Benign clear-cell tumor ("sugar" tumor) of the lung: a case report and review of the literature.

abstract：:Two patients with a total of 4 intracerebral hemorrhages were examined by serial computer tomography (CT) over a period of up to 6 months, revealing a progressive decrease in lesion volume and density which eventually became less than that of the surrounding brain tissue. These changes were interpreted as complete clo...
