CT Cisternogram Scan in Ahmedabad

What is a CT cisternogram?

A CT cisternogram is an advanced imaging scan that is used to examine the flow of cerebrospinal fluid (CSF) in the brain and spinal cord. It is the standard imaging scan to diagnose and locate cerebrospinal fluid (CSF) leaks, specifically those in the skull base.

What is the purpose of a CT cisternogram?

Healthcare professionals use this CT scan for various reasons, such as:

• Examine CSF flow: A CT cisternogram involves injecting a contrast material into the cerebrospinal fluid area, which helps visualise CSF flow.
• Detect CSF leaks: This CT scan helps detect CSF leaks. If a CSF leak is present, the contrast material will leak from the subarachnoid space, which allows doctors to pinpoint the exact location on the CT scan.
• Diagnose conditions: This CT scan not only detects CSF leaks but also helps diagnose hydrocephalus (a buildup of cerebrospinal fluid, or CSF) and other conditions affecting CSF flow.
• Plan treatment strategies: The CT scan helps detect the exact location of a CSF leak, which allows doctors to determine the appropriate treatment plan or surgery.

How is a CT cisternogram performed?

Firstly, you will lie on an examination table that slides into the round-shaped CT scan machine. You might be given anaesthesia to numb the area where the needle will be inserted. After that, a small amount of contrast material will be inserted into the spinal fluid. Several pictures will be taken over a period of time. You will be required to lie still during the whole procedure.

What does an abnormal CT cisternogram indicate?

An abnormal CT cisternogram may indicate several conditions, such as CSF leaks, blockages, and other conditions affecting the cerebrospinal fluid circulation. The potential causes of an abnormal CT cisternogram may indicate:

• CSF leaks: A contrast material glowing outside the normal CSF path may indicate a leak of CSF. This might be a result of trauma, surgery, or another condition that damages the skull base or dura mater.
• CSF blockages: A CT cisternogram can help reveal blockages in the normal flow of CSF, which is a possible cause of fluid buildup.
• Hydrocephalus: This condition refers to the excessive buildup of fluid in the ventricles of the brain. A CT cisternogram can help diagnose and determine the severity of the condition.
• Arachnoid cyst: This condition refers to the fluid-filled sacs in the brain, spinal cord, and the arachnoid membrane. These are not tumours, they are filled with cerebrospinal fluid. There are two types of arachnoid cysts, however, the most common type is a congenital arachnoid cyst.

However, since a CT scan cannot definitively diagnose all conditions, your doctor may order further tests to confirm the diagnosis.
