[Tomodensitometric aspects of brain lymphomas: apropos of 19 cases. Brain lymphoma].
The authors present the results of CT studies for 19 patients with cerebral lymphoma (including 12 primary tumors). CT appearances varied considerably, because 5 of the 12 primary lymphomas presented as multifocal lesions, and lesion sites included the corpus callosum (3 cases), the central caudate nucleus (4 cases), the posterior fossa (3 cases), and the cerebral hemispheres (6 cases). These findings are in agreement with literature data. Although a solitary, hyperdense and homogeneous lesion in the corpus callosum or the central caudate nucleus is indicative of cerebral lymphoma, numerous other aspects are possible and owing to the increasing frequency of this pathology should suggest this diagnosis. There is no specific appearance for secondary lymphomas, but diagnosis is often facilitated by concomitant systemic involvement.
