Cerebral Tumefactive Inflammatory Lesion Occurrence During Ixekizumab Treatment in a Patient With Active Psoriatic Arthritis.
Marangi et al., Neurologist 2024
DOI: 10.1097/NRL.0000000000000551
Summary of New Information:
A novel case of a cerebral inflammatory lesion was reported in a 72-year-old man following treatment with ixekizumab, an anti-IL-17A monoclonal antibody. This is significant as it is the first known instance of such a neurological complication associated with this medication, which is used for conditions like psoriasis and arthritis.
Importance:
The case highlights a rare but serious potential side effect of ixekizumab, suggesting that patients undergoing treatment with IL-17A inhibitors should be closely monitored for neurological symptoms.
Contribution to Literature:
This report contributes to the clinical understanding of ixekizumab’s safety profile by documenting an atypical adverse event. It underscores the importance of vigilance for central nervous system inflammatory manifestations in patients receiving IL-17A inhibitors, which have been previously considered uncommon.
Results:
The patient developed left face numbness one month after starting ixekizumab. MRI revealed a large brain lesion, which was not linked to infections or cancer upon biopsy. Treatment with dexamethasone led to clinical improvement and a near-complete resolution of the lesion on subsequent MRI.
