Description: A space enclosed within the laminae of the septum pelludicum, the membranous partition that seperates the frontal horns of the ventricle. contains cerebrospinal fluid (CSF) that filters from the ventricles through the septal laminae. bounded anteriorly by the genu of the corpus callosum; superiorly by the body of the corpus callosum; posteriorly by the anterior limb and pillars of the fornix; inferiorly by the anterior commissure and the rostrum of the corpus callosum; and laterally by the leaflets of the septum pellucidum.

Description: One of two layers of both white and gray matter of the septum pellucidum. During fetal development there is a space between the two laminae called the cavum septum pellucidum which, in ninety per cent of cases, disappears during infancy.

Description: 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 an isolated finding. Instead, absence of the septum pellucidum is associated with other conditions such as septo-optic dysplasia . Treatment options for the condition vary depending on the underlying disorder. Diagnosis of absence of the septum pellucidum can be made through imaging such as an MRI. Symptoms of absence of the septum pellucidum typically present during childhood, but a diagnosis can also be made before an individual is born (prenatally). If an individual is found to be missing the septum pellucidum, a search for an underlying disorder should be made.

Description: A triangular double membrane, consisting of glial cells and fibers (Heimer, 1996) separating the anterior horns of the lateral ventricles of the brain. It is situated in the median plane and bounded by the corpus callosum and the body and columns of the fornix.

Description: A benign brain tumor composed of neural elements which most often arise from the SEPTUM PELLUCIDUM and the walls of the lateral ventricles. Immunohistochemistry and electron microscopy evaluations may reveal expression of neuron specific enolase and synaptophysin and cells containing microtubuli, neurosecretory granules, and presynaptic vesicles (MeSH).

Description: Porencephaly-cerebellar hypoplasia-internal malformations syndrome is rare central nervous system malformation syndrome characterized by bilateral porencephaly, absence of the septum pellucidum and cerebellar hypoplasia with absent vermis. Additionally, dysmorphic facial features (hypertelorism, epicanthic folds, high arched palate, prominent metopic suture), macrocephaly, corneal clouding, situs inversus, tetralogy of Fallot, atrial septal defects and/or seizures have been observed.
