Methods 6 patients with solitary FNH underwent MR exiamnation. Dynamic Gd-DTPA enhancement were performed in all the lesions. Of the 6 patients, three underwent CT plain and dynamic contrast scan; one underwent CT plain scan. More attention was payed to the atypical appearances. Results Atypical lesion appearances ineludod:apparent hypointensity on T1 WI and hyperintensity on T2WI,diffusly heterogeneous enhancement in arterial phase, pseudocapsule enhancement in delayed phase;the dynamic contrast MR and CT appearance in each phase were not all similar. Conclusion MR and CT especially dynamic contrast enhancemenl is of great value to the diagnosis of FNH. The atypical appearances of FNH shoud keep in mind to avoid misdiagnosis.
