Fluorodeoxyglucose Positron Emission Tomography-Computerized Tomography Scan in LGI A1-Positive Limbic Encephalitis and Concordance with MRI in a Known Case of Carcinoma Breast.

The limbic encephalitis is an autoimmune disorder which characterized by inflammation of the brain with rapidly progressing dementia either due to paraneoplastic or nonparaneoplastic etiology which requires definitive neurological and whole-body evaluation. We describe both clinical and nuclear medicine imaging and radiological findings in a case of limbic encephalitis using positron emission tomography and magnetic resonance imaging.
