Pelvic pseudotumor following total hip arthroplasty. Case report

According to the literature, the development of metallosis after hip arthroplasty occurs in approximately 5% of patients. Metallic debris in the joint results in massive local and systemic release of cytokines. Excision of the pelvic pseudotumor, as well as revision surgery, is mandatory if there is evidence of osteolysis and loosening of the endoprosthesis. Imaging diagnostics, including magnetic resonance and computed tomography, are crucial for the preoperative planning of surgical intervention

Giant pelvic well-differentiated liposarcoma

Herein, we report a case of a giant well-differentiated liposarcoma located subgluteally and extending into the pelvis through the obturator foramen, nearby the urinary bladder and rectum without causing functional disturbances. The tumor was removed simultaneously with transgluteal posterior and anterior transabdominal approach. Six months postoperatively, no clinical and radiological evidence of recurrence was observed
