✓ Thirty-eight cases of colloid cyst of the third ventricle are reviewed. Headache was the most frequent complaint but a strong positional relationship, supposedly a pathognomonic feature of this tumor, was seldom seen. A combination of progressive dementia and gait disturbance without evidence of papilledema, resembling the clinical picture in “normal-pressure” hydrocephalus, was present in eight patients. Sudden deterioration and death occurred in four cases; two other deaths were precipitated by lumbar puncture and pneumoencephalography. Ventriculography was the most reliable diagnostic study. Both the demonstration of dilatation of the lateral ventricles and an upward convexity in the initial segment of the internal cerebral vein in five of the 10 angiograms performed were highly suggestive of tumor. Removal of the colloid cyst through a cortical incision in the non-dominant hemisphere was carried out in 21 cases; in six it was necessary to enlarge the foramen of Monro by dividing the ipsilateral anterior column of the fornix. There were three deaths in the early and two in the late postoperative period. The main complication associated with the transventricular approach was the development of seizures.

Abstract Objective: To further assess the safety and long-term efficacy of endoscopic resection of colloid cysts of the third ventricle. Methods: A retrospective review of a series of 35 consecutive patients (18 male, 17 female) with colloid cysts treated by endoscopic surgery was undertaken. Results: The mean patient age was 32.4 years (range, 11–54 yr). Headache was the most common presenting symptom (22 patients). The average tumor size was 18 mm (range, 3–50 mm). The endoscopic technique could not be completed in six patients, necessitating conversion to an open craniotomy and a transcortical approach to the colloid cyst. All patients had histologically confirmed colloid cysts of the third ventricle, and complete resection of the lesion was confirmed macroscopically and radiologically in all patients. There were no deaths. Two patients developed aseptic meningitis without any permanent sequelae. One patient developed unilateral hydrocephalus attributable to obstruction of the foramen of Monro, which was treated with endoscopic septum pellucidotomy. The median follow-up period was 88 months (range, 10–132 mo). There was one asymptomatic radiological recurrence. No seizures occurred after surgery. Conclusion: The results of this study support the role of endoscopic resection in the treatment of patients with colloid cysts as a safe and effective modality. In some cases, conversion to an open procedure may be required. Additional follow-up will be required to continue to address the duration of lesion-free survival.

✓ Colloid cysts of the third ventricle are described in middle-aged twin brothers. One of them presented with recurrent attacks of headache. In this patient the cyst had reached a size large enough to obstruct the cerebrospinal fluid pathway, resulting in hydrocephalus. The twin brother, although asymptomatic, was suspected of the anomaly and investigated because of the similarity of his ocular signs. The diagnosis was confirmed by computerized tomography in both the patient and his brother. The latter proved to have a smaller colloid cyst situated anteriorly in the third ventricle with no obstructive hydrocephalus. The patient was successfully operated on, while the brother is still under observation. Both brothers have had bilateral cataracts, retinal detachments, and left lateral rectus palsies. The familial occurrence of colloid cysts and their association with these ocular findings have apparently not been described before.

Colloid Cysts

Colloid cysts are histologically benign lesions whose primary goal of treatment should be complete resection to avoid recurrence and sudden death. Open surgery is traditionally considered the standard approach, but, recently, the endoscopic technique has been recognized as a viable and safe alternative to microsurgery. The endoscopic approach to colloid cysts of the third ventricle is usually performed through the foramen of Monro. However, this route does not provide adequate visualization of the cyst attachment on the tela choroidea. The combined endoscopic transforaminal-transchoroidal approach (ETTA), providing exposure of the entire cyst and a better visualization of the tela choroidea, could increase the chances of achieving a complete cyst resection. Between April 2005 and February 2011, 19 patients with symptomatic colloid cyst of the third ventricle underwent an endoscopic transfrontal-transforaminal approach. Five of these patients, harboring a cyst firmly adherent to the tela choroidea or attached to the middle/posterior roof of the third ventricle, required a combined ETTA. Postoperative MRI documented a gross-total resection in all 5 cases. There were no major complications and only 1 patient experienced a transient worsening of the memory deficit. To date, no cyst recurrence has been observed. An ETTA is a minimally invasive procedure that can allow for a safe and complete resection of third ventricle colloid cysts, even in cases in which the lesions are firmly attached to the tela choroidea or located in the middle/posterior roof of the third ventricle.

