case_images: Anteroposterior and lateral radiograph of the left femur demonstrating an acute versus subacute incomplete transverse fracture of the subtrochanteric zone.

case_images: During this visit, a radiograph of her left femur was obtained, which demonstrated lateral cortical thickening and an incomplete transverse fracture line in a skeletally mature femur (Figure 1).
case_images: MRI of bilateral distal femora, PD TSE FS sequence, coronal view, demonstrating serpentine line of abnormal signal intensity with surrounding edema in subcortical bone of the lateral femoral condyle, consistent with avascular necrosis.

case_images: Eight years after her CML diagnosis and while being on imatinib therapy, she was diagnosed with bilateral distal femur avascular necrosis (Figure 2).
case_images: MRI without contrast, T2 sequence, sagittal and axial cut, with a bilateral L4 pars defect with associated bone marrow edema.

case_images: Imaging studies at the time demonstrated L4 bilateral pars defects with bone marrow edema (Figure 3).
case_images: Radiographs of the right foot showing chronic incomplete fractures of the shafts of the third and fourth metatarsals.

case_images: She was then diagnosed with fractures of the third and fourth metatarsal shafts (Figure 4).
case_images: Anteroposterior and lateral radiograph of the left femur demonstrating internal fixation of the subtrochanteric atypical fracture.

case_images: Synthes (West Chester, Pennsylvania, United States) (Figure 5). Samples of the femur obtained during the surgery were sent for pathology analysis and demonstrated viable cortical and trabecular bone architecture, with preserved osteocyte lacunae and no evidence of necrosis.
case_images: Microscopic image H&E x 10 demonstrating bone trabeculae and bone marrow without conspicuous abnormalities and no evidence of atypical cells. Limited presence of fibrosis interspersed among the bone trabeculae, suggesting that a reparative process or chronicity was also noted in the sample.

case_images: The findings are consistent with a healing response in the context of an AFF, lacking signs of acute inflammation or malignancy (Figure 6).
case_images: Anteroposterior and lateral radiograph of the left femur demonstrating healing of the previously noted fracture.

case_images: At the 9-month follow-up, the radiographs demonstrated evident signs of fracture healing with an imperceptible fracture line (Figure 7).
