Combined hepatocellular and cholangiocarcinoma: correlation between CT findings and clinicopathological features.

abstract：:Neuroradiological findings in two cases of histologically confirmed intracranial sarcoidosis are presented, one with periaqueductal granulomata causing aqueduct obstruction. The granulomatous aggregation was of slightly greater attenuation than normal brain parenchyma and did enhance homogeneously following contrast m...
