Lipoma brain tumor
Lipomas are benign fatty growths that can be found virtually anywhere in the body. They generally do not change much in size over time. If they are not causing a problem they will usually be left alone. A lipoma specifically in the brain may or may not be a problem. If in the corpus callosum, depending on size and location, it could conceivably cause hydrocephalus. Furthermore, if large, it could cause a deficit simply via mass effect. An MRI would be instrumental for evaluating this type of condition. Lipomas do not necessarily need to be treated. Only when they cause problems referable to their size and location do lipomas require intervention.
