Abstract:
Meningiomas, originating from the meninges encasing the brain and spinal cord, are the most prevalent primary intracranial tumors, constituting around 40% of all such tumors. These tumors primarily manifest within the dura mater, the outermost meningeal layer, and occasionally in locations such as the ventricular system. However, the concurrent presence of dural and intraventricular meningiomas is exceedingly rare. It could be challenging to tell them apart from metastases. We present a case of a middle-aged female with chronic headaches, where magnetic resonance imaging (MRI) revealed two distinct supratentorial lesions, one dural and the other intraventricular. Surgical excision was successfully performed, and histopathological analysis confirmed the presence of meningiomas in both locations, and subsequent referral was made for comprehensive management, encompassing radiotherapy and chemotherapy. This case underscores the significance of advanced imaging modalities, particularly MRI, in diagnosing and assessing intricate brain tumors.
Insights
This case report details a rare instance of simultaneous dural and intraventricular meningiomas. Advanced magnetic resonance imaging (MRI) aided in diagnosing these challenging brain tumors.
Area of Science:
- Neuro-oncology
- Neurosurgery
- Radiology
Background:
- Meningiomas are the most common primary intracranial tumors, typically arising from the dura mater.
- While dural meningiomas are frequent, concurrent intraventricular meningiomas are exceptionally rare.
- Distinguishing these tumors from metastases can be diagnostically challenging.
Observation:
- A middle-aged female presented with chronic headaches.
- Magnetic resonance imaging (MRI) revealed two distinct supratentorial lesions: one dural and one intraventricular.
- The lesions were initially difficult to differentiate from metastatic disease.
Findings:
- Surgical excision was performed for both lesions.
- Histopathological analysis confirmed both lesions as meningiomas.
- The patient was referred for adjuvant radiotherapy and chemotherapy.
Implications:
- This case highlights the diagnostic utility of advanced imaging, particularly MRI, in complex intracranial tumors.
- It emphasizes the importance of considering rare presentations of common tumors.
- Comprehensive management including surgery, radiotherapy, and chemotherapy is crucial for such rare cases.
