We present two cases of cystic lesions in the Meckel’s cave, both of which showed fluid-fluid levels on MR images and are consistent with trigeminal cystic schwannomas. Fluid-fluid levels are the result of mucinous areas or microcysts, or as a result

This month (Feb. 2009), there is an article in AJNR regarding differentiating cold thryoid nodules as benign vs. malignat on DWI. link: http://www.ajnr.org/cgi/content/full/30/2/417. A similar article by Bozgeyik et al (abstract below) appeared in the March 2009 issue of ‘Neuroradiology’
Here’s another case for the value of DWI for head and neck lesions. This patient had left central retinal artery occlusion and acute ischemic optic neuropathy. There is restricted diffusion in the anterior left optic nerve which is much more
I would really appreciate your opinions on the following. We see calcified carotid atheromas (CCA) in the neck on a regular basis as incidental findings in (maxillofacial) cone-beam CT scans of our patients. Sometimes we also see intracranial calcification in
Until now, many articles have been published to declare that apparent diffusion coeficient calculation (ADC) by diffusion-weighted imaging (DWI) is a helpful method for differantiating malignant from benign parotid gland tumors. Habermann et al. in 2005 described that diffusion-weighted echo-planar
Has anyone ever actually seen a case of ethmoid artery injury and retraction leading to a post septal hematoma? my FESS guys say it is actually extremely rare, does everyone comment on aeration of the anterior and posterior ethmoid artery
Yesterday I wrote a short comment in the utility of DWI in the evaluation of head and neck lesions. While reading cases in the afternoon I came across a new patient with a retinoblastoma. This patient had DWI images that
In the January issue of AJNR you will find a nice article on the use of DWI for differentiating between orbital inflammatory and lymphoid lesions. Other articles, already published in AJNR or listed in our publication preview section describe the
