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.

Background: Mechanical thrombectomy (MT) in association with intravenous thrombolysis is recommended for treatment of acute ischemic stroke (AIS), with large vessel occlusion (LVO) in the anterior circulation. Because MT is only available in comprehensive stroke centers (CSC), the challenge of stroke organization is to ensure equitable access to the fastest endovascular suite. Our aim was to evaluate the feasibility, efficacy, and safety of MT in patients initially managed in 1 CSC (mothership), compared with patients first managed in primary stroke center (PSC), and then transferred to the CSC for MT (drip-and-ship).

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.

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