Colloid Cysts

Abstract Colloid cysts are rare lesions that account for up to 2% of all intracranial tumors. They are commonly found posterior to the foramen of Monro in the third ventricle and classified as benign lesions due to their slow-growing nature. Diagnosis of colloid cysts are often incidental finds on diagnostic imaging or at autopsy. The strategic location of these cysts primary causes gradual or acute hydrocephalus, as evidenced by flattened gyri and deepened sulci on MRI, nausea, vomiting, and papilledema. Enlargement of the cyst itself can cause a mass effect, which commonly presents with symptoms of ataxia, memory loss, and rapid neurologic deterioration. Microsurgery, endoscopic removal, and stereotactic aspiration are cited to be the most commonly employed treatments in the management of colloid cysts. However, there is no one procedure better than another; the benefits and limitations of several procedures are discussed. Treatment of choice is weighed by clinical judgment and surgical experience that vary between neurosurgeons. Although benign, colloid cysts rarely but can lead to sudden death. Therefore, it is important to consider colloid cysts and other intracranial tumors on the differential diagnosis when presented with acute hydrocephalus and papilledema. We report a case of sudden death in a 22-year-old black female due to obstructive hydrocephalus by a colloid cyst in the third ventricle.

Surrounding Parenchyma

Colloid cysts are the most common benign neoplasms of the anterior third ventricle, mostly located at the level of the foramen of Monro and can often manifest as sudden onset headache or loss of consciousness. These cysts often have a well-defined cyst wall, mucinous or watery intracystic fluid and have a fairly good plane with the surrounding parenchyma. Occasionally, intracystic haemorrhage can lead to xanthogranulomatous inflammatory changes within the cyst resulting in focal thickening of the cyst wall and adhesion to the surrounding structures. Here we describe a case of xanthogranulomatous colloid cyst which is a very rare variant of colloid cyst.

✓ Surgical approaches to lesions located in the anterior and middle portions of the third ventricle are challenging, even for experienced neurosurgeons. Various exposures involving the foramen of Monro, the choroidal fissure, the fornices, and the lamina terminalis have been advocated in numerous publications. The authors conducted a microsurgical anatomical study in 20 cadaveric brain specimens (40 hemispheres) to identify an exposure of the third ventricle that would avoid compromising vital structures. An investigation of the variations in the subependymal veins of the lateral ventricle in the region of the foramen of Monro was performed, as these structures are intimately associated with the surgical exposure of the third ventricle. In 16 (80%) of the brain specimens studied, 19 (47.5%) of the hemispheres displayed a posterior location of the anterior septal vein—internal cerebral vein (ASV—ICV) junction, 3 to 13 mm (average 6 mm) beyond the foramen of Monro within the velum interpositum, not adjacent to the posterior margin of the foramen of Monro (the classic description). Based on this finding, the authors advocate opening the choroidal fissure as far as the ASV—ICV junction to enlarge the foramen of Monro posteriorly. This technique achieves adequate access to the anterior and middle portions of the third ventricle without causing injury to vital neural or vascular structures. The high incidence of posteriorly located ASV—ICV junctions is a significant factor influencing the successful course of surgery. Precise planning of the surgical approach is possible, because the location of the junction is revealed on preoperative neuroradiological studies, in particular on magnetic resonance venography. It can therefore be determined in advance which foramen of Monro qualifies for posterior enlargement to gain the widest possible access to the third ventricle. This technique was applied in three patients with a third ventricular tumor, and knowledge of the venous variations in this region was an important resource in guiding the operative exposure.

