Entrapment neuropathy of the inferior branch of the suprascapular nerve by ganglia.
In a 37-year-old man, bilateral infraspinatus muscle weakness was associated with compression of the suprascapular nerve. The compression occurred at the spinoscapular angle by bilateral development of ganglia. The lesion was confirmed by electromyography. Surgical approaches to the area are described along with a review of the literature on different diagnosis. Complete recovery of neurologic function was documented.
