Arabi M, Ibrahim M, Camelo-Piragua S, Shah G - Avicenna J Med (2013)

Bottom Line: These cysts are commonly encountered in the posterior fossa surrounding the brain stem structures.We present a case of pathologically proven supratentorial NE cyst that mimicked a hydatid cyst in its clinical presentation and imaging appearance.Including this pathology in the differential diagnosis of supratentorial cystic lesions is important due to the differences in medical and surgical management.

ABSTRACT
Neurenteric (NE) cysts are uncommon congenital cysts of endodermal origin. These cysts are commonly encountered in the posterior fossa surrounding the brain stem structures. We present a case of pathologically proven supratentorial NE cyst that mimicked a hydatid cyst in its clinical presentation and imaging appearance. Including this pathology in the differential diagnosis of supratentorial cystic lesions is important due to the differences in medical and surgical management.

Histopathology of the cyst. (a) H and E stain shows a cystic lesion, with a fibrous wall, lined by pseudostratified columnar epithelium. Note that some cells harbor large intracytoplasmic mucinous contents. (b) Alcian blue staining highlights the mucin content of some cells in blue. (c) Immunohistochemical stain for pan-cytokeratin demonstrates the epithelial origin of the cyst

(c) Immunohistochemical stain for pan-cytokeratin demonstrates the epithelial origin of the cyst

Mentions: Later, the patient underwent a stealth-guided left frontoparietal craniotomy for resection of cyst. The lesion was adherent to the cerebral pial surface and contained proteinaceous gelatinous yellowish discolored material. The lesion was irrigated several times with hypertonic saline to kill any hydatid ova. The patient's post-operative course was uncomplicated and albendazole was resumed. Histologically, the lesion showed a fibrous cyst wall lined by cuboidal to columnar, single to multilayered epithelium, which focally shows surface cilia and mucin production that is positive on alcian blue special histochemical stain. The cystic lining is immunoreactive for pan-cytokeratin and epithelial membrane antigen (EMA) and negative for glial fibrillary acidic protein (GFAP) and CK20 [Figure 5]. The histological features are consistent with an enterogenous/epithelial cyst. There is no evidence of hydatid cyst, scolex or other abnormal parasitic structure. Based on the final pathologic diagnosis, albendazole was discontinued.
