Intracranial mycotic aneurysm associated with transsphenoidal surgery to the pituitary adenoma
1Department of Neurosurgery, School of Medicine, Kanazawa University, Japan.
Abstract:
A case is reported in which a mycotic aneurysm of the supraclinoidal portion of the internal carotid artery formed as the result of suprasellar infection following transsphenoidal surgery. The source of infection was thought to be a maxillary sinusitis. The aneurysm was treated with systemic antibiotic therapy and disappeared 4 months after the operation. Repeated angiography showed the whole course from the formation to the disappearance of the aneurysm and was valuable in the treatment of intracranial mycotic aneurysms.
Insights
A rare case of a mycotic aneurysm in the internal carotid artery, stemming from a sinus infection after surgery, resolved with antibiotics alone. Angiography tracked its formation and disappearance, proving valuable for managing such intracranial aneurysms.
Area of Science:
- Neurology
- Vascular Surgery
- Infectious Diseases
Background:
- Mycotic aneurysms are rare but serious complications.
- Transsphenoidal surgery can lead to intracranial infections.
- Maxillary sinusitis is a potential source of infection.
Observation:
- A mycotic aneurysm formed in the supraclinoidal internal carotid artery after transsphenoidal surgery.
- The infection likely originated from a maxillary sinusitis.
- The aneurysm was visualized throughout its course via repeated angiography.
Findings:
- Systemic antibiotic therapy led to the complete resolution of the mycotic aneurysm.
- The aneurysm disappeared within 4 months of treatment.
- Angiography was instrumental in monitoring the aneurysm's evolution and treatment efficacy.
Implications:
- This case highlights the successful non-surgical management of a mycotic aneurysm.
- It underscores the importance of considering sinus infections as a source for intracranial complications post-surgery.
- Serial angiography is a valuable tool for managing intracranial mycotic aneurysms.
