaqueductal gray matter and medial thalami. On T1-weighted acquisition, these areas showed decreased signal intensity, but on postcontrast T1-weighted examination, they showed moderately intense enhancement....
