Computerized tomography (CT) of the head made at presentation at the emergency department (1 week after the ACDF) showed bilateral subacute subdural hematomas with a moderate midline shift (Fig. 1a, b). In retrospect, the preoperative MRI (magnetic resonance imaging) showed signs of a spinal longitudinal extradural CSF collection indicating a spinal leak (Fig. 1c, d).
