1/9. tarsal tunnel syndrome: ultrasonographic and MRI features.tarsal tunnel syndrome is a well-known but rare entrapment neuropathy involving the posterior tibial nerve in the tarsal tunnel, a fibro-osseous channel extending from the medial aspect of the ankle to the midfoot. Posttraumatic fibrosis, ganglion cyst, tenosynovitis, tumor of the nerves or other structures, dilated or tortuous veins can cause significant nerve compression in this anatomic region. Herein, we present the typical ultrasonographic and magnetic resonance features of this disorder in patient with a ganglion cyst.- - - - - - - - - - ranking = 1keywords = ganglion (Clic here for more details about this article) |
2/9. tarsal tunnel syndrome caused by epineural ganglion of the posterior tibial nerve: report of 2 cases and review of the literature.ganglia within the posterior tibial nerve is a rare condition. The authors report 2 cases of epineural ganglion of the posterior tibial nerve, causing tarsal tunnel syndrome. Both cases presented with numbness on the plantar surface of the foot. magnetic resonance imaging showed the presence of the cyst within the tarsal tunnel. During surgery, these cysts were found within the epineurium of the posterior tibial nerve and were successfully removed without damage to nerve fibers. Both patients were free of symptoms after surgery. ganglion cysts in the peripheral nerve are either intrafascicular or epineural. Intrafascicular ganglia present beneath the epineurium and involve the nerve fibers, whereas epineural ganglia are located in the epineurium and do not involve the nerve fibers. A review of the literature discusses these concepts. The authors suggest that epineural ganglion should be clinically distinctive from an intrafascicular ganglion because of the differences in surgical treatment, postoperative nerve function, and the recurrence rate.- - - - - - - - - - ranking = 3.5keywords = ganglion (Clic here for more details about this article) |
3/9. tarsal tunnel syndrome caused by ganglion.We report a case of delayed diagnosis of tarsal tunnel syndrome caused by a ganglion arising from the talo-calcaneal joint. Unusually the symptoms were mainly due to the lateral planter nerve compression with a positive Tinel's sign. A surgical decompression was successful in relieving the dysaesthesia in spite of a 7 years history.- - - - - - - - - - ranking = 2.5keywords = ganglion (Clic here for more details about this article) |
4/9. Anterior tarsal tunnel syndrome.We have reviewed 10 patients treated for anterior tarsal tunnel syndrome produced by compression of the deep peroneal nerve or its branches, and we have studied the anatomy of the tunnel in 25 adult feet. The causes of onset of the syndrome included contusion of the dorsum of the foot, tight shoe laces, talonavicular osteophytosis, ganglion, and pes cavus. The clinical signs were often diagnostic but electromyography was helpful. Operative decompression in nine feet of eight patients gave successful results at 1.5 to 4 years follow-up.- - - - - - - - - - ranking = 0.5keywords = ganglion (Clic here for more details about this article) |
5/9. A ganglion causing the tarsal tunnel syndrome: report of a case.The tarsal tunnel syndrome is a complex of symptoms affecting the foot produced by compression neuropathy of the posterior tibial nerve on the medial aspect of the ankle, within the fibrous osseous "tunnel" that has the posteromedial aspect of the tibia as its floor and the flexor retinaculum as its roof. Keck first drew attention to this entity in 1962, and was followed by Lam in the same year. Despite sporadic reports following these documentations, the clinical recognition of the syndrome is often delayed. It is still frequently misdiagnosed as acute foot strain or plantar fasciitis at its initial presentation (Kopell and Thompson, 1963; Lam, 1962, 1967). In this paper we report a case of tarsal tunnel syndrome caused by compression of the posterior tibial nerve by a ganglion at the ankle.- - - - - - - - - - ranking = 2.5keywords = ganglion (Clic here for more details about this article) |
6/9. Benign cystic lesions of peripheral nerves.A patient with multiple cystic changes of the sural nerve, and another with a tarsal tunnel syndrome caused by invasion of the median plantar nerve by a ganglion in the tarsal tunnel, are presented. It is believed that there are three different kinds of benign cystic involvement of the peripheral nerves, multiple cystic degeneration of the nerve itself, invasion of nerves from outside by a ganglion and formation of simple cysts within the nerve proper, presumably as a result of trauma.- - - - - - - - - - ranking = 1keywords = ganglion (Clic here for more details about this article) |
7/9. The tarsal tunnel syndrome. Report of two cases of unusual cause.Since Keck described the tarsal tunnel syndrome (TTS) in 1962, it has been one of the most frequently diagnosed of the entrapment neuropathies. TTS is usually of unknown origin. This is a report of two unusual cases: TTS caused by neurilemmoma in a 33-year-old woman, and TTS caused by subperiosteal ganglion in a 14-year-old girl. The symptoms were relieved, in both instances, with surgical excision.- - - - - - - - - - ranking = 0.5keywords = ganglion (Clic here for more details about this article) |
8/9. tarsal tunnel syndrome with double causes (ganglion, tarsal coalition) evoked by ski boots. Case report.We report a 19-year-old female with tarsal tunnel syndrome arising from a ganglion and a bony prominence from talocalcaneal coalition. However, in this case, tarsal tunnel syndrome was caused by ski boots compressing the tibial nerve within the tarsal tunnel. The patient was successfully treated by surgery. This is believed to be the first case with double causes (ganglion, tarsal coalition) evoked by trauma (skiing).- - - - - - - - - - ranking = 3keywords = ganglion (Clic here for more details about this article) |
9/9. tarsal tunnel syndrome caused by strain of an anomalous muscle: an MRI-specific diagnosis.tarsal tunnel syndrome (TTS) is a compression neuropathy of the posterior tibial nerve in the ankle, commonly caused by a mass lesion such as ganglion, tumor, fracture, or post-traumatic fibrosis. Although anomalous muscle is relatively common in the ankle, there has been only one report to date implicating it in TTS. This case demonstrates MR findings of a strained flexor digitorum accessorius longus muscle as an unusual cause of TTS.- - - - - - - - - - ranking = 0.5keywords = ganglion (Clic here for more details about this article) |
