Intestinal metastasis causing intussusception in a patient treated for osteosarcoma with history of multiple metastases: a case report.
Intestinal intussusception caused by metastatic tumors is a very rare condition. Preoperative diagnosis is not easy because of the condition's rarity and because of mild abdominal physical presentation. We report on a patient with osteosarcoma who suffered from abdominal pain and emesis during the period of autologous peripheral blood stem cell transplantation. He had undergone tumor excision and radiotherapy several times prior to autologous peripheral blood stem cell transplantation because of multiple metastases. Intestinal metastasis was suspected initially by computed tomographic scan and sonogram and was proved by surgical resection and pathological findings. Clinicians caring for pediatric patients with osteosarcoma with a history of multiple metastases should consider the possibility of intestinal metastases when equivocal abdominal symptoms develop after intensive chemotherapy.
