    Area of Interest: unknown; Imaging Technique: Plain film of the left humerus;

    Enlargement shows numerus radiolucent areas of the humeral shaft at the distal part of the bone.

    Computed tomography examination
     

    Computed tomography examination shows significant destruction of the trabecular bone of the humeral head and polycystic appearance of the bone marrow with regional calcifications into the lumen

     
    Area of Interest: unknown; Imaging Technique: Computed tomography examination;

    Additionally, a large cystic lesion between medial and lateral head of the triceps muscle with some foci of calcifications are observed

    99mTc-DMP scintigraphy

    99mTc-DMP scintigraphy shows significant deposition of the radionuclide at the distal part of the left humerus and elbow as well as a smaller deposition foci at the upper 1/3 of it.

     
    Area of Interest: unknown; Imaging Technique: 99mTc-DMP scintigraphy;

    Magnetic Resonance examination
     

    Sagital T1-weighted MR image demonstrates the multilocular nature of the lesion into the humeral lumen with a cystic lesion with high signal intensity due to hemorrage, involving the soft tissues of the upper arm.

     
    Area of Interest: unknown; Imaging Technique: Magnetic Resonance examination;

    Coronal T2-weighted MR image shows the high signal intensity of the cyst.

Plain film of the left humerus demonstrates distortion of the axis, regional expansion of the humeral shaft with minimal thinning areas of the cortex. Additionally, numerus radiolucent areas of the humeral shaft are observed especially at the distal part of the bone. No calcification of the soft tissues is noticed.
