BACKGROUND: @entity2846 is a rare intracranial @entity5 derived from choroid plexus epithelium accounting for less than 1  % of all @entity1313 . These @entity5 are highly vascularized, and @entity5 resection is difficult, especially in small @entity1 , due to severe @entity954 . Preoperative embolization is helpful to reduce @entity954 , but it may not be possible in small @entity1 or if the @entity5 has no suitable feeding vessels for embolization. METHODS: We present the case of a 2-year-old @entity1 with a giant @entity2846 . An attempt of @entity5 resection was previously performed in another clinic, but the surgery was aborted due to massive @entity954 and only a biopsy was done. Angiography showed no suitable vessels for embolization. A new attempt of @entity5 removal was carried out, but again, severe @entity954 occurred and only a partial resection was possible. Intratumoral embolization with onyx through direct percutaneous puncture was performed. RESULTS: @entity5 removal was possible after two additional surgeries. Intraoperative @entity190 was 345  ml (first surgery = only partial removal), 250  ml (second procedure = 1/3 of @entity5 volume resected), and 250  ml (third surgery = total removal). The @entity1 presented no additional deficits. CONCLUSIONS: Intratumoral percutaneous embolization with onyx was very helpful in reducing @entity954 in this case. Safe radical @entity5 resection was possible. This technique may be useful for those surgeons dealing with highly vascularized @entity5 , especially in small @entity1 . No report of intratumoral embolization with onyx in cases of @entity5 could be found in the literature.
