title: [A case of intra- and extracranially extensive metastatic brain tumor of tracheal cancer origin].
abstract: The authors report a case of metastatic brain tumor of tracheal cancer origin, itself a rare condition. A 55-year-old man was admitted with complaints of headache, atonic seizure of left lower limb and right temporal swelling. On admission, the patient had left recurrent nerve palsy. CT scan displayed right temporal bone destruction and ring-enhanced mass. MRI disclosed that the mass contained an inner necrotic region and a perifocal edema. Right common carotid angiogram revealed that the tumor was fed only by narrowed vessels of the middle meningeal artery. Subtotal removal of the tumor was performed, and histological examination revealed cranial metastasis of tracheal squamous cell carcinoma. Postoperative course was uneventful, and the patient underwent medical treatment for the primary lesion before post-operative brain-irradiation.
