Abstract

A woman in her 60s developed acute onset headache, blurry vision and encephalopathy a few hours after rituximab infusion, given to treat granulomatosis with polyangiitis. CT scan showed oedema in the posterior circulation area suggesting the diagnosis of posterior reversible encephalopathy syndrome, and an MRI confirmed it. After being treated with aggressive blood pressure control and other supportive measures, her symptoms improved over 3–4 days. This case highlights the need for awareness and early recognition of this rare but serious adverse effect of rituximab. CT scan can be helpful in diagnosis (also to rule out bleeding), but the MRI provides the most accurate diagnosis.
