Abstract:
In a retrospective study of 125 case reports of intracranial supratentorial meningiomas, the authors have isolated 10 patients whose meningioma had been revealed by pseudo-vascular syndromes. Mean age and sex ratio were the same in this group of patients as in those patients whose meningioma had been more classically disclosed by an epileptic seizure, a motor or a progressive sensorimotor deficit. The site of the tumour exerted an influence on the nature of clinical manifestations. There was no correlation between the size of the tumour and the transient or prolonged course of the pseudo-vascular syndrome. The pathogenesis of these disorders is discussed.
Insights
Intracranial supratentorial meningiomas can present as pseudo-vascular syndromes, mimicking stroke. Tumor location influences symptoms, but size does not correlate with syndrome duration in these rare cases.
Area of Science:
- Neurology
- Neurosurgery
- Oncology
Context:
- Intracranial supratentorial meningiomas are tumors arising from the meninges.
- Pseudo-vascular syndromes are neurological deficits that mimic cerebrovascular events.
Purpose:
- To investigate the clinical presentation and characteristics of intracranial supratentorial meningiomas presenting as pseudo-vascular syndromes.
Summary:
- A retrospective review of 125 meningioma cases identified 10 presenting with pseudo-vascular syndromes.
- Clinical manifestations varied based on tumor location, not tumor size.
- Demographics (age, sex ratio) were similar to patients with classic meningioma symptoms like seizures or deficits.
Impact:
- Highlights an uncommon presentation of meningiomas, aiding in differential diagnosis for stroke-like symptoms.
- Emphasizes the importance of considering meningiomas in the evaluation of pseudo-vascular syndromes.
- Contributes to understanding the varied clinical spectrum of supratentorial meningiomas.
