Sonographic Evaluation of the Peripheral Nerves in Hereditary Neuropathy With Liability to Pressure Palsies: A Case Report
نویسندگان
چکیده
Hereditary neuropathy with liability to pressure palsies (HNPP) is an autosomal dominantly inherited disorder that affects peripheral nerves by repeated focal pressure. HNPP can be diagnosed by clinical findings, electrodiagnostic studies, histopathological features, and genetic analysis. Ultrasonography is increasingly used for the diagnosis of neuromuscular diseases; however, sonographic features of HNPP have not been clearly defined. We report the sonographic findings and comparative electrodiagnostic data in a 73-year-old woman with HNPP, confirmed by genetic analysis. The cross-sectional areas of peripheral nerves were enlarged at typical nerve entrapment sites, but enlargement at non-entrapment sites was uncommon. These sonographic features may be helpful for diagnosis of HNPP when electrodiagnostic studies are suspicious of HNPP and/or gene study is not compatible.

متن کاملA transgenic mouse model for human hereditary neuropathy with liability to pressure palsies.
Mutations in the gene encoding peripheral myelin protein 22 (PMP22) account for several inherited peripheral neuropathies in humans. We now show that transgenic mice expressing antisense PMP22 RNA exhibit modestly reduced levels of PMP22 together with a phenotype that is reminiscent of hereditary neuropathy with liability to pressure palsies (HNPP), a human disease caused by a 1.5-Mb deletion o...
متن کاملMuscle training‐induced bilateral brachial plexopathy in an adolescent with sporadic hereditary neuropathy with liability to pressure palsies
There have been few studies regarding physical training-induced peripheral nerve dysfunction in patients with hereditary neuropathy with liability to pressure palsies (HNPP), with the exception of soldiers that trained intensively. Here, we report a 15-year-old boy without family history of HNPP who developed bilateral painless brachial plexopathy following short-term barbell and plank training...
متن کاملHereditary neuropathy with liability to pressure palsy.
Hereditary neuropathy with liability to pressure palsy (HNPP) is an autosomal dominant disease with sensory and motor nerve palsies usually precipitated by trivial trauma or compression. In the majority of cases HNPP is caused by deletion of the peripheral myelin protein 22 gene (PMP22) on chromosome 17p11.2. The authors present a family case with genetically proven HNPP.
متن کاملHereditary neuropathy with liability to pressure palsy: fulminant development with axonal loss during military training.
Hereditary neuropathy with liability to pressure palsy (HNPP) is characterised by recurrent mononeuropathies following minor trauma. We describe a case of fulminant HNPP beginning on the first day of military physical training. Protracted weakness, muscle atrophy, hand contractures, and multifocal sensory loss developed during a further three weeks of basic training. Nerve conduction changes we...
