Summary
Granular cell tumors of the neurohypophysis are rare sellar lesions. Diagnosis requires histologic and immunohistochemical analysis, and early recognition aids patient outcomes.
Area of Science:
- Neuro-oncology
- Endocrinology
- Pathology
Background:
- Granular cell tumors (GCTs) are rare, benign neoplasms of pituicytes in the neurohypophysis.
- These tumors present diagnostic challenges due to their similarity to other sellar masses.
- GCTs often exhibit slow growth and nonspecific clinical and radiologic features.
