“…Recently, 2 case reports on the radiosurgical management of colloid cysts of the third ventricles have been published. The strategy was initial management of the presenting hydrocephalus by either a shunt procedure or stereotactic cyst aspiration followed by stereotactic radiosurgery for the cyst wall [8, 9]. The rationale for the use of radiosurgery for the treatment of the cyst wall in colloid cysts is the cessation of mucous production by goblet cells as well as the devascularization of epithelial cells in the wall of the cyst [8].…”

“…Stereotactic radiosurgery presents an attractive treatment alternative to surgical resection because of its low presumed morbidity. There have been two case reports on stereotactic radiosurgery for third ventricle colloid cysts [8,9]. Here we present the first clinical case series on the treatment of third ventricle colloid cysts with gamma knife (GK) radiosurgery to determine its efficacy and safety.…”

Introduction: Colloid cysts often occur in the third ventricle, and they are considered benign, slowly growing lesions. They commonly present with symptoms of intracranial hypertension and rarely sudden death due to acute hydrocephalus. The management options include cerebrospinal fluid diversion procedure by shunt, endoscopic or transcranial surgical excision, and stereotactic aspiration. Complications associated with excisional procedures make them undesirable to some patients. Stereotactic radiosurgery has emerged as a noninvasive less risky treatment option. To date, there is no clinical series in the literature reporting on this treatment modality. The aim of the study was to determine the efficacy and safety of gamma knife (GK) radiosurgery in the treatment of third ventricular colloid cysts. Methods: This is a retrospective study involving 13 patients with third ventricular colloid cysts who underwent GK radiosurgery. GK radiosurgery was used as a primary treatment in all the patients. The median prescription dose was 12 Gy (11–12 Gy). The cyst volumes ranged from 0.2 to 10 cc (median 1.6 cc). Results: The median follow-up was 50 months (18–108 months). Cyst control was achieved in 100% of the patients. Complete or partial response was observed in 12 patients (92%). Eight patients (62%) had hydrocephalus on imaging at the initial diagnosis. Seven of these patients had VP shunt insertion before GK. One patient required shunt insertion after GK. Conclusion: GK for third ventricular colloid cysts is a promising treatment, regarding its efficacy and safety, to be added to other treatment options. A longer follow-up is required to confirm long-term control.

“…Although there are some papers describing other surgical approaches, as stereotactic aspiration, the most popular ones are neuroendoscopic and microsurgical approaches [14][15][16][17]. The neuroendoscopic approach is considered a first-line treatment in cases of ventricular dilatation because it is safe and effective, although there is a higher risk of partial resection, but it varies with neurosurgeon experience.…”

Colloid cysts (CCs) are rare brain tumors that cause nonspecific neurological signs associated with acute or chronic increased intracranial pressure. They are usually located in the third ventricle and rarely in the lateral ventricle. This is a report of an unusual case of CC located in the lateral ventricle. A 36-year-old male patient presented a story of progressive holocranial headache that would get worse with head mobilization and cough. Radiological analysis demonstrated enlargement of the right lateral ventricle due to a cyst blocking the right foramen of Monro. The patient underwent endoscopic neurosurgery and the cyst was totally resected. Histological evaluation diagnosed a CC. Postoperative images showed no cyst remaining and normalized ventricular size. The patient evolved with total improvement of the symptoms. Literature review shows that it is a very uncommon entity. Lateral ventricle CCs as a cause for unilateral hydrocephalus is a very rare entity. Neuroendoscopic approach is a firstline treatment option for this condition.

“…This modality of treatment is certainly attractive considering the duration of the procedures, short hospital stay, rapid recovery, and return to work, as opposed to the multitude of possible complications reported with surgical resection, including loss of short-term memory secondary to fornix injury. [ 5 ] The authors have more recently treated two other patients utilizing the same technique, but these were not included in the present report as follow-up is less than 2 years.…”

“…More recently, a case report of a symptomatic colloid cyst treated by a ventricular peritoneal shunt followed by Gamma knife stereotactic radiosurgery showed no further growth of the cyst at the 43-month follow-up magnetic resonance imaging (MRI). [ 5 ]…”

Background:Colloid cysts are rare benign lesions with potentially devastating results. Complications intra and posttreatment can result in high rates of recurrence. Stereotactic radiosurgery may present an attractive option for decreasing the rate of recurrence in conjunction with stereotactic aspiration.Case Description:Here, we report four cases of colloid cyst of the third ventricle managed by stereotactic aspiration with the use of the Leksell frame followed by stereotactic radiosurgery with the BrainLab/Novalis linear accelerator. Follow-up ranged from 7 to 10 years. There were no complications related to the treatment and no recurrence of the cysts, to date. All four patients remain asymptomatic.Conclusions:The combination of stereotactic aspiration and radiosurgery may have a role in the management of colloid cysts of the third ventricle.
