Capgras syndrome and confabulation unfurling anti NMDAR encephalitis with classical papillary thyroid carcinoma: First reported case
Abstract
Anti NMDA Receptor encephalitis (ANMDARE) is an immune mediated disease of the central nervous system, caused by circulating antibodies against the NMDA receptor present on neuronal surface. It is known to cause a spectrum of disease ranging from mild behavioral and psychiatric manifestations to full blown seizures, dyskinesias and altered sensorium. It can also be paraneoplastic presentation of a hidden tumor, most commonly ovarian teratoma. Here we present a case of ANMDARE with intriguing presentation of Capgras syndrome and confabulations, who was found to have a malignant papillary thyroid carcinoma, which has been rarely reported.
