cysts of the brain-comprehensive magnetic resonance imaging.
In addition, as the enteric nervous system is not altered, the muscular component is likely to have played an important role, together with eosinophilic plexitis (a well-known cause of CIPO that might affect neuroenteric
functions) and further muscular impairment by eosinophilic infiltration (9).
CT scan/MRI of the chest is extremely valuable for accurate diagnosis, defines the anatomy, and rules out a list of differentials that include cystic hygroma, lymphangioma, neuroenteric
cyst, esophageal duplication cyst, and thymic cyst [1, 4, 9].
The differential diagnosis of retroperitoneal cystic masses includes arachnoid cyst, anterior sacral meningomyelocele (ASM), schwannoma, teratoma, hamartoma, neuroenteric
cyst, adrenal cyst, or primary mucinous cystic tumor of the retroperitoneum (1).
Foregut duplication cysts include bronchogenic, esophageal and neuroenteric
cysts, all arising from the embryonic primitive foregut.
Theories regarding the origin of enteric cysts point towards embryonic primitive foregut development anomalies.3 One of the most widely accepted theories about the origin of enteric cysts is split notochord syndrome which involves the persistence of neuroenteric
band.6 Veenklaas, in 1952, theorized that incomplete separation of ectoderm and notochord could eventually result in spinal anomalies.6 Perhaps this is why most enteric cysts are associated with vertebral anomalies.
The presacral mass can erode into the rectum leading to neuroenteric
fistulous communication resulting in fatal meningitis and large pneumocephalus.
In our case, the key imaging feature was the osseous stalk arising from the basisphenoid portion of the clivus, which is considered a morphologic hallmark of EP and is absent in other retroclival lesions, such as dermoids, epidermoids, arachnoid cysts, and neuroenteric
The gut is innervated by a number of events: neuroenteric
, endocrinological, cerebral, affective, dsthymic, and transferential" (10, 38).
Foregut duplication cysts are true mucus-filled cysts lined with a thin epithelial layer, arising from either bronchogenic, esophageal, or neuroenteric
precursor tissue; the cysts can be differentiated from one another histologically by the identification of the tissue-specific epithelial phenotype.
cysts are rare congenital anonalies, presenting in infancy or childhood.
