Glioblastoma multiforme presenting as postpartum depression: a case report.

J Med Case Rep 2018 Dec 20;12(1):374. Epub 2018 Dec 20.

Department of Neurosurgery, Carl Gustav Carus University Hospital, TU Dresden, Dresden, Germany.

Background: Alterations of mental status are characteristic of psychiatric disorders but may also result from a multitude of organic causes. Generally, physical examination and blood analysis are a part of basic psychiatric differential diagnostics, whereas more sophisticated procedures (for example, brain imaging) are applied only in cases with pathologic diagnostic findings. Our report challenges this approach by describing a case of glioblastoma multiforme presenting as postpartum depression without abnormalities in basic differential diagnostics. Read More

Utility of the claw sign in spine magnetic nuclear resonance with diffusion to differentiate Modic type I changes for degenerative disease versus infection.

J Spine Surg 2018 Sep;4(3):616-623

Neuroradiology Service, Central Military Hospital, Bogotá DC, Colombia.

Background: In 1988, Modic and his colleagues described changes in the subchondral bone marrow of the vertebral plates in patients with degenerative disease or other pathologies, which were observed in the nuclear magnetic resonance (NMR) of the spine and were subdivided into three patterns of signal changes, called Modic type I, Modic type II and Modic type III. The main differential diagnosis of the Modic I changes of the vertebral plates due to degenerative disease in spine NMR, is infection in its early stages. In their study in 2014, Patel and collaborators, using a protocol and the concept of diffusion in spine MRI, were able to demonstrate that by means of the "claw sing", a degenerative disease with Modic type I changes, can be differentiated from an infection in early stages.

The role of imaging in the skeletal involvement of mucopolysaccharidoses.

Ital J Pediatr 2018 Nov 16;44(Suppl 2):118. Epub 2018 Nov 16.

Neuroradiology Unit, University Hospital "Ospedali Riuniti di Ancona", Politecnica University of Marche, Ancona, Italy.

This article discusses the role of imaging modalities including radiography, multi-detector computed tomography, magnetic resonance imaging, and ultrasound in diagnosing and monitoring skeletal abnormalities in mucopolysaccharidoses (MPS). The advantages and disadvantages of these different imaging tools will be discussed, along with their feasibility in this class of patients. As the musculoskeletal involvement is common to all MPS and is one of the main reasons for seeking medical attention, an increased awareness among paediatricians, rheumatologists, orthopaedists, radiologists, and other musculoskeletal specialists on the possible spectrum of abnormalities observed could facilitate a timely diagnosis, an appropriate severity evaluation, and better management.

A pediatric neurologic assessment score may drive the eculizumab-based treatment of Escherichia coli-related hemolytic uremic syndrome with neurological involvement.

Pediatr Nephrol 2019 Mar 25;34(3):517-527. Epub 2018 Oct 25.

Pediatric Nephrology and Dialysis Unit, Pediatric Hospital "Giovanni XXIII", Bari, Italy.

Background: Thrombotic microangiopathy (TMA) is a clinical syndrome encompassing a large group of rare but severe disorders including thrombotic thrombocytopenic purpura (TTP) and both typical and atypical forms of hemolytic uremic syndrome (HUS). The key role of the complement system is well known in TTP and atypical HUS, but recent reports describe its involvement in the pathogenesis of HUS secondary to gastrointestinal infections due to Shiga toxin-producing Escherichia coli (STEC).

Methods: TMA mainly affects the kidney, but extra-renal complications are frequently described. Read More

Integration of Computed Tomographic Angiography Spot Sign and Noncontrast Computed Tomographic Hypodensities to Predict Hematoma Expansion.

Stroke 2018 Sep;49(9):2067-2073

J. P. Kistler Stroke Research Center (A.C., K.S., C.K., C.D.A., M.E.G., A.V., S.M.G., J.R., J.N.G.).

Background and Purpose- Noncontrast computed tomographic (CT) hypodensities represent an alternative to the CT angiography spot sign (SS) to predict intracerebral hemorrhage (ICH) expansion. However, previous studies suggested that these markers predicted hematoma expansion independently from each other. We investigated whether the integration of SS and hypodensity (HD) improved the stratification of ICH expansion risk. Read More

Semin Ultrasound CT MR 2018 Oct 6;39(5):425-440. Epub 2018 Jun 6.

Section of Neuroradiology, University of Cincinnati Medical Center.

Stroke is caused by occlusion of a medium- or large-sized vessel in the brain. The treatment with either intravenous or intra-arterial thrombolysis is based on an accurate and time-sensitive diagnosis. On clinical and imaging grounds a number of entities-seizures, toxic-metabolic, infectious, or demyelinating diseases-can mimic stroke. Read More

Spinal canal meningioma mimicking posterior fossa ischemia on CT perfusion: A CT perfusion pitfall.

Authors:
Houman Sotoudeh

Radiol Case Rep 2018 Oct 1;13(5):1069-1071. Epub 2018 Jun 1.

Neuroradiology Department, University of Alabama at Birmingham, JTN 333, 619 19th St S, Birmingham, AL 35294, USA.

The recent approach to treat acute stroke is to extend treatment window in patients with salvageable peri-infarct ischemia which increases the application of the perfusion imaging, specifically computed tomography perfusion (CTP). In this paper, I am presenting a case of left middle cerebral artery infarction which was evaluated by CTP under "code stroke." The patient had an incidental spinal canal meningioma which was out of field of view in CTP but mimicked right cerebellar ischemia on CTP. Read More

3D fluid attenuated inversion recovery (FLAIR) magnetic resonance imaging at different stages of otosclerosis.

Eur Arch Otorhinolaryngol 2018 Nov 6;275(11):2643-2652. Epub 2018 Sep 6.

ENT Audiology and Phoniatrics Unit, Department of Surgical, Medical, Molecular Pathology and Emergency Medicine, University of Pisa, Via Paradisa 2, 56100, Pisa, Italy.

Purpose: The aim of this work is to study otosclerotic patients by 3D-FLAIR (fluid attenuated inversion recovery) sequence magnetic resonance imaging (MRI) with and without Gadolinium administration (-/+ Gd), to understand whether there is a direct relationship between radiological findings at 3D FLAIR MRI sequences and some clinical features of otosclerosis, such as the presence and entity of sensorineural involvement, duration of disease, patient gender, and other factors.

Methods: 38 patients affected by different stages of unilateral or bilateral otosclerosis underwent 3D FLAIR MRI+/- Gd. 11 subjects with normal hearing, previously submitted to 3T MRI for other minor diseases, unrelated with otosclerosis, had been retrospectively enrolled as control group.

Consensus Statements by Korean Society of Interventional Neuroradiology and Korean Stroke Society: Hyperacute Endovascular Treatment Workflow to Reduce Door-to-Reperfusion Time.

Korean J Radiol 2018 Sep-Oct;19(5):838-848. Epub 2018 Aug 6.

Department of Neurology, Inha University Hospital, Incheon 22332, Korea.

Recent clinical trials demonstrated the clinical benefit of endovascular treatment (EVT) in patients with acute ischemic stroke due to large vessel occlusion. These trials confirmed that good outcome after EVT depends on the time interval from symptom onset to reperfusion and that in-hospital delay leads to poor clinical outcome. However, there has been no universally accepted in-hospital workflow and performance benchmark for rapid reperfusion. Read More
