Summary
A rare thalamic ependymoma caused recurrent subarachnoid hemorrhage in a 65-year-old woman. This case highlights the need for ongoing monitoring in patients with unexplained subarachnoid hemorrhage.
Area of Science:
- Neuro-oncology
- Neurology
- Neurosurgery
Background:
- Subarachnoid hemorrhage (SAH) is a critical neurological condition.
- The thalamus is a rare location for ependymomas.
- Identifying the source of SAH is crucial for management.
Purpose of the Study:
- To report the first case of thalamic ependymoma presenting as recurrent subarachnoid hemorrhage.
- To underscore the diagnostic challenges in cryptogenic SAH.
Main Methods:
- Case report of a 65-year-old female patient.
- Review of clinical presentation, diagnostic imaging (cerebral angiography), and histopathological findings.
- Discussion of the management and follow-up.
Main Results:
- A pathologically confirmed thalamic ependymoma was identified as the cause of recurrent SAH.
- Initial investigations, including cerebral angiography, failed to detect the tumor.
- Surgical resection and histopathological analysis confirmed the diagnosis.
Conclusions:
- Thalamic ependymoma is a rare but potential cause of recurrent subarachnoid hemorrhage.
- Periodic follow-up is essential for patients with SAH of undetermined etiology.
- Advanced imaging or re-investigation may be necessary when initial studies are inconclusive.
