![]() This infection can be diagnosed with an LP, and the presence of TB elsewhere in the body can help your healthcare providers determine whether lesions on your meninges or in your brain could be caused by the infection as well. Tuberculosis (TB) meningitis/ TB encephalitis: An uncommon infection that appears as spots on a brain imaging test, the lesions of TB meningitis tend to be smaller and greater in number than lesions of a brain tumor.Encephalitis: Inflammation of the brain that can be caused by an infection or an autoimmune disease, encephalitis causes a variety of symptoms depending on the region of the brain that is affected.Usually, repeating imaging studies can help differentiate an abscess from a brain tumor, but sometimes an abscess is diagnosed with a biopsy. These infections tend to be quite rare, but they can be mistaken for brain tumors due to their symptoms and appearance on imaging tests. Depending on the circumstances, a person may have one or more abscesses in the brain. Brain abscess: An abscess is an enclosed area of infection.Gliomas tend to be highly aggressive tumors, requiring intense treatment. Glioma: A primary brain tumor that arises from glial cells, which are supportive nerve cells in the brain, a glioma can begin on the optic nerve, the brainstem, or the cerebral cortex.As with other brain tumors, a pituitary tumor can be visualized on brain imaging studies, and unlike other brain tumors, it can produce hormonal changes that can have a wide-ranging impact on the body. Pituitary tumor: Another primary brain tumor that can be either completely treatable or very aggressive, a pituitary tumor is cancer of the pituitary gland, a structure in the brain that controls hormones.Depending on the grade of a meningioma, which is determined with a biopsy, it may have a good prognosis if it is completely removed surgically, or there may be a chance of recurrence or invasion of the brain. Meningioma is among the most common types of brain tumors. Meningioma: This is a primary brain tumor that grows from the meninges, the protective tissue that surrounds the brain, and not actually from the brain itself.Generally, a metastatic tumor is a highly aggressive tumor that might not improve with treatment. Metastatic brain tumor: A metastatic tumor in the brain is one that started somewhere outside the brain, such as the breast, lungs, or colon, and spread to the brain.It may grow, spread, or stay in one small spot, depending on which type of brain cell the primary brain tumor originally started from. Primary brain tumor: A primary brain tumor is a tumor that started in the brain.CBTRUS statistical report: primary brain and other central nervous system tumors diagnosed in the United States in 2014–2018.

A PET scan can differentiate between a growing tumor and inflammation.Īmerican Association of Neurological Surgeries. Malignant tumor cells appear brighter in the images because they absorb more glucose. The PET scanner rotates around your body and produces a picture of where glucose is being used in your brain. ![]()
