ABSTRACT
There are a few reports on tarsal tunnel syndrome resulting from the intraneural ganglion. Although it can occur through a connection with the adjacent joint, there is no consensus on its pathogenesis and treatment method. This paper reports a case of tarsal tunnel syndrome resulting from the intraneural ganglion of the medial plantar nerve of the tibial nerve.

Objective To evaluate the value of ultrasonography in diagnosing intraneural ganglion cysts . Methods The ultrasonographic images of 12 patients with intraneural ganglion cysts confirmed by surgery and pathology were retrospectively analyzed . The ultrasonographic features were summarized . Results The ultrasonographic images showed the location ,number ,size ,shape ,boundary ,internal echo , involvement extent and blood supply in intraneural ganglion cysts clearly . Intraneural ganglion cysts showed cystic masses within peripheral nerve ,boundary clear ,irregular-shaped ,ill-acoustic transmissibility ,and separations are common ,color Doppler examination showed no blood flow inside the cysts . Conclusions High frequency sonography is the preferred imaging method for diagnosis of intraneural ganglion cysts .
ABSTRACT
Intraneural ganglilon of superficial peroneal nerve was rare condition around foot and ankle. we experienced a case of recurred intraneural ganglion of superficial peroneal nerve on foot. We treated the case with idendify of intraarticular branch of ganglion. We report the case with a review of literature.

PURPOSE: Pathogenesis of intraneural ganglion is controversial, however, the synovial theory that the intraarticular region is the origination of disease has come into the spotlight nowadays. But there are a few researches about intraneural ganglion in foot and ankle. We studied 7cases of intraneural ganglion. We are going to prove the synovial theory by indentifying articular branch of intraneural ganglion. MATERIALS AND METHODS: From August 2003 to May 2011, we evaluated 7 ouf of 8 patients diagnosed as a intraneural ganglion in foot and ankle. The gender ratio were 4 male and 3 female, and the mean age at the time of surgery was 52.9 years. Clinically, we checked pre and post operative symptom, muscle tone and whether loss of muscle tone and sensation exists. We analyzed surgical records and preoperative MRI and compared those with intra-operative finding. RESULTS: In MRI analysis of 7cases, the connection around the joints were confirmed, and 1 case was confirmed in the retrospective analysis of MRI. Intraneural ganglions occurred in medial plantar nerve 3 cases, lateral plantar nerve 1 case, superficial peroneal nerve 1 case and sural nerve 1 case. We could not found recurrence during the follow up periods. Most patients relieved pain after operation, but recovery of sensation was unsatisfactory. We could find some cases pathological finding of the nerve intraoperatively, and clinical result of that cases was poor. CONCLUSION: Intraneural ganglion can occur in various parts in foot and ankle. We concluded that the intranneural ganglion originated from joint by identifying the artichlar branch of ganglion. Due to its small size, it is difficult to find articular branch in operation field. But we do our best to find and remove articular branch. Currently, considering the small amount of research in foot and ankle, more research about articular brach is needed.

Intraneural ganglia in the upper extremity are rare, and the involvement of the digital nerve of hand has not been reported. The following case report demonstrates a 57-year-old woman with a symptomatic nodular mass on the thenar area of the left hand. Magnetic resonance images showed a lobulated, homogeneous mass of high signal intensity on T2-weighted images and low signal intensity with peripheral enhancement on T1-weighted images. Excisional biopsy and histopathologic examination revealed an intraneural ganglion of the digital nerve of the thumb. Her symptom disappeared immediately after the surgery, and has remained free of abnormal sensation and parestheia for the 3-year follow-up period.

There are few reports on intraneural ganglion, and this malformations mainly occurs in peripheral nerves of the upper and lower extremities. In the lower extremity, it often occurs in the common peroneal nerve, with neurologic symptoms such as motor weakness and sensory changes. We experienced a case of intraneural ganglion of the common peroneal nerve around the fibular head and this was associated with neurologic symptoms, including weakness of the motor power in the ankle and great toe dorsiflexion and sensory change in the foot dorsum. It was successfully treated by complete excision. We report here on this unusual case and we review the relevant literature.

Cubital tunnel syndrome is a compressive neuropathy of the ulnar nerve posterior to the medial epicondyle of the elbow. The etiology is either idiopathic, or secondary to deformity, ectopic ossification, space occupying lesion, or osteophytes in elbow osteoarthritis. As a rare cause of cubital tunnel syndrome, we report an intraneural ganglion of ulnar nerve developed in proximal forearm with symptoms of ulnar neuropathy.

Intraneural ganglion is a relatively rare clinical entity that is commonly found in the peripheral nerves in the upper and lower extremities. It is commonly manifested by motor deficits, pain and sensory changes due to nerve entrapment and compression of the involved nerve. An intraneural ganglion of the tibial nerve is very rare. We present here a rare case of intraneural ganglion of the tibial nerve in the popliteal fossa and the patient had a neurologic deficit, and this was all treated successfully. We review the clinical course of the patient and the relevant issues are discussed together with a thorough review of the relevant literature.

Intraneural ganglion of the tibial nerve is very rare. We have experienced a case of the intraneural ganglion cyst in the tibial nerve and medial plantar nerve, which was located at the level of the ankle and foot. A 29-year-old male suffered from lumps causing numbness around the medial aspect of the sole and great toe. But there was no weakness and change of the motor function. We excised the cystic mass successfully and the neurologic symptoms disappeared.

An intraneural ganglion mainly affects the common peroneal nerve but the condition is relatively rare. Ganglions arising from the joint, tendon sheath or sheath of a peripheral nerve. We report three cases of intraneural ganglion cysts in the peroneal nerve that were treated by an excision.

To date, very few cases with intraneural ganglion cyst of the peroneal nerve has been reported. The common symptoms include localized pain and various degrees of motor and sensory deficits. Though electrodiagnostic study has been useful in lesion localization, recent imaging studies, such as ultrasonography and magnetic resonance imaging, should be used in establishing differential diagnosis and extent of a lesion preoperatively. Treatment can be achieved by microsurgical removal of the cyst. We had a 74 year old female with right foot drop for 3 months and we diagnosed that she had intraneural ganglion of the peroneal nerve using physical examination, electrodiagnostic study, ultrasonography, and magnetic resonance imaging. Although there was no specific symptom on the left side, there was a similar lesion like that of right intraneural ganglion, that was detected by ultrasonography. However, the patient's neurologic symptoms have not improved after operation.

Intrsneural ganglion cysts of the peroneal nerve are rare. The precise etiology and pathological changes remain obscure. We have experienced recently a case of intraneural ganglion cyst developed in the sheath of the peroneal nerve. A 28 year old male had suffered from lump producing pain over the posterolateral aspect of the upper portion of the fibula, weakness of dorsiflexion of the ankle and of extension of the toes and diminution of sensation on the dorsum of the foot. He underwent excision of the ganglion and the prognosis for recovery of function is good.
