Summary
Intraventricular schwannomas are extremely rare brain tumors. Complete surgical excision offers a good prognosis for these benign neoplasms, highlighting the importance of accurate diagnosis.
Area of Science:
- Neuro-oncology
- Neurosurgery
Background:
- Intraventricular schwannomas are exceptionally rare, with fewer than 20 reported cases.
- The precise origin of intraventricular schwannomas remains debated in medical literature.
Observation:
- A case of a supratentorial intraventricular schwannoma in the left lateral ventricle is presented.
- The patient, a 34-year-old male, experienced focal motor seizures and right lower extremity weakness.
- Brain MRI revealed a heterogeneous enhancing mass with vasogenic edema.
Findings:
- Surgical excision was performed using neuronavigational guidance to protect the motor cortex.
- The tumor was found to originate from the ependymal layer, extending into the lateral ventricle.
- Complete tumor resection was successfully achieved.
Implications:
- Intraventricular schwannomas are benign and amenable to complete surgical removal.
- Successful excision leads to a favorable prognosis, often precluding the need for adjuvant therapies.
- Distinguishing these tumors from more malignant neoplasms is crucial for appropriate patient management.
