Eosinophils were Significantly Elevated in the Chronic Subdural Hematoma Fluids: Two Case Reports
Insights
Eosinophils increase in chronic subdural hematoma (CSDH) drainage fluid, though their role remains unclear. Further research on eosinophil distribution in CSDH patients is crucial for treatment and recurrence prediction.
Area of Science:
- Neurosurgery
- Hematology
Background:
- Chronic subdural hematoma (CSDH) is a common neurosurgical condition in the elderly, often treated with burr-hole drainage.
- Microscopic examination of drainage fluid is a standard laboratory analysis for CSDH patients.
Observation:
- Cranial MRI confirmed CSDH in patients.
- Routine blood tests showed no significant abnormalities.
- Postoperative drainage fluid analysis revealed a notable increase in eosinophils.
Findings:
- A significant proportion of eosinophils were observed in the postoperative drainage fluid of CSDH patients.
- No concurrent abnormalities were detected in peripheral blood tests.
Implications:
- The precise mechanism and clinical significance of eosinophil infiltration in CSDH are currently unknown.
- Further investigation into eosinophil and chemokine distribution in CSDH patients' blood and drainage fluid is warranted.
- Understanding eosinophil roles may improve CSDH treatment strategies and recurrence prediction.
Background:
Chronic subdural hematoma (CSDH) is a type of spontaneous or post-traumatic intracranial hemorrhage located between the dura mater and arachnoid membrane. It is a neurosurgical disease that often occurs in the elderly. Burr-hole drainage is the main treatment method, and smear microscopic examination of the drainage fluid is a common laboratory method.
Methods:
A cranial magnetic resonance imaging (MRI) was performed, then blood and drainage fluid from patients with CSDH was collected and sent to the laboratory for routine laboratory tests.
Results:
Both patients' cranial MRI indicated CSDH, while no significant abnormalities were found in blood-related tests. Microscopic examination of postoperative drainage fluid revealed a significantly increased proportion of eosinophils.
Conclusions:
It is found that the mechanism of eosinophil infiltration in CSDH and its significance for patients are still unclear by combining the cases and relevant literatures. Further research is needed to study the distribution and changes of eosinophils and related chemokines in the peripheral blood and postoperative drainage fluid from CSDH patients, which is of great significance for the treatment and recurrence prediction of CSDH patients.
