✓ Cysts occupying the third ventricle are rare lesions and may appear as an unusual cause of obstructive hydrocephalus. Various types of lesions occur in this location, and they generally have an arachnoidal, endodermal, or neuroepithelial origin. The authors present a case of acute hydrocephalus following minor trauma in a child due to cerebrospinal fluid outflow obstruction by a third ventricular cyst. Definitive diagnosis of this cystic lesion was possible only with contrast ventriculography and not routine computed tomography or magnetic resonance imaging. The investigation, treatment, and pathological findings are discussed.

Abstract OBJECTIVE AND IMPORTANCE Colloid cysts of the third ventricle are rare benign tumors of endodermal origin accounting for 1% of all intracranial tumors. Interestingly, a few familial cases have been reported previously. We present the first case of dizygotic twins with a symptomatic colloid cyst of the third ventricle. CLINICAL PRESENTATION A 10-year-old boy was admitted to a local hospital in 1993 because of severe progressive headache. Computed tomographic and magnetic resonance imaging scans revealed acute obstructive hydrocephalus attributable to a third ventricular colloid cyst, which was removed after emergent ventricular drainage. Fourteen years later, a nonidentical twin brother complained of continuous headache with nausea and vomiting. A magnetic resonance imaging scan showed obstructive hydrocephalus and a third ventricle colloid cyst, which was removed by use of the transcallosal approach. INTERVENTION Both twins underwent complete removal of the cyst by the interhemispheric transcallosal approach without postoperative complications. CONCLUSION On the basis of a literature review, 2 cases of colloid cysts of the third ventricle in monozygotic twins and a few familial cases have been reported. Our case is the first in dizygotic twin brothers. These findings suggest that the prevalence of colloid cyst may be higher in twins than in the general population. We believe that the presence of this lesion in a twin necessitates magnetic resonance imaging of the other twin, and a clinical follow-up would be recommended in all other first-degree relatives.

Choroid plexus cysts are frequent benign intraventricular lesions that infrequently cause symptoms, usually in the form of obstructive hydrocephalus. These instances are even less common in the adult population. When warranted, treatment seeks to reestablish cerebrospinal fluid flow and does not necessarily require resection of the cyst itself. Hence, endoscopic exploration of the ventricles with subsequent cyst ablation is the current treatment of choice for these lesions.Herein we present the case of a 25-year-old female patient with a 3-week history of intermittent headaches. Investigation with computerized tomography (CT) of the head detected supratentorial hydrocephalus, with enlargement of the lateral and third ventricles. Magnetic resonance imaging revealed a homogeneous cystic lesion in the third ventricle. A right-sided, pre-coronal burr hole was carried out, followed by endoscopic exploration of the ventricular system. A third-ventriclostomy was performed. With the aid of the 30-degrees endoscope, a cyst arising from the choroid plexus was visualized along the posterior portion of the third ventricle, obstructing the aqueduct opening. The cyst was cauterized until significant reduction of its dimensions was achieved and the aqueduct opening was liberated. Postoperative recovery was without incident and resolution of the hydrocephalus was confirmed by CT imaging. The patient reports complete improvement of her headaches and has been uneventfully followed since surgery.The video can be found here: http://youtu.be/XBtj_SqY07Q.

✓ 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.

✓ Two patients with a history of progressive unilateral neurological symptoms and signs, and evidence of obstructive hydrocephalus from a mass lesion adjacent to the third ventricle as demonstrated by pneumography, were each found to have an intracerebral hematoma secondary to remote hemorrhage from a small vascular malformation. One patient died shortly after surgical exploration and the other after ventriculography. The pathophysiology of hydrocephalus associated with a vascular malformation is discussed and the need for considering a benign cause for obstructive hydrocephalus from a mass deep in the brain substance is emphasized.

