Osseous metastasis (OM) in ovarian cancer (OC) are rare, with an incidence ranging from 0.8% to 2.6%, and are associated with poor prognosis. The available literature on their management and associated complications is scarce. We report a case of International Federation of Gynecology and Obstetrics (FIGO) stage IVB clear cell epithelial OC (EOC) who presented with neck pain. Imaging revealed multiple cervical spine metastases with left vertebral artery encasement and concurrent C1 lateral mass compression fracture, without neurological deficit, requiring occiput to C2 posterior instrumentation and fusion. Early OM may be associated with shorter overall survival, and survival after OM diagnosis is on the order of months. Management of OM should include a multidisciplinary team and may require surgical stabilization in addition to systemic chemotherapy, local radiotherapy, and osteoclast inhibitors., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Sassine et al.)

Over 80% of patients with epithelial ovarian cancer present with advanced disease, FIGO stage III or IV at the time of diagnosis. The majority require extensive upper abdominal surgery to obtain complete gross resection. This may include splenectomy, distal pancreatectomy, partial hepatectomy, cholecystectomy, and usually diaphragmatic peritonectomy or resection. Following surgery, diaphragmatic hernia-a very rare but serious complication-may occur. We describe four cases of left-sided diaphragmatic hernia resulting after debulking surgery, which included left diaphragm peritonectomy and splenectomy, in patients with advanced ovarian cancer. In association with the current shift towards more extensive debulking surgery for ovarian cancer, more patients may present with postoperative left-sided diaphragm hernia, making the prevention, diagnosis, and management of this complication important to practicing gynecologic oncologists. Intraoperatively the diaphragm should be checked thoroughly to rule out any defects, which should be closed. A diaphragmatic hernia may be easily misdiagnosed because the patient can present with various symptoms. While rare, these hernias require prompt identification, intervention and surgical correction to avoid serious complications., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2021 The Authors.)
