INDICATIONS :

• CSF leaks :  To diagnose and localize cerebrospinal fluid leaks.

• Hydrocephalus : To evaluate the patency of the CSF pathways and diagnose hydrocephalus.

• Cranial nerve disorders :   To evaluate the relationship between cranial nerves and surrounding CSF spaces.

• Brain tumors :  To evaluate the extent of brain tumors and their relationship with surrounding CSF spaces.

• Infections : To diagnose and evaluate the extent of infections, such as meningitis or abscesses.

CONTRAINDICATIONS:

• Allergy to contrast :  Patients with a known allergy to iodine-based contrast agents may not be suitable for CT Cisternograms.

• Kidney disease:  Patients with severe kidney disease may not be suitable for CT Cisternograms due to the risk of contrast-induced nephropathy.

• Pregnancy :  CT Cisternograms  are generally avoided during pregnancy due to radiation exposure.

PREPARATION :

• Fasting : Patients may be required to fast for several hours before the test.

• Removal of metal objects :  Patients will be asked to remove any metal objects, such as jewelry or clothing with metal fasteners.

• Lumbar puncture :  A lumbar puncture (spinal tap) may be performed to inject contrast agent into the CSF spaces.

PROCEDURE :                                                                                                                                                                                                      1. CT scanning :   The patient will lie on a table that slides into a large, doughnut-shaped machine. The CT scanner will rotate around the patient, taking X-ray images from different angles.

2.Contrast agent administration  :  The contrast agent will be administered through the lumbar puncture, and the patient will be asked to remain still for a few minutes.

3. Imaging:  The CT scanner will take images of the brain and CSF spaces.

RISK AND COMPLICATIONS:

1.Radiation exposure :  CT Cisternograms involve radiation exposure, which may increase the risk of cancer.

2. Contrast agent reactions  :  Some patients may experience allergic reactions or kidney damage from Athe contrast agent.

3. Lumbar puncture complications : Lumbar puncture may cause headache, nausea, or vomiting.

•Normal results :   A normal CT Cisternogram will show normal CSF spaces and no evidence of leaks or blockages.

•Abnormal results :  Abnormal results may indicate CSF leaks, hydrocephalus, or other conditions affecting the CSF spaces.

DIAGNOSTIC BENEFITS :

1. Accurate diagnosis :  Cisternograms provide detailed images of the cerebrospinal fluid (CSF) spaces, helping doctors diagnose conditions such as CSF leaks, hydrocephalus, and brain tumors.

2. Localization of CSF leaks : Cisternograms can help identify the exact location of CSF leaks, which is essential for planning treatment.

3. Evaluation of CSF dynamics :  Cisternograms can assess CSF flow and pressure, helping doctors diagnose conditions such as hydrocephalus.

TREATMENT BENEFITS :

1. Surgical planning :  Cisternograms provide detailed information about the anatomy of the CSF spaces, helping surgeons plan and execute surgical interventions.

2. Monitoring treatment response :  Cisternograms can be used to monitor the response to treatment, such as shunting for hydrocephalus.

3. Reducing complications :  Cisternograms can help reduce complications during surgery by providing detailed information about the anatomy of the CSF spaces.

PATIENT BENEFITS :

1. Minimally invasive :  Cisternograms are minimally invasive, reducing the risk of complications and promoting faster recovery.

2. Quick procedure :  Cisternograms are relatively quick, taking about 30-60 minutes to complete.

3. Detailed images :  Cisternograms provide detailed images of the CSF spaces, helping doctors diagnose and treat conditions more effectively.
