Thalamomesencephalic cavernous malformations are deep lesions located near sensory, motor, and visual pathways as well as the deep venous system, making surgical treatment challenging. Careful corridor selection is essential to minimize injury to eloquent structures. OBSERVATIONS: A 35-year-old man presented with progressive left facial and hemibody numbness and low-frequency tinnitus....

No actionable change for audiologists — this is a neurosurgical case report describing a rare brain lesion resection technique with no direct relevance to audiology clinical practice.
While peripheral to audiology, thalamomesencephalic lesions can cause auditory pathway disruption; this case report adds to the neurosurgical literature on approaches that may occasionally be relevant when managing patients with central hearing complaints.
- 01Single case report of thalamomesencephalic cavernous malformation resected via retrosigmoid supracerebellar transtentorial approach.
- 02Illustrative neurosurgical case with no direct audiology or hearing-device focus.
- 03Thalamomesencephalic region can affect central auditory pathways when lesions are present.
- 04Surgical approach described is highly specialized and rarely encountered outside neurosurgery.
- 05Minimal relevance to routine audiology or hearing-aid practice.
The retrosigmoid supracerebellar transtentorial approach is a viable surgical route for resecting thalamomesencephalic cavernous malformations.
