Third ventricle: size and appearance in normal fetuses through gestation.

AbstractA 21-year-old male patient was operated for third ventricle tumor (central neurocytoma) and showed improvement in the early postoperative period. After 2 weeks of surgery, the patient neurologic status deteriorated with acute decreased level of consciousness. Neuroimaging of the brain revealed entrapped left temporo-occipital horns with adhesion bands at the level of the atrium. Patient was operated with neuronavigation-guided endoscopic approach to the left atrium through the left posterior parietal region. Band adhesiolysis was performed with no complications. The patient showed fast improvement, and follow-up brain magnetic resonance imaging after 2 years showed the release of the ventricular entrapment with significant regression of the left ventricle size.

Using an ultrasound technique, the widths of the third ventricle in a group of normal subjects was compared with groups of chronic schizophrenics and acutely ill schizophrenics. While the chronic patients showed a significantly wider ventricle (p < 0.5) from the other two groups, only 14% of the chronic patients had a third ventricle greater than the accepted normal maximum of 8 mm. Neuropsychological tests confirmed organic brain impairment in both chronic and acutely ill patients but there was no significant difference between chronic patients with large ventricles and those with normal size ventricles. This suggests that third ventricle size is not part of the schizophrenic disease process and is not related to the dementia seen in the late stages of the illness.

Colloid cysts of the third ventricle presenting with acute obstructive hydrocephalus due to intracystic and intraventricular hemorrhage are extremely rare. The authors report a case of a 43-year-old man with a hemorrhagic colloid cyst that was treated using endoscopic surgery. A small colloid cyst of the third ventricle was initially diagnosed in the patient, and he was treated conservatively at that time. On admission to the authors' institution he presented with sudden headache onset without neurological deficits. Computed tomography and MRI demonstrated a round hemorrhagic mass lesion in the third ventricle with bilateral intraventricular hemorrhage. Endoscopic resection was performed using a flexible videoscope. Only partial removal of the cyst was performed because of a tough cyst wall with highly viscous, hemorrhagic cystic contents. Histological examination revealed a typical colloid cyst wall and hemorrhage mixed within a mucinous substance. Postoperative serial neuroimaging demonstrated a gradual reduction in the residual cyst size and normalization in the lateral ventricle size.

SynopsisA case–control study was undertaken of volumetric computerized tomographic scan measures in 216 consecutive admissions for functional psychosis and 67 healthy community controls. Odds ratio analysis demonstrated significant linear trends in the association between increasing lateral and third ventricle volumes, and both RDC schizophrenia (N= 121) and schizoaffective disorder (N= 41); cases were consistently associated with larger volumes than controls. There was an association between larger third, but not lateral, ventricle size in affective psychoses (N= 54). These associations were statistically independent of intracranial volume, sex, social class and ethnicity, factors which were significantly associated with ventricular measures in the controls. There was no evidence of a threshold corresponding to the notion of normalversusenlarged ventricles.Within the schizophrenia group, there were no large or significant associations between ventricle dimensions and age at onset, duration of illness or pre-morbid social functioning. Neither obstetric complications nor a family history of schizophrenia or other psychiatric illness was associated with large ventricles in these cases.

Abstract Background and aim: Assessment of normal dimension of cerebral ventricles is important for early detection of changes due to intrinsic and extrinsic pathology producing ventriculomegaly. Hence normal upper and lower limits of the cerebral ventricular system in various age groups and in both sexes are important for diagnosing it. Our aim is to establish a baseline reference value for the third and fourth ventricular width using Computed Tomogram [CT] for normal South Indian population. Materials and methods: 100 subjects aged between 5 to 90 years, comprising of 54 males and 46 females, with normal CT brain were analyzed. Subjects with intracranial and intraventricular pathology were excluded. Axial CT brain was obtained in Siemens Somatom scope multislice slice CT scanner. The widest diameter of the third and fourth ventricles on axial images using linear approach was measured. Student’s t test and one way analysis of variance was used. Results: Mean third ventricle size in male: 5.11 +/- 2.37 mm and in female: 4.35 +/- 2.08 mm. Mean fourth ventricle size in male: 13.40 +/- 1.66 mm and in female: 12.84 +/- 1.85 mm. Conclusion: The highest of the dimension in the third ventricle occurs in the highest age group of ≥60 years in both males and females. There was a steady rise in the third ventricle size across age groups until the seventh decade.
