Summary
A rare thalamic cavernous malformation was successfully removed using a contralateral surgical approach, leading to symptom recovery. This technique minimized brain retraction and injury for a favorable outcome.
Area of Science:
- Neurosurgery
- Neuropathology
Background:
- Thalamic lesions pose surgical challenges due to surrounding neurovascular structures.
- Cavernous malformations are rare vascular anomalies in the brain.
Observation:
- A 42-year-old male presented with headache and right hemiparesis.
- Imaging revealed a cystic mass with a calcified mural nodule in the left thalamus.
Findings:
- The thalamic mass was surgically removed via a contralateral interhemispheric transcallosal transchoroidal approach.
- Pathological diagnosis confirmed a cavernous malformation.
- Postoperative recovery included resolution of hemiparesis and persistent thalamic pain syndrome.
Implications:
- The contralateral surgical approach offers a less invasive option for thalamic lesion resection.
- This case highlights a favorable outcome for thalamic cavernous malformations treated with this technique.
- Minimizing brain retraction and parenchymal injury is crucial in thalamic surgery.
