case_images: On radiological investigations, X-ray of pelvis with both hips showing osteolytic involvement of the right acetabulum area (Fig. 1a). This mass appeared hypointense in T1-weighted images with central area of hyper-intensity suggesting blood products, and hyper-intense on T2 and short tau inversion recovery images, giving an appearance similar to aneurysmal bone cysts (Fig. 1b). Computed tomography (CT) was done to see the bony involvement of the area and it showed expansile lobulated lytic mass lesion centered in the right acetabulum involving acetabular margins of hip joint (Fig. 1c). To overcome this problem, a pre-operative CT angiography was done (Fig. 1d) and plan was made to embolizing the feeding vessels preoperatively using the findings of CT angiography. T-shaped incision to approach the tumor (Fig. 1e). Now, a 30 x 30 cm prolene mesh was taken and molded according to the defect just created, and fixed to the bone as well as the soft tissue with the help of absorbable sutures so as to repair the defect, while keeping the neurovascular structures in mind and being careful not to injure them (Fig. 1f).
