    Area of Science:

    • Radiology
    • Medical Imaging
    • Gaucher Disease Research

    Background:

    • Gaucher disease is a lysosomal storage disorder affecting multiple organs.
    • Skeletal, splenic, and hepatic involvement are characteristic manifestations.
    • Accurate assessment of disease extent is crucial for patient management.

    Purpose of the Study:

    • To evaluate the utility of magnetic resonance (MR) imaging in assessing Gaucher disease.
    • To characterize MR imaging findings in the skeletal system, spleen, and liver.
    • To correlate MR imaging findings with disease severity and complications.

    Main Methods:

    • Retrospective analysis of MR imaging studies in five patients with confirmed Gaucher disease.
    • Detailed examination of signal intensities and relaxation times (T1 and T2) in bone marrow, spleen, and liver.
    • Correlation of imaging findings with clinical presentation, including bone pain.

    Main Results:

    • Homogeneous low-intensity signals in long bone marrow, vertebrae, and hips, indicating altered T1 and T2 relaxation times.
    • Normal signals observed in specific epiphyses in some patients.
    • Increased tibial marrow signal intensity in patients with acute bone pain, linked to fluid accumulation post-avascular episode.
    • Readily visible liver and spleen enlargement, particularly on coronal MR images.
    • Significantly shorter T1 values in the spleen compared to normal.

    Conclusions:

    • MR imaging is highly effective for assessing the extent of Gaucher disease involvement in the liver, spleen, and bone marrow.
    • Distinct MR imaging signal characteristics can identify affected tissues and potential complications like avascular episodes.
    • MR imaging provides valuable insights for understanding Gaucher disease pathophysiology and guiding treatment strategies.
