From: Surgical resection of unilateral thalamic tumors in adults: approaches and outcomes
a Different surgical approaches to thalamic tumors arising from junction of pulvinar thalamus and cerebral peduncle were showed in the diagram. b An astrocytoma was removed subtotally via a transtemporal approach. The tumor arose from the junction of thalamus and cerebral peduncle and extended to both sides equally, and both parts were well exposed via the transtemporal approach. c The inferior part of another astrocytoma was well exposed and removed via a subtemporal approach. The postoperative MR image shows that some residual tumor was still present in the thalamic region
