Compound Ganglion

Large effusions into the sheath of the flexor tendons of the wrist, usually purulent or tuberculous in character, sometimes cause two swellings, one in the palm of the hand and the other above the wrist. These communicate beneath the anterior annular ligament and form what is called a compound ganglion (Fig. 352).
