Syndrome of the trigone occurs when intracranial tumors that arise in the trigone of the lateral ventricle present with a distinctive constellation of signs and symptoms due to compression of the posterior limb of the internal capsule and the adjacent white matter of the parietal and posterior frontal cortex.
Clinical presentation
Clinically this manifests as:
- contralateral limb weakness
- contralateral homonymous hemianopsia
- receptive dysphasia
If the mass grows downward far enough to compress the superior cerebellar peduncle then ipsilateral cerebellar signs may also be present. Non-specific symptoms may of course also co-exist, such as headaches, seizures and cognitive changes.
