Tolosa-Hunt syndrome (THS) is a rare neurological disorder characterized by painful ophthalmoplegia due to idiopathic granulomatous inflammation of the cavernous sinus or orbital apex. This review aims to summarize recent advances in the etiology, diagnosis, and management of THS.

The etiology of neuralgia amyotrophy remains unclear. Herpes zoster induced neuralgia amyotrphy has been reported in extremely rare cases. In this case report, we describe the clinical features and electrophysiologic findings in a 68-years-old patient with neuralgia amyotrophy associated with herpes zoster infection. We suggest that brachial plexus inflammation due to viral infection may be a direct cause of reversible neuralgia amyotrophy.
