Intramuscular myxomas are benign tumors. This study presents two cases with imaging features that differ from previously reported characteristics in CT and MRI scans.

Area of Science:

  • Radiology
  • Oncology

Background:

  • Intramuscular myxoma is a benign mesenchymal tumor characterized by bland spindled cells within a myxoid stroma.
  • Computed tomography (CT) typically shows these lesions as well-demarcated, homogeneous, low-density masses within skeletal muscle.
  • Magnetic resonance (MR) imaging literature is limited, but generally describes intramuscular myxoma as a homogeneous mass with specific signal intensities on T1- and T2-weighted sequences.

Observation:

  • This report details two cases of intramuscular myxoma.
  • The imaging characteristics in these cases deviate from the established CT and MR findings previously documented in medical literature.

Findings:

  • The two presented cases exhibit distinct imaging features on CT and MR that differ from the typical presentation of intramuscular myxoma.

  • These variations highlight the potential for atypical imaging appearances of this benign tumor.

    • Implications:

    • The findings suggest that radiologists should consider intramuscular myxoma even when imaging findings do not precisely match the classic descriptions.
    • Recognizing atypical presentations is crucial for accurate diagnosis and appropriate patient management of intramuscular myxoma.
