Probable cerebral amyloid angiopathy-related inflammation presenting with dissociated hemorrhagic and inflammatory lesions in a middle-aged patient: A case report.

This case highlights probable CAA-ri in a middle-aged adult, presenting with subcortical hemorrhage and spatially dissociated inflammatory lesions. Despite the subtle inflammatory findings, clinical, imaging, and histological evaluations supported the diagnosis. Early recognition and immunosuppressive therapy can achieve favorable outcomes, emphasizing CAA-ri's inclusion in the differential diagnosis of lobar hemorrhage in relatively younger patients without hypertension or vascular risk factors.
