Which of the following is the most common benign primary intraorbital tumour in adults?
- A Optic nerve glioma
- B Meningioma
- C Pleomorphic adenoma of the lacrimal gland
- D Cavernous haemangioma ✓
Correct answer: D. Cavernous haemangioma
Explanation
Cavernous haemangioma is the commonest benign orbital tumour of adulthood, typically presenting as a slowly progressive axial proptosis in middle-aged women. Optic nerve glioma occurs mainly in children and is associated with neurofibromatosis type 1. Pleomorphic adenoma arises in the lacrimal gland fossa and produces inferomedial rather than axial displacement, which distinguishes it clinically.
