Paraneoplastic autoimmune encephalopathic syndromes have been described most often in association with small cell lung cancer or breast cancer, tumours of the ovaries, testes, lymphoma and thymoma. Antibodies associated with paraneoplastic encephalopathies are, among others, anti-Hu, anti-Ma2 and, in part, anti-N-methyl-D-aspartate(NMDA)-receptor antibodies. Here, we present the case of a 72-year-old patient hospitalised due to progressive cognitive decline and disorientation. Diagnostic workup revealed paraneoplastic anti-amphiphysin associated limbic encephalitis on the basis of an aortic angiosarcoma with metastases to kidney, muscle and bones. Highly aggressive chemotherapy as well as immunosuppressive therapy and cytoreductive laparoscopic nephrectomy were initiated. However, follow-up revealed further tumour progress and a worsening of neurological symptoms.
