Connective Tissue Disorders
Ehlers-Danlos Syndrome (EDS) and Marfan Syndrome are connective tissue disorders that affect the strength and elasticity of tissues. These conditions can make the dura (the membrane containing cerebrospinal fluid) more fragile, increasing the likelihood of spontaneous CSF leaks. EDS, in particular, is associated with joint hypermobility and skin that bruises easily, which may lead to spinal instability and increased pressure on the dura.
Idiopathic Intracranial Hypertension (IIH)
IIH is a condition characterised by increased pressure inside the skull, which can lead to tears in the dura, resulting in a CSF leak. Any CSF leak requires treatment, but controlling the IIH is essential to prevent repeat leaks. Without managing the underlying pressure issue, leaks can recur, causing chronic symptoms.
Cervical Instability (CCI)
CCI involves excessive movement or instability at the junction where the skull meets the spine. This instability can put pressure on the spinal cord and dura, potentially leading to a CSF leak. Individuals with EDS are more likely to experience CCI, as the weakened connective tissues exacerbate the instability.
Jugular Vein Compression
Compression of the internal jugular veins, often due to cervical spine disorders (such as CCI) or surrounding structures, can increase intracranial pressure. This condition, sometimes referred to as jugular outlet syndrome, may lead to venous hypertension, which raises the risk of a CSF leak. The increased pressure forces CSF through weak points in the dura, potentially worsening or causing spontaneous leaks
Chiari Malformation
Chiari Malformation occurs when brain tissue extends into the spinal canal, often due to an abnormally small or misshaped skull. It is sometimes misdiagnosed if the other signs spontaneous intracranial hypotension (SIH) are not recognised on a brain MRI. Chiari can also increase pressure on the dura, resulting in CSF leaks.
Acromegaly
Acromegaly is caused by excessive growth hormone production, leading to the enlargement of bones and tissues. This condition can increase pressure on the skull base and cause a CSF leak, especially if associated with structural changes in the cranial or spinal regions.
Hypovolaemia
Low blood volume, known as hypovolaemia, can reduce the pressure within the CSF system, making the dura more susceptible to tears. This condition might contribute to the development of CSF leaks, particularly when combined with other underlying health issues.
Spinal Cysts (Tarlov Cysts)
Tarlov cysts are fluid-filled sacs that form along the spinal nerve roots, which can put pressure on the dura and cause a CSF leak. These cysts may be asymptomatic but can sometimes enlarge or rupture, leading to symptoms of a CSF leak.
