Summary
Multiple deep-seated cavernomas in the brain are rare. This case highlights the complex management of these lesions, emphasizing individualized treatment based on patient factors and lesion characteristics.
Area of Science:
- Neurosurgery
- Neurology
- Vascular Malformations
Background:
- Cavernomas (cerebral cavernous malformations) are uncommon, particularly in deep brain structures like the third ventricle, hypothalamus, and thalamus.
- Multiple cavernomas in these specific locations present a significant management challenge.
Observation:
- A 62-year-old woman presented with gait instability and leg weakness due to three cavernomas: one in the third ventricle floor, one in the hypothalamus, and one in the left thalamus.
- Surgical excision of the third ventricle cavernoma via a transcortical, transventricular approach confirmed the diagnosis.
- Post-operative complications included a left thalamic hemorrhage, leading to right hemiparesis and altered consciousness.
Findings:
- The patient's condition improved with conservative management, regaining ambulation with support seven months post-surgery.
- Magnetic resonance imaging (MRI) was crucial in identifying the suspected cavernomas in the hypothalamus and thalamus.
Implications:
- Management of multiple, deep-seated cavernomas necessitates careful consideration of clinical presentation, precise location, tumor size, and bleeding history.
- This case underscores the need for tailored surgical and conservative strategies for rare intracranial cavernomas.
