case_images: Cerebral magnetic resonance imaging (cMRI) showing an isolated uncomplicated developmental venous anomaly in the right temporal lobe (white arrow) on the contrast enhanced initial axial MPRAGE (A) and on the 2 year follow-up epilepsy specific high-resolution T2-weighted axial reformatted 3D-FLAIR (B) and coronal T2-weighted STIR (C) images. cMRI scans were acquired on a Siemens 3T scanner TRIO (A) and PRISMA (B,C).

case_images: The initial contrast-enhanced cerebral magnetic resonance imaging (cMRI) as well as the 2-year follow-up epilepsy-specific cMRI including high-resolution 2D- and isotropic 3D-MRI-sequences showed an isolated and uncomplicated developmental venous anomaly (DVA) in the right temporal lobe (Figure 1).
case_images: Ictal EEG recording during long-term video-EEG monitoring: Generalized spike-wave complex with fronto-central maximum associated with a habitual myoclonic jerk of the right hand during writing. Longitudinal bipolar montage, 50 Hz notch filter, low-pass filter 30 Hz, high-pass filter 1 Hz.

case_images: The monitoring was performed over 5 days and, during this period, the patient showed over 100 myoclonic jerks of the upper limbs (right, left, and bilaterally synchronous), frequently associated with generalized spike-wave complexes (Figure 2) and occasionally with left or right accentuation.
