[Mycotic aneurysm of the middle cerebral artery in echinococcal infestation]
Abstract:
Cerebral mycotic aneurysms, which are found primarily on the branches of the middle cerebral artery, may be the cause of either an intracranial haemorrhage or an ischaemic insult. Of the intracerebral haemorrhages reported by Russell, 6% were caused by mycotic aneurysms (Jellinger, 1979). A case of mycotic aneurysm of the middle cerebral artery with an intracerebral haemorrhage in a patient with echinococcal cysts in the lungs, pericardium and left kidney is reported and discussed. Two weeks postoperatively the patient deteriorated neurologically and a computer tomogram of the brain showed multiple intracerebral hemorrhages. Suspected is either rupture of the pericardial echinococcus cysts with subsequent haematogenous spread or the presence of multiple intracranial mycotic aneurysms, manifesting themselves as multiple intracranial haemorrhages.
Insights
Mycotic aneurysms, fungal infections affecting brain arteries, can cause severe bleeding. This case highlights a rare instance of multiple cerebral aneurysms linked to echinococcal cysts, leading to brain hemorrhages.
Area of Science:
- Neurology
- Infectious Diseases
- Radiology
Background:
- Cerebral mycotic aneurysms commonly affect the middle cerebral artery.
- They are a significant cause of intracranial hemorrhage, accounting for 6% of cases.
- Echinococcal cysts can lead to systemic infections.
Observation:
- A patient with echinococcal cysts in lungs, pericardium, and kidney developed neurological deterioration post-operatively.
- A brain CT scan revealed multiple intracranial hemorrhages.
- The hemorrhages were suspected to be caused by ruptured echinococcal cysts or multiple mycotic aneurysms.
Findings:
- The case presents a rare association between echinococcal disease and the development of multiple intracranial mycotic aneurysms.
- Neurological decline correlated with the appearance of multiple intracerebral hemorrhages.
Implications:
- This case underscores the importance of considering disseminated infections in patients presenting with neurological symptoms.
- Early diagnosis and treatment of mycotic aneurysms are crucial to prevent severe outcomes.
- Further research is needed to understand the link between echinococcosis and cerebral aneurysm formation.
