Tuberculous pseudoaneurysm of the ascending aorta associated with intracranial tuberculoma

A tuberculous aneurysm is rare and fatal because it may lead to a rupture due to the forming of a pseudoaneurysm. A lesion is especially uncommon in the ascending aorta. We report an unusual case of tuberculous pseudoaneurysm of the ascending aorta which developed 7 months after the onset of multiple intracranial tuberculoma in a 59-year-old man. He was treated for multiple intracranial tuberculomas in another hospital because of headache and left homonymous hemianopia. The temporal intracranial tuberculomas were reduced after antituberculous drug administration. However, they enlarged again shortly thereafter. At that time, a pseudoaneurysm of the ascending aorta was found, so he was introduced to our department. Intensive antituberculous drugs were administered perioperatively and postoperatively. The intracranial tuberculoma was reduced preoperatively. After that, the ascending aorta was successfully replaced with a Dacron graft. A hole was noted in the back of the ascending aorta. Three years after the operation, no symptoms of recurrence have been recognized. A tuberculous pseudoaneurysm of the ascending aorta may easily cause systemic tuberculosis or rupture, therefore it should be treated as early as possible.
