Results: MR demonstrated capsule wall and papillary solid lesions in one case with cystic and solid lesions of hepatobiliary cystadenoma. Poly cystic form tan if different sine in sew case, capsule wall and septation was thick, part of capsule wall was obviously thickened and nodes form, intrahepatic bile duct was dilated, large poly-antrum cystic keen form structure in one case, capsule wall and septation were smooth, part of capsule wall was uniformly thicken, capsule wall, septation, mural nodus form and solid lesions in three cases wee all slightly hyperintense on T2WI and slightly hypointense on T1WI. Part of cyst fluid was hypointense on T2WI the diameter if tumor ranged from 3.4cm to 13.5cm. Part of capsule wall, septation, solid lesions and mural nodus west obviously enhanced in arterial phase in three cases, the extent of enhancement showed a little degrade in port vein phase, balance phase and delay phase, but dense to liver parenchyma at synchronization.

Of 11 cases of edema had diffusive uneven SCC lesions. 1 case of edema had single midline oval lesion of splenium. The brain lesions of edema were incontinuous. In follow-up MRI of 5 cases of brain edema, the lesions were disappeared. In 3 cases of cerebral infarct, the lesions of SCC and brain were lateral distribution. 2 cases of hemorrhagic disease had diffusive uneven lesions in SCC and ventricle.

Of the 26 lesions with pontine and bulbar involvement, three had no association with other lesions (Fig 2). Twelve were associated with tegmental and superior cerebellar peduncular extension, and six showed corticospinal tract involvement in continuity with an MDJ lesion. In one patient with additional telencephalic lesions, the right side of the pons was hyperintense on long TR/TE images that did not cross the midline, suggestive of an arterial lesion (Fig 3). In two patients with pontine tegmental lesions, there was an associated middle cerebellar peduncle and deep cerebellar white matter involvement (Fig 4). Two others had associated cervical lesions.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides.
