Immune-checkpoint inhibitors (ICIs) have become one of the main strategies for advanced cancers. ICIs are associated with many immune side effects, called immune-related adverse events (irAEs). Since irAE has various variations, it is important to carefully examine each individual case that develops irAE. We experienced a case of polymyalgia rheumatica (PMR)-like irAE after three courses of administration of Ipilimumab and Nivolumab for stage IV lung adenocarcinoma. We also confirmed that the activity of this irAE was detectable on the PET-CT scan performed to assess lung cancer progression. Given the limited reports of PMR-like irAE occurring after treatment with two immune checkpoint inhibitors, we present this case along with a review of the literature.

: Immune checkpoint inhibitors (ICIs) transformed cancer treatment, producing significant survival benefits. However, ICIs can trigger toxicities called immune-related adverse events (irAEs), including inflammatory arthritis (IA) and polymyalgia rheumatica (PMR)-like syndromes. Our study aimed to systematically further characterize musculoskeletal ultrasound (MSKUS) findings in patients with ICI-IA and ICI-PMR, collectively referred to as "MSK-irAEs", and explore the role of US in guiding treatment.

Unlabelled: Immune checkpoint inhibitor (ICI)-induced arthritis is an increasingly recognized adverse event in patients with oncologic disease during immunotherapy. Four patterns are well described, including rheumatoid arthritis (RA)-like, polymyalgia rheumatica (PMR)-like, psoriatic arthritis (PsA)-like, and oligo-monoarthritis, among others. Despite better clinical recognition of these syndromes, information about the main imaging findings is limited.

Objective: To assess whether the polymyalgia rheumatica (PMR)-like syndrome reported as an immune related adverse event (irAE) from checkpoint inhibitor therapy is consistent with the 2012 European League Against Rheumatism (EULAR)/American College of Rheumatology (ACR) provisional criteria for PMR.
Methods: The cases were derived from two sources. Group 1 represents reported cases from three contributing centres.
