Vascular Calcifications
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 the wall of the internal carotid artery (in the carotid sulcus), usually in addition to calcifications in the neck. Considering the potential increased risk for stroke, we recommend that patients with CCA in the neck are referred to the physician for further testing (ultrasound). Occasionally, we only see intracranial calcification in the ICA without calcifications in the neck. What should be … Continue reading >>
Distinguishing of Pleomorphic Adenomas From Other Types of Parotid Tumors by Diffusion-Weighted MR Imaging
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 MRI seems to be a valuable tool for differentiating benign from malignant primary parotid gland tumors in fifty consecutive patients (1). We read with interest the recent article of the same group in the January 2009 issue of the AJNR (2). The authors reached one different conclusion in one hundred thirty-six patients with parotid tumors. They claimed that, DWI has … Continue reading >>

More on DWI of Head and Neck Lesions
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 included the orbits and you all are able to see in the illustration that accompanies this comment, the lesion has significantly restricted diffusion as expected for such a highly cellular and malignant tumor.… Continue reading >>
DWI for Head and Neck Lesions
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 use of DWI in the evaluation of parotid and thyroid glands lesions. Restricted diffusion has a high correlation with malignancy independent of the site of origin of tumors. It is obvious that DWI will play a significant future role in the evaluation of head and neck lesions.… Continue reading >>
