Description	A rare acquired non-paraneoplastic limbic encephalitis disorder, that develops in the setting of treatment-related immunosuppression, typically after allogeneic haemapoietic stem cell transplantation. Characterised by onset of confusion, headache, anterograde amnesia, seizures and/or loss of consciousness 2-6 weeks following transplantation. Bilateral, non-enhancing T2 hyperintensities in limbic structures are observed on magnetic resonance imaging. Mild cerebrospinal fluid pleocytosis and syndrome of inappropriate antidiuretic hormone secretion may also be associated.
