Presence of a cyst or a cystic component in an intraorbital mass often narrows the list of differential diagnoses to specific entities. Such a lesion in the orbit may arise from structures within the orbit, globe, and lacrimal system or from neighboring paranasal sinuses or meninges. Common congenital and developmental lesions encountered within the orbit include dermoids and epidermoids, and infrequently coloboma. Parasitic cysts (cysticercus), orbital abscess, mucocele, and vascular lesions are the most common acquired pathologies giving rise to fluid-containing lesions within the orbit. The role of a radiologist is crucial in expediting the diagnosis of orbital lesions with the help of characteristic imaging features on ultrasound, computed tomography, or magnetic resonance imaging. It also helps in identifying complications in others where formulation of an early and effective management strategy is vital for preserving vision.
