Conclusion
- The potential imaging findings in the various,
sometimes rare,
muscular disorders are helpful for accurate diagnosis.
- Beyond the common MRI features,
we also describe some additional “pearls” that may be key points for reaching the differential diagnosis.
- Of all our review we emphasize the importance of:
- Detection of fatty nodules within cystic muscle lesions may be a
pathognomonic finding of intramuscular hydatid disease.
- The sign described by us as "butterfly wings" in the gluteal muscle
disorders can be a pathognomonic finding of gluteal compartment
syndrome.
- In the context of multifocal muscle edema,
the detection of high
signal and enhancement of nerve roots and trunks should address the
diagnosis of neuropathy,
specially in diabetis.
- In a neoplasic disease with multifocal muscle edema pattern,
the use
of gadolinium may reveal unsuspected nodular lesions consistent with
unexpected metastases.
