Nonadjustable state of programmable shunt valve: obstruction of middle cranial fossa arachnoid cyst-peritoneal shunt.
Chin Neurosurg J
December 2024
Department of Neurosurgery, Hebei Children's Hospital, Hebei Medical University, Shijiazhuang, Hebei, China.
Background: A nonadjustable state of the programmable shunt valve is a rare phenomenon. This case report aims to explore the cause of pressure adjustment dysfunction in a programmable shunt valve in a middle cranial fossa arachnoid cyst-peritoneal shunt patient and to underscore this dysfunction as an indicator of shunt valve obstruction.
Case Presentation: A child with a ruptured giant arachnoid cyst in the left middle cranial fossa presented with acute intracranial hypertension following head trauma.
Arachnoid granulations: Dynamic nature and review.

Arachnoid granulations have been known for centuries yet remain incompletely understood. While traditionally associated with cerebrospinal fluid transport, the precise mechanism remains uncertain. This manuscript reviews the literature on the anatomy, histology, and imaging findings of arachnoid granulations and their mimickers and anomalous variations.

December 2024
Division of Pediatric Neurosurgery, Department of Neurosurgery, Faculty of Medicine, Gazi University, Ankara, Turkey.
Background: Arachnoid cysts are extra parenchymal, intra-arachnoid fluid collections of unknown origin, similar in content to cerebrospinal fluid. Suprasellar arachnoid cysts are a rarer localization resulting from abnormalities of the Liliequist membrane or cystic dilatation of the interpeduncular cisterna. We aimed to contribute to the literature by presenting a series of suprasellar arachnoid cyst cases with endoscopic intervention and long-term results.

Division of Neurosurgery, Department of Surgery, Brawijaya University/Dr Saiful Anwar General Hospital, Malang, East Java, Indonesia.
Article Synopsis
- Schwannomas are benign tumors typically found near spinal nerve roots, but large cases with cystic degeneration are difficult to diagnose before surgery and are not well-researched in medical literature.
- A case is presented of a 28-year-old man with a giant schwannoma causing intermittent pain in his left thigh; MRI revealed a complex cystic lesion extending from L4 to S1.
- Successful surgical removal of the tumor led to symptom resolution, highlighting the need for accurate diagnosis through MRI and histopathology, and emphasizing that complete surgical excision is the preferred treatment approach.
Giant intracranial arachnoid cyst in an outstanding soldier.

Department of Medical Imaging, Chinese People's Armed Police Force Hospital of Beijing, Beijing, China.
Article Synopsis
- The article discusses a unique case of a soldier with a large intracranial arachnoid cyst that surprisingly did not affect his performance or abilities.
- Despite the cyst compressing the brain into the opposite side of the skull, the soldier exhibited no major clinical symptoms.
- This case highlights the remarkable adaptability and plasticity of brain tissue, as the patient maintained excellent motor and cognitive functions.
