A 14-year-old male patient (known case of Wegener’s granulomatosis) was admitted to ER with multiple generalised tonic-clonic convulsions and loss of consciousness. Upon admission, patient’s blood pressure was 170/90 mmHg with a heart rate of 90/min and bilateral crepitations on auscultation in the chest (SpO2 of 90% on room air). Non-contrast computed tomography (CT) scan of the head showed bilateral symmetrical hypodensities in white matter and cortical areas of the parietal and occipital regions suggestive of PRES [Figure 1]. Blood investigations showed mild anaemia, leucocytosis, increased serum creatinine (4.9 mg/dl) and hyperkalaemia (5.8 mEq/l).
