Spinoglenoid notch ganglion cyst
Updates to Article Attributes
Body
was changed:
Spinoglenoid notch ganglion cysts (SGNC's) are are form location specific ganglion cyst cysts that arise in the region of the spinoglenoid notch.
Epidemiology
They are generally rare can may be slightly commoner in males 2.
Associations
- labral tears of the shoulder: especially SLAP lesions 5.
Clinical presentation
They may result in compression of the suprascapular nerve at the spinoglenoid notch. Other descrbied features include infraspinatus atrophy, weakness with external rotation and posterior shoulder tenderness 4.
Radiographic features
MRI
Typically seen as a variably sized cystic lesion at the size of the spinoglenoid notch. signal characteristics are similar to other ganglion cysts and include
-
T1:
:low signal -
T2:
:high signal
MRI may also show associated infraspinatus atrophy.
Treatment and prognosis
Treatment option can vary ranging from conservative management to aspiration of the cysts to excision 4. Most cysts are thought to resolve with treatment 6.
Differential diagnosis
Imaging differential considerations include
- shoulder paralabral cyst extending into the spinoglenoid notch region.
- spinoglenoid notch varix 3
