“…The diagnostic and treatment dilemma is to differentiate between a "true" symptomatic TFV and other conditions associated with a large fourth ventricle. This dilemma is especially significant when attempting to identify those patients who may potentially benefit from surgery, as opposed to those patients with a well-compensated process wherein ventricular dilation terminates spontaneously with normal intracranial pressure, at which point it may be termed "compensated" or "arrested" hydrocephalus [3][4][5][6]. Schick and Matson reported that this spontaneous termination occurs in 10-15% of cases of supratentorial hydrocephalus [7].…”

“…There are similar studies in CT scan images as well by Murshed et al [ 11 ], Uysal et al [ 12 ], and Uthman et al [ 13 ]. The foramen being a transition zone between the cerebrum and the spinal cord has innumerable clinical implications as reported in several pieces of literature such as “Unusual Subacute Diencephalic Edema Associated with a Trapped Fourth Ventricle: Resolution following Foramen Magnum Decompression” by Udayakumaran et al [ 14 ] and “Acute Foramen Magnum Syndrome Caused by an Acquired Chiari Malformation after Lumbar Drainage of Cerebrospinal Fluid: Report of Three Cases” by Dagnew et al [ 15 ]. We hope that this study augments the existing literature and provides valuable information for future studies focusing on this region and also contributes to forensic analysis.…”

Purpose. The structural integrity of foramen magnum is usually preserved in fire accidents and explosions due to its resistant nature and secluded anatomical position and this study attempts to determine its sexing potential. Methods. The sagittal and transverse diameters and area of foramen magnum of seventy-two skulls (41 male and 31 female) from south Indian population were measured. The analysis was done using Student's t-test, linear correlation, histogram, Q-Q plot, and Binary Logistic Regression (BLR) to obtain a model for sex determination. The predicted probabilities of BLR were analysed using Receiver Operating Characteristic (ROC) curve. Result. BLR analysis and ROC curve revealed that the predictability of the dimensions in sexing the crania was 69.6% for sagittal diameter, 66.4% for transverse diameter, and 70.3% for area of foramen. Conclusion. The sexual dimorphism of foramen magnum dimensions is established. However, due to considerable overlapping of male and female values, it is unwise to singularly rely on the foramen measurements. However, considering the high sex predictability percentage of its dimensions in the present study and the studies preceding it, the foramen measurements can be used to supplement other sexing evidence available so as to precisely ascertain the sex of the skeleton.

“…Endoscopic approaches include endoscopic fenestration, aqueductoplasty, aqueductal stenting, and cysto-ventricular fenestration with or without shunting (21,22) . Some authors favored a direct microsurgical opening of the outlet of the fourth ventricle, avoiding the insertion of a fixed foreign body, as the preferred primary surgical option for entrapment of the fourth ventricle (23) . Other authors claimed shunting the fourth ventricle was the less invasive and more effective approach.…”

Background: Trapped fourth ventricle (TFV) is a rare clinico-pathological syndrome, usually resulting from inflammatory conditions (post-infective and post-hemorrhagic) that may present with serious brain stem compression manifestations. Many treatment modalities have been described with varying degrees of success. Objectives: To evaluate our results in managing the trapped 4 th ventricle by inserting 4 th ventricular catheter and connecting it to the previously implanted ventriculoperitoneal (VP) shunt via Y connector. Patients and Methods: A total number of 12 cases with TFV were diagnosed and treated surgically between 2014 and 2021 by a fourth ventricular catheter and connection to the pre-existing shunt via a Y-connector. Preoperative clinical and radiological findings were reported. Postoperative improvement was evaluated during a mean follow-up of 4.3 years. Postoperative complications were reported Results: 12 patients (6 males and 6 females), with a mean age of 3.3 years diagnosed with trapped fourth ventricles were included. All patients had previous VP shunts. Headache, vomiting, abnormal movement, gait disturbance, and nystagmus were the common symptoms. Trapped fourth ventricle was post-infectious in 6 (50%) patients, posthemorrhagic in 4 (33.3%) patients, and congenital in 2 (16.7%) patients. 6 (50%) patients had preoperative slit lateral ventricles and 4 (33.3%) had multiloculated hydrocephalus. Postoperatively 10 (83.3%) patients had clinical improvement while 2 (16.7%) remained as preoperative. All patients had a decrease in the 4 th ventricular size. Complications of surgery were minor. Conclusion: Fourth ventricular shunting with a Y connector is a valuable and effective modality of treatment in TFV, especially when other methods fail or in specific complex pathological situations, with fewer complications.

Unusual subacute diencephalic edema associated with a trapped fourth ventricle: resolution following foramen magnum decompression

Abstract: In this paper, we review the pre-morbid history, clinical syndrome, and imaging. We then discuss possible mechanisms, their implications on decision-making, and the preferred modes of treatment.
