Sarcoidosis is an inflammatory granulomatous disease that is systemic, but bone involvement is uncommon. A 68-year-old man was referred to our hospital complaining of right shoulder pain with numbness. Computed tomography revealed systemic lymphadenopathy and multiple bone lesions. Because malignant lymphoma with a mass lesion protruding into the vertebral canal was considered, he underwent urgent radiotherapy. Thereafter, a needle biopsy of the left parasternal node was performed and showed epithelioid granulomas, confirming a diagnosis of sarcoidosis...

INTRODUCTION: Sensory feedback from the foot dorsum during walking has only been studied globally by whole nerve stimulation. Stimulating the main nerve innervating the dorsal surface produces a functional stumble corrective response that is phase-dependently modulated. We speculated that effects evoked by activation of discrete skin regions on the foot dorsum would be topographically organized, as with the foot sole. METHODS: Nonnoxious electrical stimulation was delivered to five discrete locations on the dorsal surface of the foot during treadmill walking...

Tumours formed from peripheral nerve sheaths are rare in the shoulder. We present the case of a 80-year-old female referred to an orthopaedic surgery clinic because of a large painless mass of the right shoulder, with one year of evolution. There was no history of trauma, involvement of any other joint or systemic complaints. Given the clinical and imagiological suspicion of a giant synovial cyst, the patient underwent complete surgical resection of the mass, which took place without any complications or functional impairment...

BACKGROUND: A deep characterization of neurological patients is a crucial step for a detailed knowledge of the pathology and maximal exploitation and customization of the rehabilitation therapy. The muscle synergies analysis was designed to investigate how muscles coactivate and how their eliciting commands change in time during movement production. Few studies investigated the value of muscle synergies for the characterization of neurological patients before rehabilitation therapies...

Spinal cord lipomas are usually associated with spinal dysraphism and is most common in lumbosacral region. Spinal intradural lipoma is a rare condition accounting for less than 1% of spinal cord tumours and is most prevalent in cervicodorsal region. Intramedullary spinal cord lipoma of cervical spine not associated with spinal dysraphism is one of the rarest lesions. They usually present insidiously with slowly progressive myelopathic deficits. We present a case of nondysraphic intramedullary spinal cord lipoma with exophytic component and intracranial extension...

INTRODUCTION: Symptoms and signs of functional (psychogenic) motor and sensory disorder are often said to be dependent on the patients' idea of what symptoms should be, rather than anatomy and physiology. This hypothesis has however rarely been tested. MATERIALS AND METHODS: Inspired by a brief experiment carried out in 1919 by neurologist Arthur Hurst we aimed to assess the views of healthy non-medical adults towards paralysis and numbness and their response to tests for functional disorders when asked to pretend to have motor and sensory symptoms...

Neuralgic amyotrophy of the shoulder (Parsonage-Turner syndrome) is a rare condition of unknown aetiology which manifests as acute neuropathy of the brachial plexus. Diagnosis is based on typical symptoms and physical examination. In addition, magnetic resonance imaging of the affected shoulder and the cervical spine is advisable, in order to distinguish this syndrome from other conditions with similar symptoms. There is no specific treatment for neuralgic amyotrophy, but in about 50 - 67% of cases complete recovery occurs within two to three years, depending on the severity of the symptoms when they first appear...

BACKGROUND: Supernumerary phantom limb (SPL) is a rare neurologic phenomenon, in which a patient misperceives an extra limb in addition to the original set of limbs. We report a case of SPL in a patient with a right basal ganglia hemorrhage and review the previous literature about this peculiar phenomenon. CASE PRESENTATION: Two days after the event of a right basal ganglia hemorrhage, a 78-year-old male reported a phantom arm protruding from his left shoulder. He could not see or touch the phantom arm but he felt the presence of an addition arm lateral to his paretic arm...

Lesions of the axillary artery and consequent compression of the brachial plexus are extremely rare in patients with glenohumeral dislocation and may have greatly varying clinical manifestations. This joint is one of the most affected by dislocation in the human body, accounting for approximately 45% of cases. Less than 1% of patients with shoulder dislocation have vascular complications; however, when there is damage in the axillary artery, the incidence of associated brachial plexus injury is 27% to 44%. The authors report on a case of brachial plexus compression by an axillary artery pseudoaneurysm after a glenohumeral dislocation, aiming to highlight the existence of this association, in order to make an early diagnosis and avoid serious complications, such as neurologic injury...

BACKGROUND: Patients with adhesive capsulitis are commonly seen by physical therapists. Pain and limited shoulder motion from adhesive capsulitis have at times been linked to neural irritation. The purpose of this case is to describe the examination and intervention of a patient with adhesive capsulitis who appeared to have a coexisting, underlying neural irritation. This paper emphasizes how the neurological component must initially be identified and addressed for a successful outcome...

We report a 40-year-old man who presented with multiple bone pseudofractures after about 20 years from the onset of Wilson's disease (WD). At age 36, he first noticed pain in his left shoulder. At age 39, he had multiple chest pain. On neurologic examinations, dysarthria and dysphagia due to pseudobulbar palsy, rigidity and tremor on right upper lim were observed. WD was confirmed because of low levels of plasma cupper and ceruloplasmin in addition to ATP7B gene mutation. The chest X-ray revealed multiple fractures of the several ribs...
