Mr in suprascapular nerve entrapment caused by supraglenoid cyst compression
Main Article Content
Abstract
Suprascapular nerve entrapment has been regarded as a relatively uncommon condition that is easily overlooked in the differential diagnosis of shoulder discomfort. The common feature is nerve damage, caused either by trauma, extrinsic compression or by stretching secondary to repeated movements. Ganglion cysts account for the majority of the masses causing entrapment and seem to occur exclusively in men. Seven cases of suprascapular nerve entrapment caused by supraglenoid cyst compression were reviewed with MRI. MRI showed the cause and location of nerve compression as well as the distribution of muscular edema in all cases. MR imaging also allows an evaluation of the severity of the disease. It is also very efficient in excluding several differential diagnoses
