The purpose of the study was to prospectively assess magnetic resonance (MR) imaging findings of lower limb musculature in an axonal Charcot-Marie-Tooth disease (CMT2) pedigree due to mutation in the dynamin 2 gene (DNM2). The series comprises a proband patient aged 55 years and her two affected daughters aged 32 and 23. MR imaging study included T1- and(More)
Malignant peripheral nerve sheath tumors (MPNST) are rare. We report a case of a MPNST of the proximal sciatic nerve in the thigh, unassociated with pre-existing type 1 neurofibromatosis or history of radiation therapy. A 71-year-old man had a 6 month history of constant, severe, burning pain affecting the sole of the left foot. One month after the onset,(More)
MR arthrography has become an important tool for the assessment of a variety of ankle disorders. MR arthrography permits more sensitive imaging of suspected intra-articular pathology in cases in which conventional MR imaging is either insufficient or inadequate for diagnosis or treatment planning. The main indications for MR arthrography are the evaluation(More)
112 The high resolution, sensitivity and specificity of magnetic resonance imaging for aortic disease is well recognized and supported by the literature. We present a clinical case in which this technique was essential for focussing the decision on the type of surgery to perform. A 67-year-old man, ex-smoker, with essential hy-pertension of several years'(More)
Meningiomas are unusual in childhood, and the intraspinal location is very uncommon. Those arising from lumbar dura matter are the most rare among spinal neoplasms of meningeal origin. We present the case of a 12-years-old girl with a cauda equina meningioma. As in previously reported cases, the initial complain was back pain with radicular irradiation. The(More)
We report on the clinical, electrophysiological, and lower-limb musculature MRI findings in a severe demyelinating Guillain-Barré syndrome (GBS) patient with follow-up over 6 months. After 3 weeks of tetraplegia and mechanical ventilation, there was progressive improvement until almost complete recovery. On day 4 after onset, electrophysiological study(More)
Intradural disc herniation is a rare complication of degenerative disc disease. A correct diagnosis of this process is frequently difficult. If this entity is not preoperatively diagnosed and is omitted at surgery, severe neurologic sequels may be provoked. We report a case of a pathologically proven intradural disc herniation preoperatively diagnosed by MR(More)
Speed and differential speed measurements are necessary for almost all of manufacturing steel processes. Use of incremental rotary encoder is the cheapest method for this purpose. Classical theoretical algorithms are analyzed in terms of error and sampling time. These methods are used for a Temper mill real case, showing the practical limitations in both(More)
