Partial cranial internal hemipelvectomy in a feline patient with ilial osteosarcoma – a case report

. Surgical margins were clear, with a minimum 9-mm tumour-free margin. The cat recovered well, resumed normal activity by 3 weeks, and had no lameness. Adjuvant carboplatin chemotherapy was administered 20 days postoperatively and was continued for six cycles. Follow-up thoracic radiographs at multiple intervals showed no metastasis, and pelvic radiographs at 6 months revealed no local recurrence or pelvic disruption. At 473 days postsurgery, the cat remained active and disease-free. This case supports partial cranial internal hemipelvectomy as a viable option for feline ilial wing osteosarcoma.
