Magnetic resonance neurography of peripheral nerve following experimental crush injury, and correlation with functional deficit.
In a number of clinical studies magnetic resonance (MR) neurography has been used to examine patients with peripheral nerve damage, but little is understood about the sequence of imaging changes following nerve injuries, and how they correlate with functional deficit. The goal of this study was to further understanding of these changes and their implications. ⋯ In this study the authors demonstrate that quantitative assessment of nerve signals with MR neurography allows the sequence of events following nerve crush injury to be followed in vivo, and that a return toward a normal signal correlates with functional improvement. Assessment of peripheral nerve injury in patients by using MR neurography has the potential to confirm acute nerve injury as well as to monitor the recovery process.

Case ReportsBilateral cavernous sinus actinomycosis resulting in painful ophthalmoplegia. Case report.
The authors report the successful treatment of a 42-year-old man who suffered from recurrent painful ophthalmoplegia caused by bilateral cavernous sinus (CS) actinomycosis. A presumptive diagnosis of Tolosa-Hunt syndrome was made when he presented with left painful ophthalmoplegia. ⋯ Actinomycosis may present as a painful ophthalmoplegia with involvement of one or both CSs. Repeated imaging and possibly surgical exploration may be necessary to make a definitive diagnosis.
