A 24-year-old woman experienced a postdural puncture headache following a labor epidural, recovered following bedrest, and was then without headache for 12 years. She then experienced sudden onset of daily, holocephalic headache persisting for 6 years prior to presentation. Pain reduced with prolonged recumbency. MRI brain, MRI myelography, and later bilateral decubitus digital subtraction myelography showed no cerebrospinal fluid (CSF) leak or CSF venous fistula, and normal opening pressure. Review of an initial noncontrast MRI myelogram revealed a subcentimeter dural outpouching at L3-L4, suspicious for a posttraumatic arachnoid bleb. Targeted epidural fibrin patch at the bleb resulted in profound but temporary symptom relief, and the patient was offered surgical repair. Intraoperatively, an arachnoid bleb was discovered and repaired followed by remission of headache. We report that a distant dural puncture can play a causative role in the long delayed onset of new daily persistent headache.

The cerebrospinal fluid spaces of the spine and brain are an intricate network of tissues with complex anatomic relationships. Understanding the normal imaging anatomy and variants of these spaces is crucial for accessing the spinal subarachnoid space and evaluating patients with suspected CSF leaks. This article reviews the imaging anatomy of the cerebrospinal fluid spaces in the spine and brain with emphasis on clinically relevant anatomy for percutaneous needle access to the spinal subarachnoid space and management of patients with CSF leak.

Blister aneurysms (BA) are high-risk cerebrovascular lesions accounting for 1% of intracranial aneurysms. The defective vessel wall and broad-based neck make this clinical entity difficult to treat, with high rates of re-rupture and mortality in patients presenting with acute subarachnoid haemorrhage. Blister aneurysms pose substantial challenges for both endovascular and microsurgical management.

Background: We describe a case of long-standing intracranial hypotension caused by an iatrogenic arachnoid diverticulum. This case illustrates two learning points. First, excessive CSF absorption may occur through an acquired arachnoid-epidural venous plexus at a dural defect.
