Cerebrospinal fluid leaks are diagnosed by performing different tests. A diagnostic dural puncture is commonly used because its results show the presence of a leak easily. Other types of tests that could be used are cranial CT, cranial MRI, spinal MRI, and CT myelography. A cranial MRI can be diagnostic by showing one of the five main findings, which are subdural fluid collections, enhancement of venous structures, dural enhancement on MRI saggital views, pituitary hyperemia, and sagging of the brain. Another cause of<unk> s is postural<unk>  tachycardia syndrome (POTS), a form of dysautonomia, which is diagnosed with autonomic testing instead of the imaging tests that are used to determine a CSF leak. It can be difficult to distinguish if a patient is solely affected by POTS because patients with CSF leaks have similar symptoms and may even develop secondary POTS.