Abstract BACKGROUND: The aqueduct of Sylvius (AqSylv) is a structure of increasing importance in neuroendoscopic procedures. However, there is currently no clear and adequate description of the normal anatomy of the AqSylv. OBJECTIVE: To study in detail hitherto unavailable normal magnetic resonance imaging morphometry and anatomic variants of the AqSylv. METHODS: We retrospectively studied normal midsagittal T1-weighted 3-T magnetic resonance images in 100 patients. We measured widths of the AqSylv pars anterior, ampulla, and pars posterior; its narrowest point; and its length. We recorded angulation of the AqSylv relative to the third ventricle as multiple deviations of the long axis of the AqSylv from the Talairach bicommissural line. We statistically determined age- and sex-related changes in AqSylv morphometry using the Pearson correlation coefficient. We measured angulation of the AqSylv relative to the fourth ventricle and correlated this to the cervicomedullary angle (a surrogate for head position). RESULTS: Patients were 13 to 83 years of age (45% male, 55% female). Mean morphometrics were as follows: pars anterior width, 1.1 mm; ampulla width, 1.2 mm; pars posterior width, 1.4 mm; length, 14.1 mm; narrowest point, 0.9 mm; and angulation in relation to the third and fourth ventricles, 26° and 18°, respectively. Age correlated positively with width and negatively with length of the AqSylv. There was no correlation between AqSylv alignment relative to the foramen magnum and the cervicomedullary angle. CONCLUSION: Normative dimensions of the AqSylv in vivo are at variance with published cadaveric morphometrics. The AqSylv widens and shortens with cerebral involution. Awareness of these normal morphometrics is highly useful when stent placement is an option during aqueductoplasty. Reported data are valuable in guiding neuroendoscopic management of hydrocephalus and aqueductal stenosis.

Abstract OBJECTIVE Surgical resection of deep-seated midline brain tumors does not always resolve obstruction of cerebrospinal fluid pathways, and an additional operation—ventricular shunting—is required. To prevent postoperative obstructive hydrocephalus, we combine tumor removal and internal ventricular shunting in 1 stage. METHODS Between 2000 and 2006, 82 patients with deep-seated midline brain tumors (tumors of the third ventricle, pineal region, thalamus, upper brainstem, and superior half of the fourth ventricle) underwent 84 tumor resections with intraoperative internal ventricular shunting. Two types of intraoperative shunting were performed: direct third ventriculostomy with fenestration of the premammillary membrane of the third ventricle floor and Liliequist's membrane, 53 operations; and aqueductal stenting, 30 operations. In 1 patient, third ventriculostomy and aqueductal stenting were performed simultaneously. RESULTS As most of the tumors had an infiltrative growth pattern, gross total tumor removal was achieved in only 31% of patients in this series. There were no fatal outcomes related to the surgery. Follow-up data were collected in 73 patients (89%) and ranged from 2 to 68 months (median, 16 months). Additional shunting because of inadequate function of stoma or stent was performed in 13 patients at various times after surgery (median, 30 days). The Kaplan-Meier survival analysis demonstrated that at 12 and 24 months the intraoperative direct third ventriculostomy success rates were 67 and 61%, respectively; aqueductal stenting success rates were 93% at both 12 and 24 months. CONCLUSION Intraoperative direct third ventriculostomy and aqueductal stenting under direct visual control were found to be reliable methods of hydrocephalus management in patients with deep-seated midline brain tumors.

Introduction Pituitary tumors from lactotrope cells account for about 40% of all functioning pituitary cancers. Men tend to present with a larger, more invasive and rapid growth prolactinomas than women, possibly because hypogonadism features are less evident. Case report A 27-year-old, previously asymptomatic Saudi man presented with a 3-day history of emesis with severe left-sided frontal headache, left face and right upper limb numbness, with signs of obstructive hydrocephalus. Brain Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) revealed a giant pituitary mass occupying several regions (sellar, infra-sellar, and supra-sellar) measuring 6.5 × 5.7 × 5.9 cm, and invading the sphenoid sinus as well as the cavernous sinuses bilaterally, with intra-pituitary hemorrhage compressing the third ventricle causing obstructive hydrocephalus. Prolactin levels were> 200,000 mIU/L, consistent with invasive giant prolactinoma (IGP). He was treated with Cabergoline which eventually normalized the prolactin level and significantly reduced the size of IGP. Conclusion This is a rare case of obstructive hydrocephalus with super-imposed intra-pituitary hemorrhage secondary to IGP, highlighting the importance of a full hormonal assessment for proper diagnosis and management.

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.
