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)
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)
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)
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)
