Background To analyse the clinical characteristics of COVID-19 with acute ischaemic stroke (AIS) and identify factors predicting functional outcome. Methods Multicentre retrospective cohort study of COVID-19 patients with AIS who presented to 30 stroke centres in the USA and Canada between 14 March and 30 August 2020. The primary endpoint was poor...

A large number of disease processes can involve the orbits and produce nonspecific signs and symptoms, including pain, proptosis, vision loss, and ophthalmoplegia. Further, adequate ophthalmologic assessment may be challenging in patients in the acute setting, such as those presenting with severe trauma. This is particularly relevant in the pediatr...

Gliomatosis Cerebri (GC) is a rareand rapidly progressive pattern of growth of diffusely infiltrating gliomas with limited treatment options. Imaging findings are usually nonspecific and can mimic other neurologic disorders, including demyelination, encephalitis, and multicentric/multifocal glioma. In this report, we describe a case of a 53-year-ol...

Sarcoidosis is an idiopathic multisystem granulomatous disease that affects patients of all races and ethnic groups however predilection for women and African Americans is apparent. Extrapulmonary manifestations of sarcoidosis occur in up to 50% of cases. The most common sites of extrapulmonary involvement are the skin, eyes, liver, and reticuloend...

Fluoroscopic-guided lumbar puncture (LP) is a procedure commonly performed by radiologists, which in some circumstances may be difficult or impossible using a traditional posterior interspinous or interlaminar approach. Alternatives to LP include cervical and cisternal punctures, placement of an Ommaya reservoir, and lumbar laminectomy. More recent...

Pineal glioblastoma is an exceedingly rare potential etiology for a pineal region mass. The presentation, imaging appearance, and changes in treatment have been documented in a select number of cases since its first description in 1954. Through these cases, changes in treatment have shown to improve outcomes in select patients, some of which have h...

The ability to localize the three spinal tracts (corticospinal tract, spinothalamic tract, and dorsal [posterior] columns) involved in incomplete spinal cord syndromes at cross-sectional imaging and knowledge of the classic clinical manifestations of the various syndromes enable optimized imaging evaluation and provide clinicians with information t...

Spontaneous intracranial hypotension Systemic lupus erythematous CSF leak Pachymeningeal enhancement Venous engorgement CT myelography a b s t r a c t Spontaneous intracranial hypotension (SIH) associated with cerebrospinal fluid leak classically presents with postural headache. It is most commonly caused by the spontaneous dehiscence of a meningea...

Background Neuromyelitis Optica Spectrum disorders (NMOSD) is a rare autoimmune disease characterized by optic neuritis (ON) and/or longitudinal extensive transverse myelitis (LETM). It is commonly associated with other autoimmune diseases (OAD). Recent reports suggested racial differences in clinical phenotype and presentation of NMOSD. However, d...

Objective: Rare disease Background: Gradenigo’s syndrome includes the triad of suppurative otitis media, ipsilateral sixth (abducens) cranial nerve palsy and facial pain in the distribution of the fifth (trigeminal) cranial nerve. Gradenigo’s syndrome is rare, and the diagnosis is easily overlooked. This case is the first to report Gradenigo’s synd...

Sinusitis is a common disease. Complications, however, are less common and can be life threatening. Major complications occur from extension of disease into the orbit and intracranial compartment and often require emergent treatment with intravenous antibiotics or operative intervention. Immunocompromised patients with acute sinusitis are susceptib...

PURPOSE CT time is paramount in triaging acute stroke patients receiving IV thrombolysis, which must be performed within 3 hours of symptom onset. We critique our experience as a designated NYS Stroke Center, emphasizing potential areas for improvement in "door-to-CT" time. METHOD AND MATERIALS We reviewed the clinical and radiological findings of...

We attempted to investigate whether computed tomography pulmonary angiography (CTPA) in the expiratory phase can improve contrast enhancement of the pulmonary arteries and mitigate the effect of inspiratory transient attenuation artifact, potentially salvaging nondiagnostic studies. Eighteen patients with indeterminate inspiratory CTPA, despite pro...

PURPOSE/AIM 1) Discuss MR imaging technique (e.g. pulse sequences, use of direct and indirect arthrography and MR neurography) 2) Identify common injuries in different sports, emphasizing throwing athletes 3) Discuss normal anatomy, key structural components of each compartment, variants and appearance on MRI 4) Outline an approach to examining the...

PURPOSE/AIM 1) Describe pathophysiology and epidemiology of hemangioma and illustrate typical features of hemangioma on different imaging modalities, including CT and dynamic MR. 2) Discuss how the specific features seen on each modality allow for specific diagnosis of hemangioma and its variants. 3) Expand upon current interventional treatment opt...
