ABSTRACT Introduction Amyloid related imaging abnormalities effusion/edema (ARIA‐E) is seen in patients treated with antiamyloid antibodies. It resembles cerebral amyloid angiopathy (CAA) related inflammation (CAA‐ri) caused by an inflammatory response to amyloid deposition in the walls of cortical and leptomeningeal vessels in patients with sporadic CAA. Recently, temporary inflammatory imaging findings that remained clinically silent have been described in patients with iatrogenic CAA (iCAA). Results We describe a case of probable iatrogenic CAA (iCAA), which demonstrated radiological features of CAA‐ri that remained clinically silent and spontaneously resolved before the inaugural intracranial hemorrhage. Clinical and radiological features resembled ARIA‐E. Discussion This case adds to the clinical and radiological spectrum of iCAA and suggests an immune‐mediated response to amyloid deposition.
