CT of renal lymphoma in children.

Objective: The purpose of this study was to determine the incidence and to describe the CT findings of renal lymphoma in children.

Conclusion: Renal lymphoma was seen in 11 children, most commonly due to non-Hodgkin's lymphoma (n = 10, 91%) and Burkitt's subtype (n = 5, 45%). Multiple bilateral masses were the most common CT appearance.

Xanthoma disseminatum: a rare intracranial mass.

We report the CT, MR imaging, and histologic findings in a patient with an intracranial mass diagnosed as xanthoma disseminatum (XD). The mass demonstrated radiographic findings typical for a glioma. However, histologic examination of brain and dermal lesions showed findings characteristic of XD.

Diffusion anisotropy in the corpus callosum.

Background And Purpose: The corpus callosum is a heterogeneous white-matter tract that connects the cerebral hemispheres. The purpose of this investigation was to study its microstructural architecture in normal human adult brains by using diffusion tensor imaging (DTI).

Methods: Two hundred consecutive patients referred for brain MR imaging underwent additional DTI with a high gradient field strength applied in six directions.
