Abstract:
Background: Non traumatic subdural hematomas are rare, especially those associated with intracranial meningiomas. Among the most common meningiomas associated with spontaneous bleeding are angioblastic and malignant meningioma variants. The pathophysiological mechanisms of this association are not yet fully understood. The association of chronic subdural hematoma with microcystic meningioma histological subtype has not yet been described in the literature. Case report: The authors present a case report of a patient with a spontaneous non traumatic chronic subdural hematoma associated with a microcystic subtype grade I meningioma of the parietal convexity. Epidemiological, etiology, natural history, pathophysiology, risk factors of bleeding and treatment options are reviewed. Conclusion: Spontaneous subdural hematomas associated with meningiomas are rare, specially related to the microcystic variant of meningioma. Careful pre-operative consideration of specific anatomy and pathophysiological features are paramount to their full treatment.
Insights
Spontaneous non-traumatic subdural hematomas are rare, particularly when linked to microcystic meningiomas. This case highlights the importance of considering this rare association for effective patient treatment.
Area of Science:
- Neuroscience
- Oncology
- Neurosurgery
Background:
- Non-traumatic subdural hematomas (SDH) are uncommon neurological events.
- Intracranial meningiomas, particularly angioblastic and malignant types, are occasionally associated with spontaneous bleeding.
- The pathophysiological links between meningiomas and SDH remain incompletely understood.
Observation:
- A rare case of spontaneous non-traumatic chronic subdural hematoma is presented.
- The hematoma was associated with a microcystic subtype Grade I meningioma of the parietal convexity.
- This specific association (chronic SDH with microcystic meningioma) has not been previously documented in medical literature.
Findings:
- The study reviews epidemiological data, etiology, natural history, pathophysiology, and bleeding risk factors for SDH associated with meningiomas.
- Treatment strategies for this rare condition are discussed.
- The microcystic meningioma subtype is identified as a potentially overlooked cause of spontaneous SDH.
Implications:
- Spontaneous SDH linked to meningiomas, especially the microcystic variant, represents a rare clinical presentation.
- Thorough pre-operative evaluation considering the unique anatomical and pathophysiological aspects is crucial for optimal management.
- This case expands the understanding of meningioma-associated bleeding complications.
