Hydrocephalus can be defined broadly as a disturbance of formation, flow, or absorption of cerebrospinal fluid (CSF) that leads to an increase in volume occupied by this fluid in the CNS. Correlation with the maternal and paternal head circumference is useful. Increase in volume of cerebrospinal fluid, Mass lesions and increase in volume of blood. Experience suggests that these conditions ought to be identifiable on a clinical basis. Skull causes of Macrocephaly. Some cases can slowly progress during the fetal period. Causes Common Causes. Various procedures may be considered for drainage of CSF in order to reduce the fluid volume including placement of a extraventricular drain or a ventriculoperitoneal (VP) shunt 19).

Macrocephaly: Macrocephaly is an unusually large head. Macrocephaly is customarily diagnosed if head circumference is greater than two standard deviations (SDs) above the mean. In this review, we will use the term macrocephaly to include conditions of megalencephaly. The term The Human Brain in Figures and Tables. Cafe Au Lait Spots Dr Gyorgy Fekete Ii Department Of Those with benign or familial macrocephaly are considered to have megalencephaly, another form of macrocephaly that will not result in the development of neurological disorders in the patient. Cowden syndrome is a disorder characterized by multiple noncancerous, tumor-like growths called hamartomas and an increased risk of developing certain cancers.Almost everyone with Cowden syndrome develops hamartomas. They are also implicated as a cause of macrocephaly and mild to severe developmental delay, regardless of the presence or absence of hamartomas in childhood. Macrocephaly, the increased head circumference is linked to various events that can result in an increase of orbito-frontal head circumference for age, including anomalies of bone skull structures, subdural fluid collections, hydrocephalus, intracranial masses, and arteriovenous malformations 3). In some cases, a correct reading of the head measurement may be particularly unfeasible, as the child may be too much restless or the tape measure may be not placed properly and the patient’s hair may be too thick to give a correct result. In this article, MomJunction acquaints you with the reasons behind disproportionately large heads in infants and if there is a cure to the problem. However, a recent study showing a child with aspartoacylase gene mutation developed microcephaly. Post vaccination:following vaccination against swine flu virus.

Periodic monitoring of head size is sufficient in these cases along with regular monitoring for physical growth and neurologic development. Benign familial macrocephaly is a primary macrocephaly and autosomal dominant 10) and multifactorial inheritances 11) had been proposed. The overall prognosis will depend on the underlying cause and associated anomalies.

Although not all cases of macrocephaly are cause for alarm, it is often accompanied by various symptoms or medical signs: generalized developmental delay , seizures, corticospinal dysfunctions, among others (National Institute of Neurological Disorders and Stroke, 2015). Benign enlargement of the subarachnoid spaces in infancy (BESS or BESSI) also known as benign external hydrocephalus (BEH) is, as per the name, a benign enlargement of the subarachnoid spaces in infants. Other causes are described below. A proper measure of the head circumference should be performed by putting the tape measure along the most prominent diameter of the occiput and the mid forehead; then, the results of the measurement must be checked with the head circumference growth charts, according to the age, gender, and height parameters 6). Achondroplasia is caused by a gain-of-function mutation in fibroblast growth factor receptor 3 (FGFR3). A careful physical exam will be done. Macrocephaly is associated with many genetic disorders and is a frequent cause of referral to the clinical geneticist. Probands with psychomotor impairment had bigger heads, and more had a history of birth difficulty than did unimpaired probands.
