“…Benign and malignant neoplasms may occasionally present as a cystic mass within the orbit 116,117 . Cystic degeneration has been described in various rapidly growing orbital tumors, including squamous cell carcinoma (SCC), schwannoma, rhabdomyosarcoma, orbital metastases, and pleomorphic adenoma 117–124 .

[117][118][119][120][121][122][123][124] SCC can invade the orbit via perineural infiltration or arise from existing epithelial-lined cysts within the orbit, including dermoid, epidermoid, and lacrimal duct cysts. [124][125][126] In addition to the more common cystic neoplasms, case studies have described cystic morphology in primary orbital solitary fibrous tumor, meningioma, pilomatrixoma, and synovial sarcoma, among others.…”

Orbital cystic lesions encompass an array of congenital and acquired conditions with diverse aetiologies, ranging from benign, asymptomatic cysts to sight-threatening infectious or malignant disease. 1,2 They account for 14% to 21% of all orbital lesions. 2 Macroscopically, cystic lesions appear as saccular, fluid-filled structures encapsulated by a clearly demarcated wall. 1 They are commonly classified according to the cellular origin or etiology. 3,4 In a 2004 review of childhood orbital lesions, Shields and Shields 5 categorized cystic lesions by cellular origin (surface epithelium-derived, teratomatous, neural, secondary, infectious, and noncystic lesions with a cystic component). Another classification system, proposed by Kaufman et al, 6 in 1998, organizes cystic lesions by etiology; that is, congenital, acquired, or secondary cysts arising from adjacent structures. This review will expand upon the latter scheme, employing the following classifications; congenital (epithelial and nonepithelial), vascular, infectious and inflammatory, neoplastic, and miscellaneous. True cysts and cyst-like lesions, that is, those which appear cystic on imaging, will be covered, with a particular focus on the radiologic characteristics seen.Congenital lesions, such as dermoid cysts and orbital teratoma, generally present in infancy or early childhood and are usually benign; those which present later in life are more likely acquired, although lesions such as deep orbital dermoids may present in adulthood. [6][7][8] Clinical features vary depending on the size, depth, and aggressiveness of the underlying lesion. Superficial cysts often present with a painless,