✓ An enlarged sella turcica was discovered in a 40-year-old man who had bitemporal headaches. A pneumoencephalograph revealed a third ventricular cyst, dilated lateral ventricles, and an empty sella. The colloid cyst was lined by foregut epithelium, probably originating in the respiratory tract, and dense connective tissue. This case is the first instance of an empty sella associated with a colloid cyst of the third ventricle. It is proposed that enlargement of the mass in the third ventricle caused increased pulsation pressure of the cerebrospinal fluid, and that in the presence of an incompetent diaphragma sellae the subarachnoid space expanded into the sella. The origin of third ventricle cysts is reconsidered. It is concluded that suprasellar colloid cysts may arise from endoderm, ectoderm, neuroepithelium, or a combination of these epithelia.

✓ Sixteen patients treated between 1969 and 1989 for a colloid cyst of the foramen of Monro by stereotactically guided aspiration (not stereotactic extirpation) were evaluated to assess the long-term outcome of the procedure. Thirteen of these patients required reoperation due to an acute comatose state, failure to achieve permanent reduction of the cyst, or symptomatic hydrocephalus. Of these 13, six were treated twice and two were treated three times by stereotactic aspiration. Five patients underwent microsurgical extirpation and three had a shunt placed following a failed aspiration. Failure of the first procedure was detected within the first 2 months after treatment in eight patients and after more than 6 years in seven. Following stereotactic aspiration, three patients experienced a temporary memory deficit and confusion and one patient suffered a central pain syndrome. Eleven of the 26 procedures were followed by a recurrence 6 to 15 years after treatment; seven recurrent cysts were detected after more than 8 years. Of the patients with recurrences, three did not undergo repeat surgery but showed an increase in cyst size at the latest follow-up examination. It is suggested that radical removal by open or stereotactically guided microsurgery is the method of choice since stereotactic aspiration fails to offer a radical or permanent treatment for colloid cysts of the third ventricle.

Abnormal Cilia

✓ Three colloid cysts of the third ventricle were examined by both transmission (TEM) and scanning electron microscopy (SEM). There was morphological diversity of the cyst surface on SEM, with ciliated and non-ciliated cells present. In some areas, the non-ciliated cells were more numerous and extended above the surface. Individual non-ciliated cells show a wrinkled cell surface and bleb-like structures. The TEM findings correlated well with SEM, revealing two cell types. The non-ciliated cells appeared to have both exocrine and apocrine activity. In ciliated cells, abnormal cilia were related to abnormal centrioles; also present were highly abnormal microvilli. The appearance of the surface was similar to a normal ventricular surface. By allowing a greater assessment of cell types and their distribution, SEM has added one additional dimension in the evaluation of colloid cysts and their possible derivation.

Object. Patients harboring colloid cysts of the third ventricle can present with acute neurological deterioration, or the first indication of the lesion may appear when the patient suddenly dies. The risk of such an occurrence in a patient already identified as harboring a colloid cyst is unknown. The goal of this study was to estimate the risk of acute deterioration in patients with colloid cysts. Methods. A retrospective study was made of a cohort of patients with newly diagnosed colloid cysts who were recruited in The Netherlands between January 1, 1993, and December 31, 1997. Seventy-eight patients were identified, all of whom displayed symptoms. Twenty-five patients (32%) presented with symptoms of acute deterioration; four patients died suddenly and the cysts were discovered at autopsy. The overall mortality rate was 12%. Results of a multivariate logistic regression analysis demonstrated that no subgroup of patients presenting without acute deterioration could be identified on the basis of patient age, duration of symptoms, cyst size, or the presence of hydrocephalus. The national incidence of colloid cysts in The Netherlands is 1/106 person-years; the prevalence was estimated to be 1800 asymptomatic colloid cysts. Conclusions. Acute deterioration was a frequent presentation among a national cohort of Dutch patients harboring symptomatic colloid cysts. The risk of acute deterioration in a symptomatic patient with a colloid cyst in The Netherlands is estimated to be 34%. The estimated risk for an asymptomatic patient with an incidental colloid cyst is significantly lower. These results strongly advocate the selection of surgical treatment for patients with symptomatic colloid cysts.
