Arachnoid cysts do not contain cerebrospinal fluid: A comparative chemical analysis of arachnoid cyst fluid and cerebrospinal fluid in adults
Berle, Magnus; Wester, Knut; Ulvik, Rune Johan; Kroksveen, Ann Cathrine; Haaland, Øystein; Amiry-Moghaddam, Mahmood; Berven, Frode S. (Peer reviewed; Journal article, 2010-06-10)Background Arachnoid cyst (AC) fluid has not previously been compared with cerebrospinal fluid (CSF) from the same patient. ACs are commonly referred to as containing "CSF-like fluid". The objective of this study was to ... -
Benign external hydrocephalus: a review, with emphasis on management
Zahl, Sverre Morten; Egge, Arild; Helseth, Eirik; Wester, Knut (Peer reviewed; Journal article, 2011-06-07)Benign external hydrocephalus in infants, characterized by macrocephaly and typical neuroimaging findings, is considered as a self-limiting condition and is therefore rarely treated. This review concerns all aspects of ... -
Difficult birth is the main contributor to birth‐related fracture and accidents to other neonatal fractures
Högberg, Ulf; Fellman, Vineta; Thiblin, Ingemar; Karlsson, Ruth; Wester, Knut (Journal article; Peer reviewed, 2020)Aim Specific birth-related fractures have been studied; underestimates might be a problem. We aimed to assess all fractures diagnosed as birth-related as well as other neonatal fractures. Methods A population-based ... -
Epidemiology of benign external hydrocephalus in Norway - a population-based study
Wiig, Ulrikke S.; Zahl, Sverre Morten; Egge, Arild; Helseth, Eirik; Wester, Knut (Peer reviewed; Journal article, 2017-08)Background: Benign external hydrocephalus is defined as a rapidly increasing head circumference (occipitofrontal circumference) with characteristic radiological findings of increased subarachnoid cerebrospinal fluid spaces ... -
Examining perinatal subdural haematoma as an aetiology of extra-axial hygroma and chronic subdural haematoma
Zahl, Sverre Morten; Wester, Knut; Gabaeff, Steven (Peer reviewed; Journal article, 2020)Aim: Benign external hydrocephalus (BEH), hygroma and chronic subdural haematoma are extra‐axial fluid collections in infants. MRI studies have shown that almost half of all new‐borns have perinatal subdural blood, generally ... -
External Hydrocephalus as a Cause of Infant Subdural Hematoma: Epidemiological and Radiological Investigations of Infants Suspected of Being Abused
Andersson, Jacob; Wikström, Johan; Högberg, Ulf; Wester, Knut; Thiblin, Ingemar (Journal article; Peer reviewed, 2022)Background Acute subdural hematoma (ASDH) and chronic subdural hematoma (CSDH) in infants have been regarded as highly specific for abuse. Other causes of CSDH have not been investigated in a large population. Purpose The ... -
Intracranial arachnoid cysts: impairment of higher cognitive functions and postoperative improvement
Gjerde, Priyanthi Borgen; Schmid, Marit Therese; Hammar, Åsa; Wester, Knut (Peer reviewed; Journal article, 2013-08-28)Background Intracranial arachnoid cysts have been shown to yield cognitive impairment over a range of basic mental functions, and these functions normalize after surgical cyst decompression. We wanted to investigate whether ... -
Is external hydrocephalus a possible differential diagnosis when child abuse is suspected?
Scheller, Joseph; Wester, Knut (Journal article; Peer reviewed, 2021)Background: Criteria for diagnosing abusive head trauma (AHT) or “shaken baby syndrome” are not well defined; consequently, these conditions might be diagnosed on failing premises. Methods: The authors have collected a ... -
Microarray-based gene expression profiling and DNA copy number variation analysis of temporal fossa arachnoid cysts
Aarhus, Mads; Helland, Christian Andre; Lund-Johansen, Morten; Wester, Knut; Knappskog, Per (Peer reviewed; Journal article, 2010-02-26)Background Intracranial arachnoid cysts (AC) are membranous sacs filled with CSF-like fluid that are commonly found in the temporal fossa. The majority of ACs are congenital. Typical symptoms are headache, dizziness, and ... -
Protein profiling reveals inter-individual protein homogeneity of arachnoid cyst fluid and high qualitative similarity to cerebrospinal fluid
Berle, Magnus; Kroksveen, Ann Cathrine; Haaland, Øystein; Aye, Thin T.; Opsahl, Jill Anette; Oveland, Eystein; Wester, Knut; Ulvik, Rune Johan; Helland, Christian Andre; Berven, Frode S. (Peer reviewed; Journal article, 2011-05-20)Background: The mechanisms behind formation and filling of intracranial arachnoid cysts (AC) are poorly understood. The aim of this study was to evaluate AC fluid by proteomics to gain further knowledge about ACs. Two goals ... -
Quality of life and physician-reported developmental, cognitive, and social problems in children with benign external hydrocephalus—long-term follow-up
Zahl, Sverre Morten; Egge, Arild; Helseth, Eirik; Skarbø, Anne-Britt; Wester, Knut (Peer reviewed; Journal article, 2019-02)Introduction: Benign external hydrocephalus (BEH) is characterized by too rapidly increasing head circumference in infants, combined with typical neuroimaging findings. Psychomotor developmental delay is typically seen ... -
Quantitative proteomics comparison of arachnoid cyst fluid and cerebrospinal fluid collected perioperatively from arachnoid cyst patients
Berle, Magnus; Kroksveen, Ann Cathrine; Garberg, Hilde Kristin; Aarhus, Mads; Haaland, Øystein; Wester, Knut; Ulvik, Rune Johan; Helland, Christian Andre; Berven, Frode S. (Peer reviewed; Journal article, 2013-04-29)Background: There is little knowledge concerning the content and the mechanisms of filling of arachnoid cysts. The aim of this study was to compare the protein content of arachnoid cysts and cerebrospinal fluid by quantitative ... -
Reference ranges for head circumference in ethiopian children 0-2 years of age
Amare, Ephrem Bililigne; Idsøe, Mari; Wiksnes, Miriam; Moss, Thomas; Roelants, Mathieu; Shimelis, Damte; Juliusson, Petur Benedikt; Kiserud, Torvid; Wester, Knut (Peer reviewed; Journal article, 2015-12)BACKGROUND: Head circumference (HC) charts are important for early detection of hydrocephalus during childhood. In low-income countries where populationbased HC charts are rarely available, hydrocephalus occurs more commonly ... -
Retinal haemorrhage in infants investigated for suspected maltreatment is strongly correlated with intracranial pathology
Thiblin, Ingemar; Andersson, Jacob; Wester, Knut; Högberg, Göran; Högberg, Ulf (Journal article; Peer reviewed, 2021)Aim To test the two prevailing hypotheses regarding the aetiology of infant retinal haemorrhage: (a) traction forces exerted by the lens and/or corpus vitreum on the retina during infant shaking or (b) retinal vessel ... -

Zahl, Sverre Morten; Mack, Julie A.; Rossant, Cyrille; Squier, Waney; Wester, Knut (Journal article; Peer reviewed, 2021)Aim: Thrombosis of bridging veins has been suggested to be a marker of bridging vein rupture, and thus AHT, in infants with subdural haematoma. Methods: This is a non-systematic review based on Pubmed search, secondary ... -
