Among the various reasons that can cause entrapment of suprascapular nerve, suprascapular cyst is not commonly found and more often, overlooked or misdiagnosed. Authors experienced one case of suprascapular cyst causing suprascapular nerve entrapment confirmed by ultrasonography and MRI. Symptom of the patient was confined to infrascapular nerve. Percutaneous aspiration of cyst was done under the guidance of ultrasonography through Neviaser portal on out-patient department. After 8 weeks of follow-up, no recurrent lesion was found and objective functional improvement was identified. When clinicians confront with the symptoms compatible with suprascapular nerve entrapment, every effort should be put on finding lesion under ultrasonography before attempting any further cost-ineffective or time-wasting evaluation. Symptoms caused by space-occupying cyst will be soothed by simple decompression. However, always be aware of concomitant lesions that might be the reason for the cystic lesion and in some cases, further evaluation is inevitable.

Spinoglenoid cyst have been reported in small series in the orthopaedic literature in association with SLAP lesion, which is one of less common causes of shoulder pain. Authors experienced one case of spinoglenoid cyst with SLAP lesion initially missed with ultrasonographic examination and physical examination. This case was confirmed by MRI, EMG and arthroscopic surgery was done. When clinicians cannot find a definite cause of shoulder pain and decreased power of rotator cuff tendon with ultrasonographic examination, they need further study such as MRI and EMG with careful physical examination. Clinicians need to aware of the limitation of ultrasonography for spinoglenoid cyst especially, (1) cyst size is small, (2) location of cyst is too deep to detect and along the scapula spine from SLAP lesion.
