What is the outcome for a fetus with ventriculomegaly? Ventriculomegaly seems to occur more often in male fetuses than in female fetuses. Sometimes the ultrasound will only show one of the ventricles even though there are two (one on the right, and one on the left side). If the lateral ventricles are 10 millimeters or greater in size then you will be told that your fetus has "ventriculomegaly". With the ultrasound the doctor will look at your fetus’s brain and measure the ventricles. When you are pregnant you will have an ultrasound. Ventriculomegaly is when the fluid filled structures (lateral ventricles) in the brain are too large. CSF cushions the brain and spinal cord from jolts. Cerebrospinal fluid is a clear, watery liquid that surrounds the brain and spinal cord, and is also found throughout the ventricles (brain cavities and tunnels). The entire surface of the brain and spine cord is bathed by a clear, colorless fluid called cerebrospinal fluid (CSF). The test can be ordered as an urgent request.The two components of the central nervous system are the brain and the spinal cord. The expected in-lab turnaround time should be less than one hour. The assays are run throughout the day and night in the Gloucester laboratory. The date and time of the current lumbar puncture.The time and date of the onset of current symptoms/event.Date of any previous lumbar puncture (if within the last month).Sample tube: 2mLfluoride-oxalate tube (grey top).Sample tube: Plain Universal container (tubes containing gel or anticoagulant are not suitable for analysis of CSF protein).Samples from CGH are sent directly to GRH Pathology from the ward or from CGH Pathology if delivered there.Results on bloodstained samples will be unreliable.1mL of CSF is approximately equal to 25 drops from the Luer connector of the needle.If other investigations required please check CSF Sample Requirements for further details. Glucose levels are usually normal in viral infections of the CNS.Whilst not diagnostic, low glucose levels, as compared to plasma levels, are seen in bacterial meningitis, cryptococcal meningitis, malignant involvement of the meninges and sarcoidosis.There may be a 2–4 hour lag in the CSF level when compared to the blood level. Glucose levels in CSF normally reflect the levels seen in the blood.
