Headache. Rule out bleed/mass. Areas of high-density line the ependyma of the frontal horns of the lateral ventricles bilaterally with associated edema that crosses the corpus callosum. The lateral ventricles appear enlarged while the third and fourth ventricle are normal in appearance indicating mass effect at the level of the foramen of Monro. There is prominence of the pineal gland. These findings are highly suspicious for lymphoma. A germ cell tumor is in the differential but less likely. An MRI is recommended for further evaluation.The calvaria and skull base are radiographically normal. The visualized paranasal sinuses and mastoid air cells are normally pneumatized.These findings were discussed with Dr. Glickman at the time of interpretation.
