- Neurologic Involvement in COVID-19: Cause or Coincidence? A Neuroimaging Perspective
Despite a large cohort of 103 patients with COVID-19, the authors found a large number of symptomatic patients with negative neuroimaging findings, and no conclusions can be drawn concerning concrete associations between neuroimaging and COVID-19.
- Cerebral Venous Thrombosis Associated with COVID-19
The authors report a unique series of young patients with COVID-19 presenting with cerebral venous system thrombosis. Three patients younger than 41 years of age with confirmed Severe Acute Respiratory Syndrome coronavirus 2 infection had neurologic findings related to cerebral venous thrombosis.
- Indentation and Transverse Diameter of the Meckel Cave: Imaging Markers to Diagnose Idiopathic Intracranial Hypertension
The purpose of this study was to investigate whether the shape (bilobed or indented appearance of the Meckel cave) or the size/volume of the Meckel cave on T2-weighted MRI could serve as a noninvasive diagnostic imaging marker for the diagnosis of idiopathic intracranial hypertension. The authors studied 75 patients with a diagnosis of IIH and 75 age-and sex-matched healthy controls. The transverse diameter of the Meckel cave was measured in the axial and coronal planes of T2-weighted MRI, and comparison was made between the 2 groups. Of 75 patients with an approved diagnosis of IIH, 57 (76%) showed an indented Meckel cave as opposed to 21 (28%) in the control group. They conclude that the shape and size of the Meckel cave can be used as sensitive and specific diagnostic imaging markers for the diagnosis of IIH.
