“…A cerebral pial arteriovenous fistula (PAVF) is a direct connection between the intracranial artery and vein without a nidus, and the vein often develops venous pouches of different sizes. Cerebral PAVF can occur during the early months of life in any location in the brain but are most commonly found in the supratentorial region 93 . Cerebral PAVF involving the AChA is extremely rare but not unheard of.…”

The anterior choroidal artery (AChA) is a critical artery in brain physiology and function. The AChA is involved in many diseases, including aneurysm, brain infarct, Moyamoya disease (MMD), brain tumor, arteriovenous malformation (AVM), etc. The AChA is vulnerable to damage during the treatment of these diseases and is thus a very important vessel. However, a comprehensive systematic review of the importance of the AChA is currently lacking. In this study, we used the PUBMED database to perform a literature review of the AChA to increase our understanding of its role in neurophysiology. Although the AChA is a small thin artery, it supplies an extremely important region of the brain. The AChA consists of cisternal and plexal segments, and the point of entry into the choroidal plexus is known as the plexal point. During treatment for aneurysms, tumors, AVM or AVF, the AChA cisternal segments should be preserved as a pathway to prevent the infarction of the AChA target region in the brain. In MMD, a dilated AChA provides collateral flow for posterior circulation. In brain infarcts, rapid treatment is necessary to prevent brain damage. In Parkinson disease (PD), the role of the AChA is unclear. In trauma, the AChA can tear and result in intracranial hematoma. In addition, both chronic and non-chronic branch vessel occlusions in the AChA are clinically silent and should not deter aneurysm treatment with flow diversion. Based on the data available, the AChA is a highly essential vessel.

“…[ 1 ] The most important anatomical feature is the direct connection between the intracranial arterial system and the venous system of the Willis ring or its secondary branch vessels. [ 4 , 5 ] PAVF can cause headaches, intracranial hemorrhages, seizures, and focal neurological deficits; hemorrhages generally manifest as intracranial hematoma or subarachnoid hemorrhage. [ 3 , 4 ] In this case, the patient had a ruptured PAVF with a large thrombus.…”

Introduction: Pial arteriovenous fistula (PAVF) is a rare intracranial vascular disease, and its presentation with a huge tumor-resembling thrombus is rarer. Patient concerns: A 38-year-old female patient presented with a sudden left-side motor disorder and loss of consciousness. The patient was otherwise in good health and had no history of hypertension or diabetes. During the physical examination, she appeared lethargic and manifested left limb paralysis with level zero muscle strength and a positive pathological reflex. Diagnoses: Because imaging failed to rule out a tumor stroke, an intracranial lesion resection was performed immediately. Because the lesion was considered to be a vascular structure, digital subtraction angiography was undertaken before the surgery, and PAVF was diagnosed. Interventions: Endovascular embolization was conducted, followed by PAVF and hematoma resection. Outcomes: At the 3-month follow up, her left limb muscle strength was level 4, and she could live on her own (Modified Rankin Scale score = 2). Conclusions: It is noteworthy that PAVF with a large thrombus may appear as a tumor in the initial diagnosis, and therefore it is necessary to perform an intracranial vascular examination in patients with tumor stroke symptoms.

“…Intracranial pial arteriovenous fistula (IPAVF) is a group of infrequently occurring vascular malformation in children [1][2][3][4][5][6][7]. IPAVF represents a subpial vascular malformation with high-flow shunt fed by mostly one or more pial arterial feeders and drainage by a solitary vein and lacking nidus [1,3,4].…”

Background and Importance: Intracranial pial arteriovenous fistula is a recently described matter as a rare vascular malformation occurring in children. It is usually located in the subpial space in the intracranial cavity with a high-flow shunt. Case Presentation: Authors report on a 2-year-old child with intracranial pial arteriovenous fistula and progressive enlargement of head and seizures mimicking progressive obstructive hydrocephalus for eight months. Cranial computed tomography showed a hyperdense midline vein of Galen and enlarged straight sinus associated with obstructive hydrocephalus. Presence of an aneurysm of the vein of Galen was suspected. Conclusion: Authors believe that cranial screening with computed tomography for suspected early diagnosis is of high importance.
