Summary
A rare intraventricular dysembryoplastic neuroepithelial tumor (DNT) was successfully removed from a patient with intractable epilepsy. Surgical resection led to seizure control, highlighting the importance of recognizing these rare DNT presentations.
Area of Science:
- Neuro-oncology
- Epileptology
- Neurosurgery
Background:
- Dysembryoplastic neuroepithelial tumors (DNTs) commonly occur in the supratentorial cortex, particularly the temporal lobe.
- Intraventricular DNTs represent an exceptionally rare subtype of this brain tumor.
Observation:
- A 30-year-old female presented with refractory epileptic seizures unresponsive to antiepileptic drugs.
- Neuroimaging revealed a lesion within the occipital horn of the right lateral ventricle.
Findings:
- The intraventricular lesion was completely resected and diagnosed as a DNT via histopathological and immunohistochemical analysis.
- Post-surgery, the patient experienced significant seizure control, with no evidence of residual or recurrent tumor on follow-up imaging.
Implications:
- Complete surgical excision is curative for DNTs, obviating the need for adjuvant radiotherapy or chemotherapy.
- Accurate identification of intraventricular DNTs is crucial for effective surgical management and patient outcomes.
