Endovascular treatment of primary infectious aneurysm in childhood: a case report.

Infectious aneurysms constitute 4% of all intracranial aneurysms. The microorganisms responsible are most commonly streptococcus viridans, staphylococcus aureus and combined bacterial infections. Nonetheless, cases with no reproduction in their cultures are rather frequent. A 6-year-old patient admitted with complaints of sudden headache, nausea, vomiting and high temperature. Intracerebral hematoma and saccular aneurysm located at the distal posterior cerebral artery were diagnosed as a result of the laboratory investigations and neuroradiological examinations. Infectious aneurysm was considered due to the clinical findings, morphology and location of the aneurysm. Although the causative microorganism was detected in blood culture, no focus could be detected. The aneurysm was hindered by endovascular intervention. In this manuscript, we discuss the infrequently seen childhood infectious aneurysm in the light of the pertinent literature.
