โฆ Synopsis
A 22-year-old male awoke with right foot drop and numbness.
CASE OF THE MONTH
Nerve conduction studies, sural nerve biopsy, and molecular genetic analysis were consistent with hereditary neuropathy with liability to pressure palsy Section Editors (HNPP). Two months later he developed involuntary flexion/extension movements of the right toes with associated intermittent dystonic flexion of the Robert C. Griggs, MD right foot. Over the next 2 months these movements spread to the left foot Rochester, New York and hand and myoclonus of the left trapezius and rhomboid appeared. This Jerry R. Mendell, MD is the first case report of moving toes syndrome and segmental myoclonus Columbus, Ohio in association with HNPP. The temporal and topographic patterns of spread of the abnormal movements suggest a central mechanism probably induced

Hereditary neuropathy with liability to pressure palsies (HNPP) is usually caused by a 1.5-Mb deletion in chromosome 17~11.2, the inverse mutation to the duplication seen in the majority of Charcot-Marie-Tooth type 1A (CMT IA) patients. Although most patients with HNPP present with pressure palsies
Hereditary neuropathy with liability to pressure palsy (HNPP) is typified as isolated nerve palsies caused by trivial compression or trauma. It rarely presents in two extremities and even more infrequently affects all four limbs simultaneously. We present a patient who concurrently experienced right
## Abstract __Introduction__: Diagnostic nerve ultrasound is becoming more commonly used by both radiologists and clinicians. The features of different neuromuscular conditions must be described to broaden our understanding and ability to interpret findings. __Methods__: Our study examines the sono
