脳梗塞を発症した乳頭状線維弾性腫

Surgical Experience of Papillary Fibroelastoma Revealed by Cerebral Infarction

乳頭状線維弾性腫（PFE）は，比較的まれな原発性心臓腫瘍の中では粘液腫に次いで発生頻度が高い1）良性腫瘍である．PFEは致死的塞栓症を引き起こすことがあり，診断後はすみやかな外科的摘出が推奨されている．脳梗塞を発症し，精査の結果PFEと診断された3例を経験したので，報告する．

Primary cardiac tumors are relatively rare. Among them, papillary fibroelastoma （PFE） is the 2nd most common benign cardiac tumor after myxoma. However, despite its benign status, PFE may trigger fatal embolic events in some cases. Therefore, once PFE is diagnosed, immediate surgical resection of the tumor is recommended. We report our experience of 3 patients with cerebral infarction that were diagnosed as having PFE. All cases were complicated with cerebral infarction probably originating from a tumor embolus or thrombus. For that reason, after the tumor had been detected, urgent surgical resection of the tumor was considered to be necessary. Given the generally good postoperative outcomes, simple resection of the tumor while preserving valve function is considered sufficient to achieve a favorable outcome.
