A patient, a 72-year-old male, with a thymic carcinoma spreading to the extrathoracic region, is reported. he had undergone a thoracotomy and received radiation-and chemotherapy. Four months later, the patient was noticed to have a mild left sided hemiparesis. Further evaluations revealed metastasis of thymic carcinoma to the bone and intracranial region. Surgical treatment for intracranial lesion was performed, and the patient's left sided hemiparesis was cleared. Thymic carcinoma is uncommon, and its intracranial metastasis is rare. We found 27 previous reports of intracranial metastasis of thymic carcinoma and malignant thymoma. This time, we report a case of thymic carcinoma with intracranial (falx) metastasis, and discuss the concept of thymic carcinoma and thymomas in a review of the literature.
