[Imaging of nodular regenerative hyperplasia of the liver. Study of 9 cases].

Radiologic patterns of the liver in nodular regenerative hyperplasia are poorly known. The authors describe the features of the liver observed during ultrasonography, angiography, computed tomography and magnetic resonance imaging in 9 patients with nodular regenerative hyperplasia. Generally the liver appeared normal, occasionally with signs of portal hypertension. However, a pseudotumoral pattern was observed in 2 patients: they had well limited hypoechoic lesions on ultrasonography, and in one patient angiography showed hypervascularity.
