4. CONCLUSION
IMM is a rare benign soft tissue tumor that is caused by incomplete
differentiation of fibroblasts from mesenchymal cells in skeletal
muscles. MRI allows the diagnosis of IMM and its differentiation from
other skeletal muscle lesions, which is confirmed by the
histopathological evaluation of the lesion after biopsy. This benign
lesion has a fast growth and has a good prognosis after surgery and
removal.
