Teaching NeuroImages: Cortical blindness following acute obstructive hydrocephalus by a colloid cyst
A 46-year-old woman was admitted for acute headache, postseizure confusion, and visual loss. Urgent head CT scan showed obstructive hydrocephalus due to a colloid cyst (figure 1). External ventricular drains inserted emergently demonstrated CSF under pressure, above 40 mm H2O. MRI confirmed the suspected diagnosis of a colloid cyst and highlighted bilateral occipital lobe infarcts (figure 2). CT angiography showed no thrombosis of the posterior cerebral arteries (PCAs). After neurosurgical excision of the colloid cyst, the patient remained blind. The presumed mechanism of infarction was acute compression of the PCAs agains...

Unusual Post-COVID-19 Presentation With Tetraventricular Hydrocephalus: A Case Report
Discussion Fourth ventricular outlet obstruction is a rare cause of tetraventricular HCP. In most cases, it is associated with a history of inflammatory conditions or hemorrhage. In our case, a history of recent COVID-19 infection and normal imaging before COVID-19 make COVID-19 the most probable explanation for HCP. We suggest considering COVID-19 infection in the differential diagnosis of HCP of unclear etiology.

What Clinical Signs Can Be Associated With Benign External Hydrocephalus?
Discussion Hydrocephalus is an abnormal accumulation of cerebrospinal fluid (CSF) in the ventricles and/or subarachnoid spaces. External hydrocephalus is a communicating hydrocephalus often defined as the patient having a rapidly enlarging head circumference (HC) and enlargement of the subarachnoid spaces especially over the frontal lobes with normal or moderately enlarged ventricles. Benign external hydrocephalus (BEH) is a self-limited external hydrocephalus that occurs during infancy and resolves spontaneously in childhood, usually by age 2 years, that is felt to not cause significant problems. It was first described by...

Can Shunt Response in Patients with Idiopathic Normal Pressure Hydrocephalus Be Predicted from Preoperative Brain Imaging? A Retrospective Study of the Diagnostic Use of the Normal Pressure Hydrocephalus Radscale in 119 Patients ADULT BRAIN
CONCLUSIONS: The Normal Pressure Hydrocephalus Radscale showed moderate discrimination for shunt response but cannot, on its own, be used for selecting patients with idiopathic normal pressure hydrocephalus for shunt surgery.

Factors Associated Postoperative Hydrocephalus in Patients with Traumatic Acute Subdural Hemorrhage.
Conclusion: In patients with acute traumatic SDH with coexisting IVH, a large amount of SDH, and a larger midline shift, close follow-up is necessary for the early prediction of postoperative hydrocephalus. Furthermore, craniectomy margin need not be limited in acute traumatic SDH patients for the reason of postoperative hydrocephalus. PMID: 29142634 [PubMed]

Hydrocephalus Growth: Definition, Prevalence, Association with Poor Outcome in Acute Intracerebral Hemorrhage
ConclusionsHydrocephalus growth is defined by strongly predictive of short- or long-term mortality and poor outcome at 90  days, and might be a potential indicator for assisting clinicians for clinical decision-making.

Changes in computed tomography perfusion parameters and maximum contrast enhancement in patients having hydrocephalus with a ventriculoperitoneal shunt: a pilot study
CONCLUSIONS: Perfusion changes in patients with hydrocephalus after VP shunt were seen in the FWM and BG, which appears to be the result of the hydrocephalus reducing brain perfusion in the deep part of the brain. We concluded that SAH slows brain perfusion recovery.PMID:34781783 | DOI:10.1177/02841851211038807

Volumetric quantification of aneurysmal subarachnoid hemorrhage independently predicts hydrocephalus and seizures.
CONCLUSIONS: Hemorrhage volume is an independent predictor of seizures and shunt-dependent hydrocephalus in patients with aSAH. Further evaluation of aSAH quantitative volumetric analysis may complement existing scales used in clinical practice and assist in patient prognostication and management.

Transient Obstructive Hydrocephalus due to Intraventricular Hemorrhage: A Case Report and Review of Literature.
CONCLUSIONS: In patients with IVH, acute obstructive hydrocephalus can develop at any time after the ictus. Though a delayed presentation of acute but transient obstructive hydrocephalus is unusual, it is important to be aware of this scenario and ensure that deterioration secondary to thrombus migration and subsequent obstructive hydrocephalus do not occur.

Acute communicating hydrocephalus after intracranial arachnoid cyst decompression: A report of two cases
CONCLUSION: Acute development of hydrocephalus is a potential complication of intracranial AC fenestration. A better understanding of intracranial cerebrospinal fluid flow dynamics may better inform as to the underlying cause of this complication.PMID:34754583 | PMC:PMC8571241 | DOI:10.25259/SNI_712_2021
