Background: Posterior reversible encephalopathy syndrome (PRES) is a clinical syndrome with numerous etiologies, mostly characterized by magnetic resonance imaging (MRI) abnormalities in the posterior cerebral white and gray matter and acute neurological symptoms.
Aim: To examine the predisposing factors, clinical results, and radiological features of PRES in children diagnosed with malignancy.
Materials And Methods: The study included 20 patients (7 F/13 M) aged 4-16 years at the time of diagnosis who were diagnosed with malignancy and developed PRES during chemotherapy.

Background: An increase in choroid plexus (CP) volume may be associated with cognitive decline in older individuals without dementia. In this study, we aimed to clarify whether CP volume can serve as an imaging marker of cognitive decline, determine how strongly CP volume is associated with cognitive decline, and explore factors associated with CP volume in older adults.
Methods: We measured CP volume, brain parenchyma, and cerebrospinal fluid (CSF) spaces associated with disproportionately enlarged subarachnoid space hydrocephalus (DESH), an imaging feature of normal-pressure hydrocephalus, in community-dwelling older adults aged ≥ 65 years without dementia.

Background: Diffusion Tensor Image Analysis Along the Perivascular Space (DTI-ALPS) evaluates the glymphatic system in patients with idiopathic normal-pressure hydrocephalus (iNPH). However, white matter compression due to ventricular enlargement may affect the ALPS index. This study aimed to investigate the relationship among the ALPS index, white matter changes, and clinical symptoms in patients with iNPH.

Purpose: Epidemiological studies on idiopathic normal pressure hydrocephalus (iNPH) imaging markers and their normal values are scarce. This population-based study aimed to analyze several morphologic and volumetric iNPH-related imaging markers in a large sample, determining their distribution, diagnostic accuracy, suggested cut-offs, and associations with iNPH symptoms.
Methods: This cross-sectional study included 791 70 year olds, 40 with radiologically probable iNPH (iNPH) and 751 without iNPH features (reference).

Colpocephaly, a cause of hydrocephalus, is characterized by disproportionately enlarged occipital horns of the lateral ventricles. It is rarely seen in the older adults. Few cases were reported as colpocephaly in elderly individuals in the literature.

Purpose: Although dopamine transporter (DAT) imaging has been reported to be useful for differentiating idiopathic Normal Pressure Hydrocephalus (iNPH) from its mimics, the radiological findings of DAT imaging in iNPH have not been established. We investigated [I] N-ω-fluoropropyl-2β-carboxymethoxy-3β-(4-iodophenyl) nortropane (FP-CIT) single photon emission computed tomography (SPECT) images from patients with disproportionately enlarged subarachnoid-space hydrocephalus (DESH)-type iNPH to understand the characteristics of DAT images of iNPH.
Methods: We retrospectively collected 11 DESH-type iNPH patients without comorbidities who underwent FP-CIT SPECT imaging.

Unlabelled: PURPOSE : Phase contrast magnetic resonance imaging (PC-MRI) represents an opportunity to non-invasively investigate cerebral spinal fluid (CSF) flow in patients with idiopathic normal pressure hydrocephalus (iNPH). Studies in recent years have explored the diagnostic and prognostic value of PC-MRI derived parameters. This review aims to identify all PC-MRI studies of iNPH published since 2010, synthesise a review based on collated results, and analyse specific flow parameters identified in the selected studies.

Hodgkin's lymphoma is a malignancy of the lymphatic system that can rarely present with advanced-stage features such as spinal cord involvement and hypercalcemia. We present the case of a 63-year-old Caucasian male with advanced Hodgkin's lymphoma, presenting with hypercalcemia and symptoms resembling normal pressure hydrocephalus. The patient exhibited gait impairment, altered mental status, and urinary incontinence, forming the classic triad seen in normal pressure hydrocephalus.

Idiopathic normal pressure hydrocephalus is a widespread neurodegenerative disease of the elderly. If not treated surgically early, it results in a severe decrease in quality of life and disability. According to current clinical Russian and foreign guidelines the candidates for CSF shunting procedures are selected based on the results of invasive tests, though treatment outcomes are not always optimal.

Background: Reduced cerebrospinal fluid (CSF) clearance may play a vital role in the pathogenesis of normal pressure hydrocephalus (NPH), but the radiologic marker is yet to be elucidated.
Objectives: This open-label study presents two novel neuroimaging biomarkers based on enlarged perivascular spaces (ePVS) of the sub-insular territory: the Hedgehog and Hedgehog-Halo (H-H) sign, designed to predict gait symptom severity and tap response in NPH.
Methods: We retrospectively reviewed 203 patients with possible NPH with baseline magnetic resonance imaging and gait analyses before and after lumbar puncture (LP).

Purpose;Lumboperitoneal shunting (LPS) is a common procedure for treating idiopathic normal pressure hydrocephalus (iNPH), involving two abdominal approaches:anterior abdominal laparotomy and lateral abdominal laparotomy (LAL). While LAL is advantageous in terms of infection risk, it presents challenges such as muscle manipulation and potential deviation from the desired trajectory. This report presents a novel technique that utilizes ultrasound examination of the lateral abdominal wall (UELAW) to visualize the three muscle layers (external oblique, internal oblique, and transversus abdominis) before abdominal manipulation during LAL.

Pathological gait in patients with Hakim's disease (HD, synonymous with idiopathic normal-pressure hydrocephalus; iNPH), Parkinson's disease (PD), and cervical myelopathy (CM) has been subjectively evaluated in this study. We quantified the characteristics of upper and lower limb movements in patients with pathological gait. We analyzed 1491 measurements of 1 m diameter circular walking from 122, 12, and 93 patients with HD, PD, and CM, respectively, and 200 healthy volunteers using the Three-Dimensional Pose Tracker for Gait Test.
