Extractions: Tell a friend Schizencephaly: A developmental disorder of the brain characterized by abnormal slits, or clefts, in the cerebral hemispheres. Schizencephaly is a form of porencephaly. Individuals with clefts in both hemispheres, or bilateral clefts, are often developmentally delayed and have delayed speech and language skills and corticospinal dysfunction. Individuals with smaller, unilateral clefts (clefts in one hemisphere) may be weak on one side of the body and may have average or near-average intelligence. Patients with schizencephaly may also have varying degrees of microcephaly, mental retardation, hemiparesis (weakness or paralysis affecting one side of the body), or quadriparesis (weakness or paralysis affecting all four extremities), and may have reduced muscle tone (hypotonia). Most patients have seizures and some may have hydrocephalus. In schizencephaly, the neurons border the edge of the cleft implying a very early disruption in development. There is now a genetic origin for at least one type of schizencephaly. Other possible causes may include environmental exposures during pregnancy such as medication taken by the mother, exposure to toxins, or a vascular insult. Often there are associated heterotopias (isolated islands of neurons) which indicate a failure of migration of the neurons to their final position in the brain.

Extractions: When my daughter was a 8 months old we noticed that she was having some delays in her motor skills. We took her to the neurologist and her diagnosis was 1. cortical dysplasia involving the right per-sylvian region with broad gyri which are diminished in number associated with thickened cortex. There is deep enfolding of the cortex with a deep sulcus which nearly reaches the lateral ventricle. While this is reminiscent of closed lip schizencephaly, a thin band of white matter separates the enfolded gray matter from the ventricular body. 2. Absence of the septum pellucidum. 3. The optic chiasm and nerves appear to be within normal limits for size.

Extractions: Brain tumors may be supratentorial or infratentorial. Brain tumors may produce obstetrical complications due to severe macrocephaly, or may present in the neonatal period as hydrocephalus, focal neurological findings, or massive bleeding. Supratentorial tumors in neonates occur more often than infratentorial tumors. Magnetic resonance imaging is the study of choice for neonates with suspected brain or spinal cord tumor. Teratomas, astrocytomas, choroid plexus papilloma, and primitive neuroectodermal tumors are the most frequent brain tumors in neonates. Teratomas constitute about one-third of all neonatal tumors (Figure 257.1). A B C Figure 257.1. MRI of the brain demonstrating a large teratoma. The tumor involves the left optic nerve (A) and extends beyond the skull (B and C) . Calcification (B). Astrocytomas also occur frequently. Astrocytic tumors may occur in neonates with tuberous sclerosis. Choroid plexus papillomas are usually in the lateral ventricles and produce hydrocephalus.

Extractions: Seizures may be the presenting sign of neonatal brain tumor. Seizures occur in about 14% to 20% of newborns with brain tumors. Brain tumors in neonates are more often supratentorial than infratentorial. Teratomas are the most frequent supratentorial tumors in neonates. They are usually present at the time of birth. Magnetic resonance imaging is the method of choice to diagnose brain tumors. Treatment is surgical. Chemotherapy is sometimes used. Radiotherapy is seldom used because of its deleterious effects on future neurological development. More about... Schizencephaly Schizencephaly consists of a canal, surrounded by cerebral cortex, that allows communication between the subarachnoid space and the ventricles. Schizencephaly is diagnosed by CT or preferably by MRI. The MRI appearance of schizencephaly is very characteristic. It consists of a thin or wide canal that extends from the cerebral cortex to the ventricles. Schizencephaly is unilateral or bilateral. The walls of the clefts or lips exhibit abnormal cortex with frequent neuronal heterotropia. The lips may be adjacent or distant from each other. Schizencephaly occurs most often in the regions of the Rolandic and Sylvian fissures. Schizencephaly may be associated with optic nerve hypoplasia and absence of the septum pellucidum.

Schizencephaly is a rare congenital anomaly of the brain, characterized by formation of abnormal unilateral or bilateral clefts in the cerebral hemispheres. It often manifests with partial seizures, mental retardation and hemiparesis. Only two cases of schizencephaly associated with psychosis have been reported in the literature. A patient of schizencephaly, who had bipolar affective disorder is described. It has been compared with the earlier two reported cases of schizencephaly associated with pyschosis.

Cephalic is a term that means " head " or "head end of the body." Congenital means the disorder is present at, and usually before, birth Cephalic disorders are not necessarily caused by a single factor, but may be influenced by hereditary or genetic conditions, nutritional deficiencies, or by environmental exposures during pregnancy , such as medication taken by the mother, maternal infection, or exposure to radiation (such disorders are more common in areas of the former Soviet Union affected by nuclear waste disposal problems, such as the area around the Mayak plant in Chelyabinsk Russia .) Some cephalic disorders occur when the cranial sutures (the fibrous joints that connect the bones of the skull ) join prematurely. Most cephalic disorders are caused by a disturbance that occurs very early in the development of the

Extractions: Schizencephaly is an extremely rare developmental disorder characterized by abnormal slits, or clefts, in the brain's cerebral hemispheres. Schizencephaly is a form of porencephaly in which there is a cyst or cavity in the cerebral hemispheres. Individuals with clefts in both hemispheres (bilateral clefts) are commonly developmentally delayed and have delayed speech and language skills and corticospinal dysfunction. Individuals with smaller, unilateral clefts (clefts in only one hemisphere) are often paralyzed on one side of the body and may have normal intelligence. Patients with schizencephaly may also have varying degrees of microcephaly (abnormally small head), mental retardation, hemiparesis or quadriparesis (partial or complete paralysis), and reduced muscle tone (hypotonicity). Most patients have seizures. Some may have hydrocephalus.
