Cavum septum pellucidum (CSP) is a normal variant CSF space between the leaflets of the septum pellucidum Cavum septum pellucidum is always visualized between 18 and 37 weeks and within a biparietal diameter of 44 to 88 mm. Failure to detect the cavum septum pellucidum within this time interval requires further investigation The normal septum pellucidum is a thin vertical partition composed of two thin laminae in apposition with each other in the median plane and separated by a narrow median cleft of variable size which is known as the cavum septi pellucidi. The septum pellucidum is triangular in shape and intervenes between the two lateral ventricles
The septum pellucidum, which separates the lateral ventricles, appears in the mid-sagittal section of a normal brain as a triangular structure, with the base of the triangle directed toward the inferior aspect of the corpus callosum 17 x 14 mm focus in the septum pellucidum demonstrates isointense T1 signal, hypointense T2 signal with signal loss on susceptibility weighted imaging (SWI) in keeping with hemorrhage. Subtle T2 and SWI hypointensities in the occipital horns of the lateral ventricles, in keeping with intraventricular extension of hemorrhage The septa of the cavum septum pellucidum and vergae begin to fuse from posterior to anterior from approximately 24 weeks gestation. By term, the cavum vergae is closed in 97% of babies, whereas the cavum septum pellucidum persists in most at this stage 4 Anomalies of the corpus callosum (ACC) and septum pellucidum are disorders of prosencephalic midline development, which are often associated with other brain abnormalities or may be part of a syndrome. Diagnosis of ACC is usually impossible before 18 to 20 weeks' gestation because the formation of the corpus callosum is incomplete The septum pellucidum is a structure that is marginated by the corpus callosum and body of the fornix. It is composed of white matter leaves along the medial walls of the lateral ventricles and is lined by ependyma along its ventricular surfaces [ 11] (Fig. 1)
Intraventricular neoplasms are rare and arise from periventricular structures such as the walls of the ventricular system, the septum pellucidum and the choroid plexus. Many tumor types arise from or can bulge into the ventricular system, although there are certain lesions that are relatively restricted to ventricles Cavum vergae cysts are rare lesions which are usually asymptomatic.It should not be confused with cavum septum pellucidum et vergae which is common. Although there is no actual pathological distinction between a run-of-the-mill cavum vergae and a cavum vergae cyst, the latter is sometimes used to denote a transverse diameter of more than 1 cm 4 or when the outer margins are convex It is a fluid-filled cavity within the leaflets of septum pellucidum, which follows the cerebrospinal fluid (CSF) signal intensity on all sequences located anterior to columns of fornix.

. This communication presents computerized tomography (CT) and magnetic resonance imaging (MRI) findings in six patients with septum pellucidum cysts, ages ranging from 1.5 to 47 yrs The septum pellucidum is a small membrane wall in the brain of humans and some animals. Its main job is to separate the lateral ventricles, important passageways within the brain tissue, and the membrane forms what's basically a barrier between these sections
The absence of the septum pellucidum is a rare condition that affects the structure of the brain. Specifically, a thin membrane called the septum pellucidum is missing from its normal position in the middle of the brain. When it is missing, symptoms may include learning difficulties, behavioral changes, seizures, and changes in vision.Absence of the septum pellucidum is not typically seen as.

Cavum septum pellucidum Cysts of the cavum septi pellucidi (CSP), cavum vergae (CV) and cavum velum interpositum (CVI) are anterior midline intracranial findings which are typically incidental. They are persistent, primitive, or acquired, midline structures, fluid-filled, generally communicating located between the third ventricle and corpus callosum. It is sometimes called the fifth ventricle. Septum pellucidum variants are of no clinical significance, and no further diagnostic workup is required (Born et al. 2004). 220.127.116.11 Lipoma Lipomas are very rare in the brain Fenestration of the septum pellucidum is one of the findings in chronic obstructive hydrocephalus.

Screening the cavum septi pellucidi (CSP), more commonly referred to as the cavum septum pellucidum, is a required component of the fetal anatomic survey during second-trimester ultrasound (US) BACKGROUND AND PURPOSE: The cavum septum pellucidum, a cavity filled with CSF, is localized between the 2 lateral ventricles of the brain. The cavum is present in all neonates, but it typically closes within 5 months after birth. In some cases, this closure does not occur and a persistent or enlarged cavum septum pellucidum has been linked, in some studies, to psychiatric disorders Absence of the septum pellucidum was never seen as an isolated finding. By using data gathered from the review of the MR scans of patients in this study, we devised a diagnostic algorithm to aid in the classification of these patients. Absence of the septum pellucidum can provide a valuable clue to the diagnosis of malformations of the brain 1. Introduction. The cave of septum pellucidum (CSP) is an important landmark in the evaluation of the fetal neural axis. It appears as a rectangular or triangular cavity, that contains cerebrospinal fluid (CSF) that filters from the ventricles through the two leaflets of the septum pellucidum [, , ].Visualization of a normal CSP in the second and third trimester prenatal ultrasound.
The first report of congenital absence of the septum pellucidum was made by Tenchini (1) in 1880, in a boy of two and a half years who was normal mentally. Hochstetter (2) added three cases.

Extreme forms of hydrocephalus, especially those that arise antenatally, may be mistaken for HPE, as the septum pellucidum may be ruptured and the sulcation poorly developed. Yet the hemispheres are clearly separated, and children with hydrocephalus are macrocephalic, whereas children with HPE are either micro- or normocephalic
Although this septum pellucidum tract (SPT) has been observed previously, its connections were unclear due to ambiguity and limited resolution of conventional MRI images. It is now possible to identify detailed parts of SPT with the increased resolution of TDI, which involves diffusion MRI imaging, whole-brain tractography, and voxel.

A rare complication of a ventriculoperitoneal (VP) shunt is reported. Serial imaging studies demonstrated the formation of an expanding septum pellucidum cyst after an indwelling shunt tube penetrated the wall of the septum pellucidum. This complication should be borne in mind if patients have symptoms of intermittent obstructive hydrocephalus or related to pressure effects from the septum. The American Institute of Ultrasound in Medicine and American College of Radiology recommends septum pellucidum as one of regular check-up required in the antepartum sonography. It is suggested that the septum pellucidum examination in antenatal care in Indonesia is conducted so that an early treatment plans can be made.
