Spinal-cerebrospinal fluid leak demonstrated by radiopharmaceutical cisternography

Area of Science:

• Neurosurgery
• Radiology
• Neurology

Background:

• Cerebrospinal fluid (CSF) leaks can arise from various iatrogenic or traumatic causes, including spinal procedures and injuries.
• Spontaneous spinal CSF leaks are increasingly recognized as a significant cause of spontaneous intracranial hypotension.
• These leaks most commonly occur at the cervicothoracic junction or thoracic spine and are often self-limiting.

Observation:

• Traditional diagnostic methods for CSF leaks include detecting radioactivity outside the subarachnoid space or observing rapid tracer disappearance and bladder appearance.
• This paper presents two rare cases of spontaneous cerebrospinal fluid leaks.
• The diagnosis in these unusual cases was established using radiopharmaceutical cisternography.

Findings:

• Radiopharmaceutical cisternography proved effective in identifying unusual cases of cerebrospinal fluid leaks.
• The presented cases demonstrate the utility of this imaging technique in diagnosing less common presentations of CSF leaks.
• Diagnostic imaging is crucial for confirming the location and extent of cerebrospinal fluid loss.

Implications:

• Accurate diagnosis of CSF leaks is essential for appropriate management and to alleviate symptoms of intracranial hypotension.
• Radiopharmaceutical cisternography offers a valuable tool for diagnosing challenging and uncommon CSF leak cases.
• Further research into the etiology and diagnostic modalities for spontaneous CSF leaks is warranted.
