Surgical Management and Outcome of a Ruptured Aseptic Mycotic Cerebral Aneurysm: A Case Report

Background: Mycotic aneurysms are a rare subset of intracranial aneurysms caused by bacterial, viral or fungal sources. Rupture of an intracranial mycotic aneurysm is a life-threatening event untreated with a mortality range up to 80%. Case description: Here, we report the case of a 21-year-old second year female medical student who suffered from a ruptured mycotic aneurysm of the middle cerebral artery with subarachnoid haemorrhage. After surgical resection of the aneurysm, intensive monitoring and treatment of cerebral vasospasm were performed. Further diagnostics for the focus of infection, including laboratory parameters, transoesophageal echocardiography and otolaryngoscopic diagnostic, showed normal findings without any sign of endocarditis, vasculitis or otolaryngitis. After 3 weeks, the patient was discharged in a very well condition. Conclusion: Aseptic mycotic aneurysm is a rare subtype with posing significant therapeutic challenge. Surgical resection of those aneurysms might be safe and effective treatment
