Migraine pathophysiology involves a neuronal mechanism that is closely associated with the neuronal activation of peripheral trigeminal nociceptive pathways. It also involves a vascular mechanism that is supported by studies concerning the presence of migraine with aura in various vascular diseases. Migraine is associated with silent infarct-like lesions and white matter hyperintensities (WMHs) that can be encountered during magnetic resonance imaging. In this study, we aimed to demonstrate the migraine-WMH link based on pain lateralization. ⋯ Based on our study results, we concluded that pain in episodic migraine is associated with the occurrence of WMHs in the cerebral hemispheres.

Current sacroiliac joint (SIJ) cooled radiofrequency (RF) is based on fluoroscopic anatomy of lateral branches (LBs) in three specimens. Recent studies confirm significant variation in LB positions. ⋯ Using a conservative 8-mm lesion measurement, contemporary cooled RF needle targets are inadequate to lesion all target LBs. Modifications to current targets are recommended to increase the effectiveness of the procedure.
