Delayed cerebral metastases after left-atrial myxoma resection in a child

Atrial myxoma in children is rare, with vision loss and cerebral metastasis seldom reported. We present the case of a 12-year-old girl who experienced sudden vision loss and acute infarction, with a left atrial myxoma identified and surgically resected. One year later, she was readmitted with severe neurological symptoms. Imaging revealed multiple hypometabolic brain lesions, which were confirmed as metastatic myxoma through surgical resection and pathology. This case underscores the critical need for long-term follow-up in patients with cardiac myxoma to monitor potential delayed neurological complications.
