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.
作者展示了19例脑淋巴瘤患者（包括12例原发性肿瘤）的CT研究结果。CT表现差异很大，因为12例原发性淋巴瘤中有5例表现为多灶性病变，病变部位包括胼胝体（3例）、尾状核中部（4例）、后颅窝（3例）和大脑半球（6例）。这些发现与文献数据一致。虽然胼胝体或尾状核中部出现孤立、高密度且均匀的病变提示脑淋巴瘤，但还有许多其他表现也是可能的，鉴于这种病理情况的发生率不断增加，应考虑这一诊断。继发性淋巴瘤没有特异性表现，但合并全身受累时通常有助于诊断。
