Figure 1. MRI of the Pseudomeningocele
MRI showing the giant pseudomeningocele measuring 17 cm in craniocaudal length and 9 cm in anteroposterior width shown in sagittal T2 (A) and in volume rendering (432 mL, C) caused by a dural tear (red arrow, axial T2, B) during a neurosurgical procedure.

Figure 2. Transcranial Doppler and EEG Recordings of the Paroxystic Episodes
Transcranial Doppler ultrasound of the left middle cerebral artery before, during, and after manual compression of the pseudomeningocele showing a decrease of intracerebral blood velocities with total disappearance of the diastolic signal during the compression (between the red and green arrows) (A). EEG recording before, during, and after clinical episodes provoked by lumbar pseudomeningocele compression (between the red and green arrows) showing a pattern of diffuse slowing, followed by attenuation typical of brain hypoperfusion (syncope) (B).
