Abstract

Immune-related adverse events (irAEs) are a frequent complication of immunotherapy, but neurological irAEs are rare and varied. Here, we present a case of cerebral amyloid angiopathy-related inflammation (CAA-ri) attributable to nivolumab monotherapy, which has not been previously reported. The context of immunotherapy and availability of serial imaging also provide unique insights into the pathogenesis and evolution of CAA-ri. Routine surveillance neuroimaging in a patient with metastatic melanoma, in remission after treatment with nivolumab, demonstrated progressive microhaemorrhages and associated oedema, suspicious for CAA-ri. These changes progressed despite cessation of nivolumab. The ..
