“…24 Endoscopic excision of IVNCC is a relatively new technique and has been increasingly practiced by various neurosurgeons. [25][26][27][28][29]31,36,37 Because of its minimally invasive nature, the risk of parenchymal injury is much less. Moreover, endoscopy allows a quick and easy approach to single or multiple cysts located within the ventricles.…”

“…Neuroendoscopy, however, is not a risk-free procedure. The risks of neuroendoscopy include hemorrhage, with the inherent difficulty of controlling the bleeding, infection, and raised intracranial pressure from too much irrigation without proper venting 13,15 .…”

Arachnoid cysts of the posterior fossa represent a rare group of central nervous system lesions. Quadrigeminal cistern cysts, specifically, are unusual lesions, with only 79 cases described in the English literature [1][2][3][4][5][6][7][8] . Classical treatment of such lesions consists of craniectomy and fenestration of the lesion or cystoperitoneal shunting. Neuroendoscopy represents a new effective minimally invasive approach for such lesions.We report the case of a two year old boy who presented a quadrigeminal cyst arachnoid cyst which was successfully treated by neuroendoscopy in our department. CASEA two-year-old boy, presented to our department with one month history of daily headaches, vomiting and gait instability. There was no report of recent associated infections, previous history of any classical childhood viral infection or alterations of psychomotor development. The exam at admission revealed a hypoactive child, obvious macrocrania and gait instability associated with lower limbs hypertonia. There was no papilloedema. There were no cranial nerves or sensitive alterations. Analysis of the cephalic perimeter growth curve showed mild upward deviation since the initial months of life. Computed tomography (CT) scan demonstrated supratentorial hydrocephalus associated with a cystic lesion in the posterior fossa. Magnetic resonance image (MRI) demonstarted enlargement of the supratentorial ventricular system secondary to a large quadrigeminal cistern arachnoid cyst compressing the brainstem, cerebellum, aqueduct of Sylvius and fourth ventricle (Fig 1). A ventriculo-peritoneal shunt was inserted at this time, with regression of the symptoms.Seven months later, the patient returned to our department with history of new episodes of headache and vomiting. A new MRI revealed persistence of the arachnoid cyst. It was decided to perform endoscopic fenestration of the cyst and third ventriculostomy for treatment of the hydrocephalus.Informed consent was obtained from the family and the patient underwent the surgical procedure. A paramedian incision was performed overlying the right coronal suture, 2.5 cm off the midline. Then a 14-mm burr hole was created and the dura-mater opened. After navigating through the right lateral ventricle and third ventricle, the arachnoid cyst was reached and cysto-ventricle shunting was realized. This was followed by a third ventriculostomy. There were no complications during the surgery. The patient presented no symptoms at time of discharge (Fig 2A).At one year follow-up, the patient was asymptomatic. Neurological examination was unremarkable (Fig 2B).

“…There have been recent reports of septostomies and 3rd ventriculostomies in conjunction with cyst removal associated with good results [18]. Other reports have described relief of symptomatic obstructive hydrocephalus due to cysticercus in the 4th ventricle where an endoscopic approach via a frontal burr hole was performed [19]. Recently, neuroendoscopic procedures are in vogue for removal of cysticercus cysts [14, 20, 21].…”

Eleven cases of intraventricular neurocysticercosis were managed over a 10-year period. All patients presented with features of hydrocephalus. In 9 cases the cysts were blocking the cerebrospinal fluid (CSF) pathway resulting in hydrocephalus. The 4 cases of lateral ventricular cyst had communicating hydrocephalus, while 2 of these had asymmetrical ventriculomegaly. Two of 4 cases had more than one cyst. One of 4 children with lateral ventricular cyst had narrowing of the foramen of Monro causing asymmetrical hydrocephalus. Following cyst removal, CSF diversion was not required in 6 cases, while 5 required CSF diversion despite removal of their cysts in 4 of 5. One patient had a cyst at the aqueductal inlet and he was managed by shunt and albendazole therapy. Thus, we managed 6 of our cases with excision of the cysts obstructing the CSF pathway, and in 4 cases excision of cysts with ventriculoperitoneal shunt was adequate.
