  • Figure 1
    Coronal images
     

    Coronal FSE T2-weighted MR image shows the heterogeneous high signal intensity of the lesion with a large cyst and neighboring numerous small cysts, and hypointense septations in betwen them.

     
    Area of Interest: unknown; Imaging Technique: Coronal images;

    Coronal SE T1-weighted MR image shows the heterogeneous intermediate signal intensity of the lesion with a large cyst and neighboring numerous small cysts, and hypointense septations in between them.

     
    Area of Interest: unknown; Imaging Technique: Coronal images;

    Sagittal image

    Sagittal FSE T2-weighted MR image of the left tibia shows a metaphyseal-based aneurysmal bone cyst which is expansile, eccentrically located, causing cortical thinning. It shows hemorrhagic fluid-fluid levels...

    Axial SE T1-weighted MR image shows the aneurysmal bone cyst which is expansile, eccentrically located, causing cortical thinning. It shows hemorrhagic fluid-fluid level clearly.

     
    Area of Interest: unknown; Imaging Technique: Axial images;

    Axial GRE T2-weighted MR image shows the aneurysmal bone cyst which is expansile, eccentrically located, causing cortical thinning. It shows hemorrhagic fluid-fluid level clearly.

Sagittal FSE T2-weighted MR image of the left tibia shows a metaphyseal-based aneurysmal bone cyst which is expansile, eccentrically located, causing cortical thinning. It shows hemorrhagic fluid-fluid levels clearly both in the large cyst and the small cyst located just anterosuperior to the large cyst.
