Successful endovascular removal of a chondroblastic osteosarcoma embolus within the left middle cerebral artery

A Case of Pediatric Stroke: Osteosarcoma Embolus in the Internal Carotid Artery

Stroke in the pediatric population is rare. Despite presentation similar to that seen in the adult patient, the diagnosis in a child can be missed or mistaken for a more common stroke mimic. Due to its rarity, there are no completed pediatric clinical trials investigating best treatment, though guidelines have been extrapolated from adult guidelines and retrospective cohort studies to include some combination of thrombolysis and mechanical thrombectomy. Rarer still is pediatric stroke caused by tumor embolus. We present the case of a young child diagnosed with stroke secondary to osteosarcoma embolism to the left internal carotid artery and review the relevant literature to discuss the considerations and challenges of treatment of stroke in the pediatric population.
