In post-stroke patients, the pain or paresthesia of the affected limb is common. These symptoms may be caused by a variety of pathologic conditions. Considering the debilitating effects of the pain, it is important to determine the exact cause and manage appropriately. A 41-year-old woman who had experienced a hemorrhagic lesion in the right basal ganglia and corona radiata 4 months previously presented with an irritating tingling sensation in her left upper extremity. She failed to respond to a number of treatment options including medications and physical agent modalities. Following a diagnosis of disputed thoracic outlet syndrome (TOS) caused by scalene muscle dysfunctions, she received ultrasound-guided electrical twitch-obtaining intramuscular stimulation (ETOIMS) which significantly alleviated the pain. This case suggests that the disputed TOS should be considered as one of the possible causes of post-stroke pain, and that detailed history-taking and physical examination, as well as imaging or electrophysiological studies, might be required for accurate diagnosis. Furthermore, ultrasound-guided ETOIMS can be used as a safe and minimally invasive technique for the treatment of the disputed TOS with fewer systemic and local side effects.

A 33-year-old woman presented with tingling and paresthesia on left extremity for 2 months. Magnetic resonance imaging revealed that the tumor was iso- and hypo-intensity on T1-weighted image, mixed iso- and high-signal intensity on T2-weighted images and heterogeneously enhanced with rim enhancement. Neither arachnoid cleft nor dural tail was certain but mass was located extra-axially so meningioma was suspected. During operation, tumor wasn't attached to dura at all but arachnoid attachment was seen. Pathologically, clear cell type ependymoma was confirmed. Details of diagnosis and treatment of this tumor is described.

A 55-year-old male presented with dysesthesia of the right anteromedial thigh. A magnetic resonance image revealed a globular mass at the right extraforaminal area of the L3/4 level. Based on the diagnosis of neurogenic tumor, surgical excision was performed. The surgical impression and pathology confirmed extrusion of intervertebral disc. In a retrospective review of the magnetic resonance image, we noticed a fibrillary pattern directed from the intervertebral disc space to the lesion, and disrupted annulus fibrosus and indentation caused by the ring apophysis. We suggest aforementioned features, indicative of intervertebral disc lesions, to be checked when interpreting mass lesions around the intervertebral foramen.

Microscopic polyangiitis (MPA) is a systemic small vessel vasculitis with few or no immune deposits and no granulomatous inflammation. Peripheral neuropathy occurs in approximately 20%–30% of patients with MPA. We report a case of a 66-year-old woman who presented with paresthesia and motor weakness of the extremities and rapidly progressive glomerulonephritis. She was later diagnosed with MPA based on the findings of positive perinuclear antineutrophil cytoplasmic antibody along with findings on kidney biopsy. Nerve conduction study showed symmetric sensorimotor polyneuropathy. We followed the patient for 3 years, and she showed good functional outcome after immune-modulating therapy although Five-Factor Score more than 2 at diagnosis.

Churg-Strauss syndrome (CSS) is a rare systemic vasculitis that affect small and medium-sized blood vessels and is accompanied by asthma, eosinophilia, and peripheral neuropathy. This report describes a case of a 52-year-old man who had a history of sinusitis, asthma, and thymus cancer and who had complained of bilateral lower extremity paresthesia and weakness for a month. Peripheral neuropathy was detected by electrodiagnostic studies. Resection of a mediastinal mass, which was diagnosed as thymic neuroendocrine carcinoma, was performed five months before his visit. After thymectomy, peripheral blood tests revealed a gradual increase in eosinophils. Two months after surgery, he was admitted to the hospital for dyspnea, and nodules of focal consolidation were found in his chest X-ray. One month later, pyoderma occurred in the right shin, and the skin biopsy showed extravascular eosinophilic infiltration. He was diagnosed with CSS after thymectomy, and we report a very rare case of CSS presented with thymic neuroendocrine carcinoma.

