Abstract

Introduction: Neurofibromatosis type-1 is a genetically transmitted neuro cutaneous syndrome. ADC technique is one of the accepted diagnostic techniques in understanding the microstructural anomalies of the NF-1 disease. In this study, our aim was to evaluate the lesions of NF-1 diagnosed child patients, who underwent to brain MRI, with the use of the ADC valued imaging technique. Material and Method: Diffusion weighted images and conventional sequences of children, who have been monitored with NF-1 diagnosis in our clinic and underwent brain MRI between 2010 January and 2015 June, were evaluated. Totally 89 lesions of 53 patients (21 women, 32 men), (age: 9,75±4.05) were investigated. 24 healthy volunteers were also added to the study. Lesions were investigated by dividing into four groups according to their locations and the mean ADC value was measured for each group. The locations of the lesions were determined as dentate nucleus, thalamus, basal ganglions and brain stem. Results: The number of the lesions were 32 in the dentate nucleus, 34 in the basal ganglion level, 10 in the brain stem and 13 in the thalamus. The mean ADC values of undefined bright objects (UBOs) located at the dentate nucleus, thalamus, basal ganglions and brain stem were higher than the control group. The ones with the highest ADC values were in the basal ganglion level, and the ones with the lowest ADC values were in the thalamus. The lesions with the highest lesion diameter were in the thalamus (9,17 ±0,47mm) and the smallest ones were in the brainstem (6.5±0.56mm). There was a statistically significant difference between the ADC values of UBOs located at the supra (n=47) and infratentorial (n=42) regions. Discussion: Determination of the mean ADC values according to the localizations will contribute to other studies which will done with diffusion technique.in NF-1 patients.

Özet

Giri ş N ö rofibromatozis tip -1 genetik ge ç iş g ö steren n ö rokutan ö z bir sendromdur. ADC tekniği ise NF-1 hastalığındaki mikroyapısal anormalliklerin anlaşılmasında kabul edilen tanı y ö ntemlerindendir. Bu ç alışmada amacımız NF-1 tanısı ile beyin MRG ç ekilen ç ocuk hastalardaki lezyonların ADC ağırlıklı görüntüleme tekniği ile değerlendirilmesi Materyal-method: Klini ğimize Ocak 2010–Haziran 2015 tarihleri arasında NF-1 tanısı ile takip edilen ve beyin MRI çekilen ç ocuk hastaları n dif üzyon ağırlıklı g ö rüntüleri ve konvansiyonel sekansları değerlendirilmiştir. Çalışmada 53 adet hastanın (21 kadın, 32 erkek), (yaş: 9,75±4.05) 89 adet lezyonu incelenmiştir. 24 adet sağlıklı bireyin beyin MR si incelenerek kontrol grubu oluşturulmuştur. Lezyonlar lokalizasyonlarına g ö re d ö rt gruba ayrılarak incelenmiş olup her bir grup i ç in mean ADC değerleri ö lçülmüştür. Lezyon lokalizasyonları dentat nükleus, talamus, bazal ganglion, beyin sapı olarak belirlenmiştir. Bulgular: Lezyon sayısı dentat nukleusta 32, bazal ganglion düzeyinde 34, beyin sapı i ç in 10 adet, talamus i ç in 13 adettir. Dentat nü kleus, talamus, bazal ganglion, beyin sapı UBO’ (undefined bright object) lardaki ADC değerleri kontrol grubu ile kıyaslandığında belirgin olarak yüksek bulunmuştur. ADC değerleri en yüksek olanlar bazal ganglianlar düzeyinde iken, en düşük olanlar talamus lokalizasyondadır. Lezyon ç apı en büyük olanlar talamusta iken (9,17 ± 0,47 mm) en k üçük olanlar beyin sapı düzeyinde (6.5± 0.56 mm) dir. Supra (n=47) ve infratentoriyal (n=42) UBO’ların ADC değerleri arasında istatistiksel olarak belirgin bir fark bulunmaktadır. Tart ış ma: N F-1 hastalarının mean ADC değerlerinin lokalizasyonlara g ö re de ğerlerinin belirlenmesi difüzyon tekniği ile yapılacak diğer ç alışmalara da katkıda bulunacaktır.
