Cubital tunnel syndrome refers to compression neuropathy caused by pressure on the ulnar nerve pathway around the elbow. A 63-year-old male patient visited the clinic complaining of decreased sensation and weakness in his left ring finger and little finger, stating that the symptoms first began 6 months prior. He had undergone surgery to remove a ganglion cyst from his left elbow joint about 5 years prior in Mongolia. Magnetic resonance imaging revealed a cystic mass located at the previous surgical site, which was compressing the ulnar nerve within the cubital tunnel. Ulnar nerve decompression and anterior transposition were performed, and the cystic mass was excised. Upon pathological examination, the mass was diagnosed as a ganglion cyst. The patient's symptoms including sensory dysfunction and weakness improved over the 1-year follow-up period. This report describes a rare case of ganglion cyst recurrence compressing the ulnar nerve in the cubital tunnel after previous ganglion cyst excision.

Ulnar nerve compression in the cubital tunnel is a common entrapment syndrome of the upper limb. Pulsed radiofrequency lesioning (PRFL) has been reported as a treatment method for relieving neuropathic pain. Since the placement of the electrode in close proximity to a targeted nerve is very important for the success of PRFL, ultrasound seems to be well suited for this technique. A 36-year-old woman presented with complaints of numbness and pain on the medial aspect of the elbow and the pain radiated down to the $4^{th}$ and $5^{th}$ fingers for 10 years after she suffered an elbow contusion, we then scheduled this woman for the ultrasound guided PRFL of the ulanr nerve. The initial ultrasound examination demonstrated a swollen nerve, loss of the fascicular pattern and an increased cross sectional area of the ulnar nerve. After confirmation of the most swollen site of the nerve via ultrasound, two sessions of PRFL were performed. The postprocedural 10 cm visual analog scale score decreased from 8 to 1 after the two sessions of PRFL.

Ortner's syndrome is a rare clinical entity with hoarseness attributable to recurrent laryngeal nerve palsy in cardiovascular diseases. The mechanism of this condition is thought to be due to compression of the recurrent laryngeal nerve by a dilated, tense cardiovascular structure against its adjacent tissue; thus, this is also known as cardio-vocal syndrome. We experienced the case of a 81-year-old female suffering from hoarseness due to a large aneurysm of the aortic arch, and reviews the literature for possible cardiovascular causes of Ortner's syndrome.

Venous malformations arising from the peripheral nerve are a rare type of vascular malformation. We present the first case of an intraneural venous malformation of the median nerve to be reported in a child and review the previous two cases of median nerve compression due to a venous malformation that have been reported. These cases presented with painless masses in the volar aspect of the wrist or with symptoms suggestive of carpal tunnel syndrome. Clinical suspicion should lead to the use of Doppler ultrasonography as the first-line diagnostic tool. Magnetic resonance imaging and histopathology can confirm the diagnosis, as phleboliths are pathognomonic of venous malformations. Surgical treatment appears to be the only modality capable of successfully controlling the growth of an intraneural malformation. Sclerotherapy and radiotherapy have never been used to treat this type of malformation.

Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy caused by focal compression of the median nerve in the carpal tunnel. However, many patients with CTS, who are diagnosed clinically and confirmed with electrophysiological studies, complain of the sensory symptoms extends to the ulnar nerve territory. The aim of this study was to evaluate whether a dysfunction in sensory fibers of the ulnar nerve was present or not in hands with CTS patients who had extramedian spread of sensory symptoms over the hand. We retrospectively analyzed the recording of the subjects who were diagnosed with CTS within a one-year-period of time. After exclusions, 136 hands recordings of 87 patient were included. We compared the results of median and ulnar nerve sensory conduction studies between normal hands and hands with CTS. We did not detect statistically significant difference on all parameters of ulnar nerve sensory conduction studies between the normal hands and the hands with CTS. The parameters of the obtained in median nerve sensory conduction studies were statistically different between the healthy control and CTS patients. The hands with CTS showed similar rate of ulnar sensory conduction abnormalities compared with the normal hands. In conclusion, our study showed that none of the parameters in ulnar sensory nerve conduction studies differ between two groups. Accordingly, our study revealed that ulnar nerve involvement does not contribute in CTS patients underlying the spread of paresthesia extends to the ulnar nerve territory.

Tarsal tunnel syndrome is a complex of symptoms resulting from the compression of the posterior tibial nerve or its branches. Many studies have done on etiologic agents. We reported two cases of tarsal tunnel syndrome secondary to the varicosis of posterior tibial vein. Symptoms were relieved after excision of the varicosis, neurolysis and reposition of posterior tibial nerve.

Background : Carpal tunnel syndrome(CTS) is the most common entrapment neuropathy that refers to a group of signs and symptoms resulting from compression of the median nerve at the wrist. The course of CTS in older patients is different from the younger patients. This difference may be the result of different underlying mechanisms. The different nerve conduction studies of CTS may signify different approaches in management. This study was done to assess the differences in nerve conduction study of CTS in younger and older patients. Methods : This study involved 224 patients who visited Gachon Medical School, Gil Medical Center and was diagnosed by nerve conduction study from October 1997 to October 1999. We compared the results of nerve conduction study to age, especially in between those under 60 years and those 60 years or over CTS patients. Nerve conduction study consists of motor studies of both median nerves(terminal latency, compound action potential) and sensory studies(nerve conduction velocity, nerve action potential). And we also evaluated the variables between younger and older patients group. Those variables include sex, symptom period, laterality, abnormal physical findings and radiculopathy. Results : We found that a significant increase of terminal latency(p<0.1), but a decrease in compound motor action potential(p<0.05) in older patient's group. There was no significant differences in sensory nerve conduction velocity and action potential between those under 60 years and those 60 years or even patients. And also there was no significant difference in sex, symptom period, laterality, abnormal physical findings, radiculopathy between older and younger patients. Conclusions : This study showed a significant increase in the terminal latency and a decrease in compound action potential in older patients. The different nerve conduction studies of CTS by age effect may need different approaches in management.

Occipital neuralgia is a rare pain syndrome characterized by periodic lancinating pain involving the occipital nerve complex. We present a unique case of entrapment of the greater occipital nerve (GON) within the semispinalis capitis, which was thought to be the cause of occipital neuralgia. A 66-year-old woman with refractory left occipital neuralgia revealed an abnormally low-loop of the left posterior inferior cerebellar artery on the magnetic resonance imaging, suggesting possible vascular compression of the upper cervical roots. During exploration, however, the GON was found to be entrapped at the perforation site of the semispinalis capitis. There was no other compression of the GON or of C1 and C2 dorsal roots in their intracranial course. Postoperatively, the patient experienced almost complete relief of typical neuralgic pain. Although occipital neuralgia has been reported to occur by stretching of the GON by inferior oblique muscle or C1-C2 arthrosis, peripheral compression in the transmuscular course of the GON in the semispinalis capitis as a cause of refractory occipital neuralgia has not been reported and this should be considered when assessing surgical options for refractory occipital neuralgia.

Superficial peroneal nerve entrapment is an uncommon compression neuropathy, and is frequently associated with a fascial defect and a muscle hernia. The standard treatment of that was the nerve decompression by complete or limited fasciotomy. But, we experienced a case of superficial peroneal nerve entrapment had satisfactory surgical outcome by fascial repair of peroneus muscle.
