INTRODUCTION: Hypervascularization of nerves has been shown to be a pathological sign in some peripheral nerve disorders, but has not been investigated in nerve trauma. METHODS: An observational cohort study was performed of the intraneural blood flow of 30 patients (34 nerves) with penetrating nerve injuries, before or after nerve reconstruction. All patients underwent electrophysiological assessment, and B-mode and color Doppler ultrasonography. RESULTS: Intraneural hypervascularization proximal to the site of injury was found in all nerves, which was typically marked and had a longitudinal extension of several centimeters...

INTRODUCTION: The etiology of calf pain varies widely; therefore, it is difficult to diagnose and requires careful history taking and physical examination by primary care unit physicians. Because ultrasonography is easy to perform, cheap, and readily available with physicians during a routine consultation, it is the first choice of modality for the evaluation of calf pain. However, simple inflammation around the nerve should also be considered as a possible etiology. Here we describe a 35-year-old man with chronic pain in the right calf that was actually caused by fibroma-induced chronic inflammation around the tibial and peroneal nerves but misdiagnosed as centralized neuropathic pain...

BACKGROUND: Amputation neuromas (ANs) are reactive hyperplasia of nerve tissues that occur after a trauma or surgery involving the peripheral nerves. Only two previous reports of ANs occurring around the stomach and post gastrectomy have been reported. We report the case of a patient with AN near the remnant stomach who underwent distal gastrectomy for gastric cancer. CASE PRESENTATION: A 76-year-old man underwent distal gastrectomy, D1+ lymphadenectomy, and Billroth-I reconstruction for early gastric cancer in another hospital at 63 years of age...

BACKGROUND: Electrical stimulation of the greater occipital nerves is performed to treat pain secondary to chronic daily headaches and occipital neuralgia. The use of fluoroscopy alone to guide the surgical placement of electrodes near the greater occipital nerves disregards the impact of tissue planes on lead stability and stimulation efficacy. OBJECTIVE: We hypothesized that occipital neurostimulator (ONS) leads placed with ultrasonography combined with fluoroscopy would demonstrate increased survival rates and times when compared to ONS leads placed with fluoroscopy alone...

The technical advances in sonography of the past decade have supported the rapid improvement of high-resolution imaging, which enables the quick visualization of peripheral nerves at relatively limited costs. Recently, the possibility of visualizing the extratemporal facial nerve (FN) has been considered. This manuscript describes the first systematic evaluation in cadavers, of a novel ultrasonographic approach with this specific aim. Eight cadaveric hemifaces were evaluated by means of high-frequency ultrasound with two linear (13 and 22 MHz) and a convex transducer (6...

Ultrasonography (US) of peripheral nerves has gained wide popularity because of the increased definition of modern high-frequency electronic transducers, as well as the well-known advantages of US, which include easy availability, low cost, and the possibility of realizing a dynamic examination. Traditionally, US has been deployed to assess the major nerves of the limbs. More recently, US has also been used to assess the normal appearance and pathologic changes of smaller subcutaneous nerves. The sural nerve is a small sensory nerve in the subcutaneous tissues of the calf that can be affected by a variety of disorders...

The WHO reports that one of the major chronic conditions affecting the elderly worldwide is musculoskeletal disorders that are associated with long-term pain and disability. Considering the healthcare needs of the elderly (i.e. comprehensive, accessible, efficient) and the advantages of ultrasound (US) use (patient-friendly, convenient, cost-effective, and does not require exposure to radiation or magnetic fields), there seems to be a 'gap' in the actual clinical practice. In this paper, we aimed to highlight the potential value of US imaging in the management of the elderly with a wide spectrum of musculoskeletal conditions (degenerative/rheumatic joint diseases, falls/trauma, nursing care, peripheral nerve problems, sarcopenia, and interventions)...

INTRODUCTION: Neurofibromatosis type 2 (NF2) is mainly associated with central nervous system (CNS) tumors. Peripheral nerve involvement is described in symptomatic patients, but evidence of subclinical peripheral nerve involvement is scarce. METHODS: We conducted a cross-sectional pilot study in 2 asymptomatic and 3 minimally symptomatic patients with NF2 to detect subclinical peripheral nerve involvement. Patients underwent clinical examination, nerve conduction studies (NCS), and high-resolution ultrasonography (HRUS)...
