To illustrate the spectrum of muscular hypotrophy secondary to neuropraxia. To assess the advantages of the MRI.
muscular hypotrophy is a process that can develop in a few days to several weeks.
Commonly the etiology is linked to a disorder like nerve conduction called neuropraxia.
Usually can be compressive etiology,
with myelin damage,
but not axon injury.
Muscular hypotrophy attends silently going unnoticed in early stages.
But its evolution is progressive and may manifest in chronic functional and postural disorders.
MRI (1.5 T) accurately shows the muscles involved and the site of nerve injured.
Imaging findings OR Procedure details
conducted a retrospective analysis muscular system MRI of the spine,
scapular and pelvic waist.
Muscle hypotrophy develops similarly in different regions of the body on MRI.
It details the marked loss of muscle volume,
engaged fatty replacement which occupies anatomical compartment.
Sequences that best represent are those which achieve a good contrast of soft tissues such as T1 or T2 with short TE.
MRI is an excellent diagnostic tool for the specific demonstration of the affected muscles in cases of hypotrophy.
Early diagnosis avoids postural disorders or positions that overload other joints.
contributes to the treatment to develop synergistic muscles that can supply the function.
