Plexiform neurofibromatosis and the "Target sign" on MRI

Nöral kaynaklı yumuşak doku tümörleri, T2-ağırhklı MR görüntülerinde santrali hipointens çevresi hiperintens hedefe benzer yuvarlak lezyonlar oluşturabilir. T2-ağırlıklı MR görüntülerinde izlenen "hedef paterni", nörofibromaların malign periferal sinir kılıfı tümörlerinden ayrılmasında, yardımcıdır. Bu çalışmada alt ekstremite yerleşimli pleksiform nörofibromatozisli beş yaşındaki bir çocuk sunulmuş ve MR incelemesindeki "hedef paterni" tartışılmıştır

Pleksiform nörofibromatozis ve MRI'da "Hedef paterni"

T2-weighted MR imaging (MRI) of soft tissue tumors of neural origin may show round lesions with a central hypointensity and a hyperintense rim resembling a target. This "target sign" on T2-weighted MR imaging is helpful in differentiating neurofibromas from malignant peripheral nerve sheath tumors. Here, we report a five-year-old boy with lower limb plexiform neurofibromatosis and discuss the "target sign " on MRI.
