Summary
A rare suprasellar tumor caused seizures and neurological issues in a 58-year-old man. Surgical removal was challenging due to the tumor
Area of Science:
- Neuro-oncology
- Neurology
- Neurosurgery
Background:
- A 58-year-old male presented with generalized convulsions.
- Initial CT revealed a calcified low-density mass in the right hypothalamus.
Observation:
- Multiple high-intensity lesions in the subarachnoid space were noted on T1-weighted MRI.
- New lesions appeared in the bilateral anterior horns, and third ventricle dilation was observed.
- MRI demonstrated enhancement around the tumor and lateral ventricles, with aqueductal stenosis.
Findings:
- Surgical exploration revealed a yellowish suprasellar tumor with hair and soft tissue, adhering to the internal carotid artery.
- Thickened arachnoids and floating lipid droplets were present in the subarachnoid space.
- Partial tumor removal was performed due to severe adhesion to perforating vessels.
Implications:
- This case highlights the complex presentation and surgical challenges of suprasellar tumors.
- Understanding the tumor's characteristics and adherence is crucial for surgical planning and patient outcomes.
- Transient diabetes insipidus was a postoperative complication, emphasizing the need for vigilant monitoring.
