Pleomorphic adenoma is the most common benign epithelial tumour of the lacrimal gland. It is composed of both epithelial and mesenchymal elements; the latter mainly consists of myxoid stroma. Typically, on imaging, it presents as a well-defined, solid mass in lacrimal gland fossa with bony remodeling. Internal architecture of the tumour may be heterogeneous as the myxoid stroma within the tumour can be seen as hypodense areas. Presence of cystic spaces within pleomorphic adenoma of the lacrimal gland is extremely rare and can lead to misdiagnosis.