OBJECTIVE: To determine whether patients with lumbosacral (LS) radiculopathy and peripheral polyneuropathy (PPNP) exhibit sudomotor abnormalities and whether SUDOSCAN (Impeto Medical, Paris, France) can complement nerve conduction study (NCS) and electromyography (EMG). METHODS: Outpatients with lower extremity dysesthesia underwent electrophysiologic studies and SUDOSCAN. They were classified as normal (group A), LS radiculopathy (group B), or PPNP (group C). Pain severity was measured by the Michigan Neuropathy Screening Instrument (MNSI) and visual analogue scale (VAS). Demographic features, electrochemical skin conductance (ESC) values on hands and feet, and SUDOSCAN-risk scores were analyzed. RESULTS: There were no statistical differences in MNSI and VAS among the three groups. Feet-ESC and hands-ESC values in group C were lower than group A and B. SUDOSCAN-risk score in group B and C was higher than group A. With a cut-off at 48 microSiemens of feet-ESC, PPNP was detected with 57.1% sensitivity and 94.2% specificity (area under the curve [AUC]=0.780; 95% confidence interval [CI], 0646–0.915). With a SUDOSCAN-risk score cut-off at 29%, NCS and EMG abnormalities related to LS radiculopathy and PPNP were detected with 64.1% sensitivity and 84.2% specificity (AUC=0.750; 95% CI, 0.674–0.886). CONCLUSION: SUDOSCAN can discriminate outpatients with abnormal electrophysiological findings and sudomotor dysfunction. This technology may be a complementary tool to NCS and EMG in outpatients with lower extremity dysesthesia.

Thoracic outlet syndrome (TOS) is an uncommon condition that can occur when the nerves, artery, or vein to the arm is compressed by one or more of the structures that make up the thoracic outlet. TOS was the first compression neuropathy of the upper extremity to be identified. The wide variability of patients' symptoms, which include vascular and neural signs, as well as diffuse symptoms, and the lack of a valid and reliable test to confirm the diagnosis of TOS makes it difficult to identify correctly patients with TOS. Rates of three to 80 cases per 1,000 patients have been reported, but more patients are likely to have TOS because it is underestimated. Additionally, the primary controversy regarding patients with TOS is related to symptoms such as paresthesia, numbness, and pain. No positive objective test exists to confirm an accurate diagnosis. If patients present with diffuse pain and numbness in the neck and upper extremity with more than 2 provocation tests, TOS could be considered. The purpose of this review is to provide an overview of the causes, classification, evaluation, and management of TOS.

The median nerve is the most important nerve in the upper extremity, as it is responsible for most of the sensation of the hand, the fine motor functions of the thumb, and finger grasping. Median neuropathies most commonly occur as compressive neuropathy or entrapment neuropathy, but sometimes as neuritis without any compressive lesion. Carpal tunnel syndrome (CTS), anterior interosseous nerve syndrome, and pronator teres syndrome are the subtypes of median nerve neuropathies, of which CTS is the most common. Median neuropathies can be diagnosed clinically by careful history-taking and a physical examination. Typical symptoms of CTS include night pain (crying), a tingling sensation of the radial digits, numbness or paresthesia, clumsiness, and atrophy of the thenar muscles. Electrophysiologic testing can be used for confirmation of the diagnosis and for documentation before surgical treatment. Imaging modalities including ultrasonography or magnetic resonance imaging can be used to ensure diagnostic accuracy and to detect unusual causes of compression. Conservative treatments include rest, bracing, nerve stretching, non-steroidal anti-inflammatory drugs, and steroid injections. If nonsurgical approaches are unsatisfactory or the nerve damage is severe, surgical treatment should be considered. Carpal tunnel release for CTS is a relatively simple procedure that involves division of the transverse carpal ligament and decompression of the median nerve. Early diagnosis and proper management are important, as muscle atrophy and sensory loss may persist when surgical release is delayed in patients with advanced disease.

An abdominal aortic aneurysm (AAA) is a regional dilatation diameter of greater than 3 cm of the abdominal aorta. Clinical manifestations include abdominal pain with a pulsatile mass, back and/or leg pain; however, AAA is typically asymptomatic. A ruptured AAA can result in severe abdominal pain, back pain, and hypovolemic shock, and may result in eventual death. Cases of ruptured AAAs have been reported frequently and are typically encountered in emergency departments. However, acute occlusion of AAA is an uncommon vascular emergency with a high mortality rate. We encountered a patient with sudden-onset abdominal and back pain, coldness, paresthesia, and loss of motor function in both lower extremities after experiencing sustained abdominal compression for 3 minutes. Despite rapid diagnosis and treatment, the patient died 2 days post-operation due to reperfusion injury. This report discusses the rare occurrence of an acute occlusion of AAA due to thrombosis; our aim is to increase awareness of this diagnosis in emergency departments.
