[A case of bacterial aneurysm following Hardy's operation].
Intracranial mycotic aneurysm of extravascular origin is reported. A 64 year-old male developed headache and visual disturbance. Computed Tomography (CT) revealed high density mass lesion with contrast enhancement in the intra- and suprasellar lesion. He was then admitted to our hospital under the diagnosis of pituitary adenoma. But he suddenly complained of headache and loss of vision during hospitalization. An emergency operation using the transsphenoidal approach was performed. The pathological diagnosis was craniopharyngioma. Postoperative radiation therapy was carried out using a tumor dose of 50Gy. Two months after the operation, he suffered from rhinorrhea and high fever. He was admitted again and treated with high doses of antibiotics. Two weeks after admission, he suddenly lost consciousness. A CT scan revealed an aneurysm of the anterior temporal artery. Immediately, removal of the hematoma and resection of the aneurysm were performed. Microscopic examination showed that inflammatory cells had infiltrated the aneurysmal wall, and lymphocytes and plasma cells had gathered around the microabscess. This rare case is discussed with other related cases in the literature.
