The benefits of radiological imaging for postoperative orthostatic headache: a case report

Abstract

Background Traditionally, the diagnosis of post-dural puncture headache (PDPH) relied upon the patient’s history regarding dural puncture and symptoms, such as orthostatic headache. However, such evidence may not always be reliable or specific. We report an unexpected diagnosis with spontaneous intracranial hypotension (SIH), which was confirmed upon examination of Magnetic Resonance (MR) images in a patient who was initially suspected to have PDPH because he had recently undergone a uncertain dural puncture. Case presentation A 45-year-old man had undergone a thoracic epidural catheter insertion for perioperative analgesia prior to general anesthesia induction. Due to intermittent dripping of fluid while the epidural needle was being advanced, a dural puncture was suspected. The patient complained of an orthostatic headache after recovery from surgery, therefore a PDPH was suspected. MR images revealed signs of SIH: dural sinus engorgement, contrast enhancement along the neural sleeves of the left C6–7, bilateral C7-T1, T1–2, T2–3, T3–4, T4–5, and T5–6. Computed tomography-guided epidural blood patching (EBP) was performed the following day, with the patient experiencing immediate relief of the headache. Conclusion The benefits of radiological imaging in this case included confirming the correct diagnosis, guiding the accurate level and proper approach of EBP, distinguishing the epidural space from the intrathecal space, and ultimately increasing the likelihood of successful EBP.

Dural tear from diagnostic lumbar puncture followed by long-term morbidity: a case report

“…Symptomatic epidural collections was reported in one pediatric population [9], and further we have identified one adult case report describing severe PDPH and CSFleak after epidural anesthesia, but in this case a distant unrelated dural leak was identified and assumed causal [10].…”
