Brown-Séquard syndrome as a presentation of idiopathictransverse myelitis.

Brown-Séquard syndrome refers to a set of signs and symptoms caused by hemisection of the spinal cord from various sources. It may have multiple causes; traumatic injuries are the most frequent ones. The less common causes include inflammation, ischemia, tumors, or infections.

Intraneural perineuriomas: diagnostic value of magnetic resonance neurography.

Intraneural perineurioma (IP) is an under-recognized hypertrophic peripheral nerve tumor. It affects young patients involving frequently the sciatic nerve and its branches and presents with a progressive, painless and predominantly motor deficit. Magnetic resonance neurography (MRN) is a useful tool to localize the lesion, evaluate its extension, and discriminate between different etiologies.

Epileptic spasms in clusters with focal EEG paroxysms: A study of 12 patients.

Objective: We analyzed the electroclinical features, etiology, treatment, and outcome of 12 patients with West syndrome (WS) associated with focal hypsarrhythmia (FH).

Methods: Between February 2005 and July 2013, 12 patients met the electroclinical diagnostic criteria of WS associated with FH. Hypsarrhythmia was considered to be focal when two or three brain lobes were involved.
