Ultrasound-guided arthroscope insertion and decompression of a supraspinous fossa cyst.
A cyst arising in the scapular supraspinous fossa may cause shoulder pain; subsequently, enlargement of the cyst may result in severe compression of the adjacent suprascapular nerve, leading to muscle weakness and sensory disorder. Decompression of the nerve through cyst removal is effective in resolving these symptoms. However, treatment can also be performed less invasively through arthroscopy. Insertion of an arthroscope without visual guidance could cause tissue damage and, consequently, would become an invasive procedure itself. The use of ultrasonography to guide the scope to the cyst decreases the invasiveness of the procedure. Here, we present the case of a patient with a cyst arising in the scapular supraspinous fossa, in whom we could relatively readily and safely observe the cyst by advancing an arthroscope under ultrasonographic guidance. The suprascapular nerve was decompressed via cyst removal.
