Background: Glioependymal cysts (GECs) are rare benign lesions that can be found anywhere along the neuroaxis, with most of the reports denoting supratentorial location. Here, we introduce a rare case of successfully treated glioependymal cysts lying in an uncommon location, namely medulla oblongata. Case Description: A 69-year-old lady presented with progressive unsteadiness and swallowing disturbances, and brain magnetic resonance imaging showed a dorsally located lesion within the medulla oblongata; based on the presentation and radiological features, surgical intervention was deemed mandatory. The suboccipital midline approach was used to perform marsupialization of the cyst with shunting through a syringosubarachnoid shunt to prevent future recurrence, and the patient outcome was improved. Conclusion: Medulla Oblongata’s location for glioependymal cysts proposed unique diagnostic and operative challenges that may require highlighting for practicing neurosurgeons.

“…GECs are benign intracranial cysts that have rarely been reported in the literature, 21,22,[24][25][26][27][28][29][30] especially concerning cysts located in the interhemispheric space, which only account for 11.1% of all GEC cases. 8 We are convinced that this report would provide valuable information regarding intracranial cysts.…”

A large interhemispheric glioependymal cyst associated with partial defect of the corpus callosum in an elderly man

Interhemispheric cysts are congenital, and usually present symptoms during childhood. However, they are occasionally detected in adults. These cystic lesions are sometimes associated with defects of the corpus callosum. Although defects of the corpus callosum by themselves do not present clinical symptoms, they are often accompanied by other brain malformations. A man in his late 60s was found dead at the scene of a fire. At autopsy, his brain weighed 1223 g and had a large interhemispheric cyst, measuring 5.5 × 4.5 × 4.0 cm in size. The cyst contained clear fluid but was not connected to the ventricular system. On slices of the cerebrum, the corpus callosum did not connect the right and left cerebral hemispheres, and the right lateral ventricle was dilated. By the existence of the cyst, compressed by the cyst, the hemispheres were displaced on either side. Histologically, the cerebral parenchyma around the cyst was slightly edematous but structurally normal. Immunohistochemically, both glial fibrillary acidic protein and podoplanin were expressed in the cystic components. Thus, the cystic lesion was diagnosed as a glioependymal cyst. In this case, because the cyst was located at the interhemispheric space between the right and left frontal lobes, the individual experienced no obvious symptoms, despite its large size. The individual's brain malformations included the partial defect of the corpus callosum and the cyst. The dilation of the right lateral ventricle was considered to result from the location of the cyst. Under the influence of the cyst, the third ventricle was displaced downward, and one or both of the interventricular foramen were obstructed. The decedent had burns over his whole body. Burns to the epiglottis and soot in the airway were also observed. Volatile hydrocarbons, such as benzene and styrene, were detected in the blood. The percentage of carboxyhemoglobin levels in a total of hemoglobin levels were 19-25%. Therefore, the individual's cause of death was established as death by fire.

“…As stated by Friede and Yasargil [8], Zehnder was the irst author to describe this entity in 1938. Currently, our search on PubMed ind approximately only 40 cases reported in literature [1,3,[6][7][8][9][10][11][12] (Table 1) cysts that arise from ectopic rests of primitive neuroglial tissue, and hence, can arise anywhere in the neuraxis but are often located in the central white matter of the temporoparietal and frontal lobes in juxtaventricular regions [2,5,12]. In contrast, there were only four patients with cysts in the occipital lobe, one of whom was our patient.…”

Intraparenchymal cysts without communication to the ventricles or the subarachnoid space are named ependymal or epithelial cysts. The estimated ratio of their incidence compared with arachnoid cysts is 1:10. Neurologic defi cit can occur when the cyst exerts mass effect on its surroundings. We report a case of cerebral ependymal cyst in a 75-year-old lady who presented with history of headache, vomiting and left incomplete homonymous hemianopsia. Neuroimaging studies showed a large right occipital cyst. She underwent the neurosurgical procedure of marsupialization. Histologic fi ndings and the immunophenotype was consistent with a diagnosis of ependymal cyst. The patient made an excellent recovery after the procedure.
