Diffuse large B-cell lymphoma with cord compression. MRI prior to lumbar puncture and intrathecal chemotherapy.. There are multiple small enhancing lesions throughout the calvarium compatible with metastases. No intracranial mass or mass-effect is seen. No abnormal parenchymal or meningeal enhancement is seen. No restricted diffusion to suggest acute ischemia. No intracranial hemorrhage. The ventricles are within normal limits in size and configuration. Several foci of T2/FLAIR hyperintensity are seen in the bilateral subcortical and periventricular white matter, which are nonspecific, but compatible with mild chronic small vessel ischemic changes. Brain parenchyma is otherwise unremarkable for age. Major flow-voids are preservedSella and orbits are grossly within normal limits. Mild mucosal thickening in the paranasal sinuses with small right maxillary mucous retention cyst. Mastoid air cells are clear.
1. No intracranial mass or mass effect to contraindicate lumbar puncture.2. Multiple small enhancing lesions throughout the calvarium consistent with osseous metastases.
