Enterogenous Cyst of the Orbital Apex and Superior Orbital Fissure

Intracranial neuroenteric cysts: A concise review including an illustrative patient

“…96 The second most common location of NC in the posterior fossa is the CPA (17-51%) 96 ; however, these lesions can also occur within the fourth ventricle. 6 Supratentorial NC are even rarer and have been reported in such locations as suprasellar, 103,112 parasellar, 22,127 along the optic nerve 80 or the oculomotor nerve, 68 superior orbital fissure, 128 or as intraparenchymal or durally based lesions, 21,105,110,115,129 intraventricular lesions, 6,71,89,90,111 and those at the craniocervical junction. 35,55,64 Given that NC can appear both histologically and radiologically similar to Rathke's cleft cyst and colloid cysts, location can provide an important distinguishing feature.…”

“…96 Avoidance of cyst fenestration, biopsy and partial wall resection have been suggested as management options due to the high risk of recurrence. 26,128 Wang et al have postulated that in subtotal resection of an NC, the residual cyst wall may be responsible for cyst recurrence. If the remnant walls are sufficient to overlap, the lesion may reform.…”

Orbital Conjunctival Cyst Associated With the Superior Rectus-Levator Muscles: A Clinicopathologic Study

“…18,19 Conjunctival cysts associated with superior rectuslevator muscles are not situated within the substance of the involved muscle, but rather are attached to some portion of the muscular epimyseal fascia. Radiographic studies in this case demonstrated that the cyst was actually lodged in the space between the superior rectus-levator muscles rather than attached to their edges.…”

“…8,9 The major types of cysts are congenital dermoids/epidermoids, 8 conjunctival cysts (congenital, idiopathic acquired, postsurgical and posttraumatic), 10 conjunctival dermoids, 11 lacrimal duct cysts (dacryops) of both the major and accessory lacrimal glands, 12,13 respiratory cysts (idiopathic and posttraumatic), [14][15][16] odontogenic cysts of oral mucosal embryonic origin that contain an abortive tooth, 17 and the rarest of all, the enterogeneous cyst of foregut endodermal origin. 6,18,19 Apocrine cysts can impinge on the anterior orbit from a gland located in the skin or caruncle, but technically they are not primary orbital conditions. 18,20,21 In this article, a cyst intimately associated with the superior rectus and levator muscles is described from the clinical, radiographic, histopathologic, and immunohistochemical perspectives for the first time and compared with similar earlier reports to identify common features of diagnostic value.…”

Supratentorial enterogenous cyst: A report of two cases and review of literature

“…Intracranial occurrence is distinctly rare, and often located in the infratentorial compartment. [2] Fewer than 16 cases in the supratentorial compartment location have been documented till date [3][4][5][6] [ Table 1]. We report two patients with supratentorial enterogenous cyst with special emphasis on management strategies.…”
