“…It may be difficult to differentiate a ganglion cyst from nerve sheath tumors and also solid masses on Magnetic resonance imaging. Ganglia characteristically present with low signal on T1-weighted images and high signal on T2-weighted images [26]. Ultrasonography (US) may be effective in showing the cystic nature of the mass (well-circumscribed) and in differentiating it from solid tumors (anechoic lesion) [8] [9] [27]- [29].…”

Although ganglion cysts occur frequently, their presence in the lower extremities is rare and they seldom cause peripheral nerve compression. There are enumerable case reports of intraneural ganglion involvement with the common peroneal nerve and its branches, the sural nerve, and the posterior tibial nerve but extraneural ganglion sciatic and common peroneal nerve palsy cases are quite rare. Our case, a 26 years old female patient presented with right leg tingling and radiating pain followed up gradually with progressive right sided foot drop. MRI diagnosed the lesion as a ganglion cyst and the EMG/NCV confirmed the level of compression at the right fibular head. The patient was electively operated with standard lateral approach and the ganglion cyst engulfing the common peroneal nerve was excised. The cyst was traced to the base of its articular origin, excised and stalk ligated to prevent recurrence. At 1 year, there were no signs of recurrence and the patient was symptomatically free with no residual weakness. We, thus, report to you a rare cause of common peroneal nerve palsy-a proximal tibio-fibular joint "ganglion cyst"; a cause of foot drop which can be completely reversible if treated appropriately, its implications and thus, making its early diagnosis significant.

“…Rawal et al (20) hypothesized that the origin of peroneal nerve ganglia is the proximal tibiofibular joint, via the articular branch. Several papers report on local cyst recurrence postoperatively, and stress the importance of articular branch ligation to avoid this complication (21,24,(26)(27)(28). Simple excision of the ganglia is not sufficient.…”

RJ Greer-Bayramoglu, AS Nimigan, BS Gan. Compression neuropathy of the peroneal nerve secondary to a ganglion cyst. Can J Plast Surg 2008;16(3):181-183.Peripheral neuropathies caused by ganglion cysts are rare, particularly in the lower extremities. The case of a 45-year-old man with a twomonth history of foot drop and swelling in the region of the right fibular head is presented. Physical examination and electromyogram studies verified a peroneal nerve palsy. Magnetic resonance imaging revealed a lobulated, multilocular, cystic-appearing mass extending around the fibular neck. Surgical decompression of the nerve with removal of the mass and careful articular branch ligation was performed. Surgical pathology reports confirmed the diagnosis of a ganglion cyst. The patient regained full function within four months of the decompression. Pertinent findings on physical examination are discussed, as well as electromyogram and magnetic resonance imaging results. If symptoms persist, early surgical decompression (between the third and fourth months) is recommended.Key Words: Foot drop; Ganglion cyst; Peripheral neuropathy; Peroneal nerve compressions Neuropathie par compression du nerf péroné consécutive à un kyste ganglionnaire Les neuropathies périphériques causées par des kystes ganglionnaires sont rares, particulièrement au niveau des membres inférieurs. Les auteurs présentent ici le cas d'un homme de 45 ans présentant une chute du pied depuis deux mois et une enflure à la région de la tête du péroné. L'examen physique et l'électromyogramme ont confirmé une paralysie du nerf péroné. L'imagerie par résonance magnétique a révélé une masse d'aspect kystique lobulée et multiloculaire s'étendant autour du col du péroné. Une décompression chirurgicale du nerf avec ligature soigneuse du rameau articulaire ont été réalisées. Les rapports anatomopathologiques du spécimen reséqué ont confirmé le diagnostic de kyste ganglionnaire. Le patient a entièrement récupéré en l'espace de quatre mois suivant la décompression. Le présent article aborde les éléments pertinents de l'examen physique, de même que les résultats de l'électromyogramme et de l'imagerie par résonance magnétique. Si les symptômes persistent, une décompression chirurgicale précoce (entre le troisième et le quatrième mois) est recommandée.

✓The common peroneal nerve is the peripheral nerve most often affected by intraneural ganglion cysts. Although the pathogenesis of these cysts has been the subject of controversy in the literature, it is becoming increasingly evident that they are of articular origin. Recent recognition of this fact has proven to be significant in reducing recurrences and improving treatment outcomes for patients. The authors present a stepwise method of assessing and treating peroneal intraneural ganglion cysts.

MRI detection of cysts of the knee causing common peroneal neuropathy

Abstract: In 10 consecutive patients with footdrop due to common peroneal neuropathy without an obvious cause, MRI of the knee showed pathology at the fibular head in 6, including 5 patients with clinically unsuspected cysts of the tibiofibular joint. All 6 of the patients improved with surgery.
