Multiple cerebral infarctions due to calcified amorphous tumor growing rapidly from an antecedent infection and decreasing rapidly by detachment of fibrin and antithrombotic drugs: a case report.

Inflammation from an antecedent infection can cause CAT to grow rapidly. Fibrous tissue including fibrin may attach to the surface of CAT, resulting in multiple cerebral infarctions. Fibrous tissue may detach and disappear by antithrombotic drugs, leading to a rapid diminishment of CAT in size.
