Because the aqueduct is so narrow, it can be obstructed by debris arising in the ventricular system (for example, sloughed cells or purulent material from an infection or blood products stemming from a hemorrhage). An additional feature is obliteration of the subarachnoid space over the cerebral convexities so that the brain appears closely pushed against the inner table of the calvarium. Fatigue, especially during times of increased activity. Aqueductal stenosis was previously classified as malformative or acquired (34). Idiopathic aqueductal stenosis (AS) may account for up to 59% of cases presenting with triventricular noncommunicating hydrocephalus.1 The clinical presentations associated with triventricular hydrocephalus differ depending on age at onset and the acuity of obstruction. Though isolated aqueductal stenosis is the most frequent form, a large percentage of patients manifest additional anomalies (32). Premature delivery or cystic parenchymal change occurred in those who experienced rapid development; except for the stable cases, all required surgical intervention. Neuroendoscopic surgical techniques are now employed with increasing frequency in cases of intraventricular infection to lyse and remove purulent material or other debris and irrigate the ventricular cavities with antibiotic saline; secondary hydrocephalus in such cases may require additional shunting (18). Nearly 3,000 illustrations, including video clips of neurologic disorders. Barkovich AJ, Raybaud C. Pediatric neuroimaging. The recurrence risk for isolated aqueductal stenosis is estimated at 4% (48). Without history or corroborating imaging, the cause of congenital stenosis is sometimes unknown, although a perturbation in embryonic development may be postulated in some cases. This is an uncertain entity in a mother and two of her sons reported by Verhagen et al., (1998). . 7. This article is confined to the discussion of isolated aqueductal stenosis and secondary changes. In some cases, this is due to a brain tumor compression (such as a pineal tumor) surrounding the aqueduct of Sylvius. Diagnosis. Retrospective review of our database searching for the keywords of aqueductal stenosis from August 2009-April 2015, yielded 15 cases of adult onset aqueductal stenosis confirmed on a midsagittal FIESTA or CISS image. The most frequent cause of hydrocephalus in the perinatal period is isolated aqueductal stenosis. By older estimates, isolated aqueductal stenosis occurs in two in every 1000 births (32).

Detailed anatomic and genetic workup is necessary to confirm or rule out syndromes or specific etiologies (for example, L1CAM mutation or X-linked hydrocephalus). The first report of aqueductal stenosis in NF-1 was made by Pennybacker in 1940. Narrowing of the cerebral aqueduct of Sylvius is termed aqueductal stenosis. Posthemorrhagic hydrocephalus may be due to intra-aqueductal blockage by blood descending from the lateral and third ventricles in intraventricular hemorrhage in the perinatal period. Associated birth defects include neural tube defects and those that result in aqueductal stenosis. Emery SP, Greene S, Hogge WA.

The consequences and treatment of this condition are discussed in the following paragraphs. Compression of the aqueduct also may result from a persistent and enlarging suprapineal recess of the third ventricle, which usually is a transitory fetal structure or adjacent scarring or gliosis (38). Other sign and symptoms of the condition include severe intellectual disability and spasticity. [A rare cause of amenorrhea: stenosis of the aqueduct of Sylvius.

An official website of the United States government. However, endoscopic aqueductoplasty has a high risk of long-term failure and is not recommended by some authors who recommend endoscopic third ventriculoscopy as a preferred surgical approach (Marx et el 2019). Twopatients developed obesity, one rapidly, the other in association with an abnormaldis-tribution ofbody hair in late adolescence. Acquired stenosis, even with late onset, may be due to compression from a mass. The 2023 edition of ICD-10-CM G91.1 became effective on October 1, 2022. Prenat Diagn 2020;40(1):58-65. The authors examined the visual function in 19 cases of non-tumoral aqueduct stenosis. HHS Vulnerability Disclosure, Help FOIA BACKGROUND: Although late-onset idiopathic aqueductal stenosis (LIAS) is considered a good indication for endoscopic third ventriculostomy (ETV), the characteristics of this clinical entity have seldom been reported in the magnetic resonance (MR) imaging era. [A rare case of aqueductal stenosis due to venous angioma]. The AS patients had better postural functions, walked faster, performed better cognitively and had a higher wakefulness than INPH patients, but these differences were explained by age differences between groups. Anatomy-Based Diagnoses. AJNR Am J Neuroradiol 2018;39(5):942-8. Long-term reliability of neuroendoscopic aqueductoplasty in idiopathic aqueductal stenosis-related hydrocephalus. Localized swelling in the periventricular and particular periaqueductal tissue also contributes to narrowing and eventual obstruction of the lumen of the aqueduct (05).

Some cases also include bilateral congenital agenesis of the foramen of Monro for CSF flow from the lateral ventricles into the third ventricle (23). Heterogeneity and recurrence risk for congenital hydrocephalus (ventriculomegaly): a prospective study. The site is secure. A series of 55 cases is described in which hydrocephalus associated with non-neoplastic narrowing of the Sylvian aqueduct produced symptoms for the first time in adult life. HHS Vulnerability Disclosure, Help High quality registry-based data worldwide may clarify the reasons for the higher incidence of hydrocephalus and aqueductal stenosis in lower income parts of the world (45). Rhombencephalosynapsis is associated with aqueductal stenosis in some cases of alobar holoprosencephaly, but most often rhombencephalosynapsis occurs in septo-optic-pituitary dysplasia without aqueductal stenosis (see the Medlink topic Rhombencephalosynapsis). The chief diagnostic criterion for ventriculomegaly is an atrial diameter greater than 10 mm measured ultrasonographically. .

This indicates that there is increased fluid in the ECS of the brain of the aqueductal stenosis cases, supporting the hypothesis that the parallel pathway for CSF egress is via the ECS. Neuropathological hallmarks of fetal hydrocephalus linked to CCDC88C pathogenic variants. Additional findings may implicate aqueductal stenosis as the cause of enlarging ventricles, chiefly funnel-shaped aqueduct and even direct visualization of an obstructing web or blood clot in the aqueduct (19). Childs Nerv Syst 2020;36(7):1407-14. In the stenosis type, the lumen of the channel is lined by ependymal cells, and there is no gliosis.This type is probably due to developmental errors and may largely vary from simple stenosis to atresia.
