Ganglion as cause of triggering of fingers have been described previously but they are not commonly described for the Thumb. We present the case of a 34-year-old lady who presented with triggering of the right thumb of few months duration. Patient chose to decline further imaging work up or injections. She elected to proceed with surgery. Surgical exploration revealed a 4x2mm ganglion in the A-1 pulley which was excised and resulted in complete resolution of the symptoms. To the best of our knowledge this is only the second described case report in English Literature.
