Radiographs of an 11-year-old boy who presented with pathological fracture of the left humerus. a-b Anteroposterior and lateral radiograph on admission. c-d MRI indicates a low signal on T1-weighted images and a homogeneous high signal on T2 weighting. e-f Three-dimensional CT image reconstruction and a sagittal CT scanning show fracture of proximal humeral bone cyst. g-l After the operation of minimally invasive intramedullary decompression and drainage with ESIN combined with intralesional injections of steroids; At the interval points of postoperative 1 weeks, 2 months, 6 months, the lesion is significantly smaller and shows signs of healing gradually, the fracture gradually healed, Radiographs show complete cyst healing (Capanna grade 1 healing)
