Case 3. A, The left peroneal nerve was decompressed and noted to contain an intraneural ganglion cyst. The articular branch (vessel loop) to the superior tibiofibular joint was dissected and found to contain cyst fluid. B, The cyst decompression was begun proximally, with return of cyst fluid (dotted circle). The cyst was noted to be continuous with the intraneural fluid of the articular branch distally (vessel loop). C, The course of the cyst was decompressed distally through the terminal segment of the articular branch. D, The articular branch was transected distally at its insertion, and the distal transected end (asterisk) was reflected laterally into the peroneus musculature.
