A Case of Cerebral Embolism Associated with Calcified Amorphous Tumor: A Review of Cerebral Infarction Cases

Calcified amorphous tumor (CAT) is a non-neoplastic tumor composed of calcified nodules consisting of amorphous fibrous material, and it may eventually cause cerebral infarction (CI). We experienced a 67-year-old woman with CAT who had recurrent CI. After excision of the CAT, the CI did not show rec...

More Information
Summary:Calcified amorphous tumor (CAT) is a non-neoplastic tumor composed of calcified nodules consisting of amorphous fibrous material, and it may eventually cause cerebral infarction (CI). We experienced a 67-year-old woman with CAT who had recurrent CI. After excision of the CAT, the CI did not show recurrence. A review of previous papers on CI due to CAT in Pubmed revealed that 7 of 13 studies originated in Japan and that CI can occur even with small CAT. Surgical treatment is recommended to prevent CI recurrence, especially when CAT is accompanied by mitral annular calcification or has marked mobility.
