“…Clinical signs most commonly regress after surgery. Although a radical resection prevents recurrence, considering the fact that a thin capsule may firmly adhere to the brainstem, it is not always possible to completely resect the capsule without any neurological deficit, especially in PCF [4][5][6]17]. Kozak et al [4] described a case series operated in the period from 2010 to 2018.…”

Neurenteric cysts (NCs) are rare congenital lesions that are thought to result from the persistence of the neurenteric canal connecting primitive gut and neural tube. Despite the congenital nature, NCs can be diagnosed at any age and at a similar frequency in women and men. To our knowledge, 140 intracranial NCs, confirmed by histology, including the patient presented in this review, have been reported since 1952. Parenchymal NCs are extremely rare, and there are no publications describing the intra-axial NCs of the brainstem at the moment.A 19-year-old female presented to the clinic with the following complaints: moderate dysphagia (two to three times per day) for and liquids and solids, dysphonia, vertigo, spontaneous nystagmus, imbalance, and numbness in the left side of the body, including the face. The magnetic resonance imaging (MRI) of the brain showed a well-defined lesion centered in the medulla. The patient underwent a small right-sided keyhole retro-sigmoid craniotomy. Just under the sulcus, a cyst containing pathological amorphous gray-yellow liquid was evacuated. Accessible parts of the capsule were resected without brain injury. Residual particles of the capsule were coagulated.Two months after the operation, the patient presented with similar symptoms. We used the previous craniotomy during the second surgery. After the evacuation of the cyst, a silicone stent was set for connecting with the cerebellopontine cistern and preventing new synechiae formation. As surely as after the first surgery, all neurological symptoms gradually regressed. In two months after surgery, deglutition and sensations recovered, and hemiparesis and imbalance decreased. Postoperative MRI examination two months after surgery showed no evidence of cyst recurrence.Intra-axial NCs are a rare group of congenital pathological lesions with a favorable prognosis. There are no publications of brainstem NCs with intra-axial localization to date. The treatment of choice in this group of patients is complete microsurgical excision followed by long-term observation.

“…Most of the intracranial NCs localize in PCF in basal cysterns, craniocervical junction or IV ventricle. Parenchymal localization is extremely rare [5][6][7][8]17]. MRI examination is a method of choice in the diagnostic algorithm of NC but its characteristics can be variable.…”

“…MRI examination is a method of choice in the diagnostic algorithm of NC but its characteristics can be variable. It shows well-demarcated lesions iso-or tightly hypointense in T1 and hyperintense in T2-weighted sequences and FLAIR [5,6,8,17,18]. NCs usually demonstrate no contrast enhancement but Prasad, et al reported mild posterior rim enhancement that can be explained by chronic inflammatory changes due to repeated cyst rupture in their view [19].…”

“…Clinical signs regress after surgery in large part. Although radical resection will prevent recurrence, in view of the very thin firmly adherent capsule to the brainstem, it is not always possible to do complete resection capsule without any neurological deficits, especially in PCF [4,5,8,17].…”

“…Intracranial locations are predominantly infratentorial anterior to the brainstem, at the cerebellopontine angle and to a lesser extent within the cisterna magna and the fourth ventricle. Parenchymal NCs are extremely rare [5][6][7][8]17] and there are not any publications describing the intra-axial NECs of brainstem at the moment.…”
