We report magnetic resonance (MR), computed tomography (CT) and angiographic imaging of an unusual giant arachnoid granulation in the superior sagittal sinus in a man with headache and vertigo. Intrasinus pressure measurements revealed a significant pressure gradient across the lesion. MR imaging is useful to identify giant arachnoid granulation and dural sinus thrombosis, whereas dural sinus pressure measurement in certain cases of giant arachnoid granulations can be used to evaluate the lesion as the cause of the patient's symptoms.

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 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.

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.
