RESUMO
The Neck Imaging Reporting and Data System (NI-RADS) is a guide developed and introduced in 2017 by head and neck radiologists who worked in an academic radiology department. Based on the Breast Imaging Reporting and Data System, the initial goals of NI-RADS were to make posttreatment head and neck cancer imaging dictations more succinct and efficient, guide treating physicians in the next appropriate steps when recurrence was suspected, and encourage institutional and national research. NI-RADS is more than a dictation template, and it is best instituted after a head and neck imaging practice is established. We support the use of NI-RADS once a radiologist understands the nuances of head and neck cancer, including the biology, common subsites involved, essentials of tumor staging, common posttreatment benign imaging appearances, and subtleties of recurrent disease.

The association of syringomyelia and extramedullary spinal cord tumors is rare. We present the case of a patient with this association documented by magnetic resonance imaging and discuss the unusual features of the syrinx.

We report the case of a 19-year-old man harboring a pineal region dermoid, of which only eight other cases have been reported. A diagnosis was made with magnetic resonance imaging (MRI), which showed a marked high signal intensity on both T-1 and T-2 weighted images that is consistent with the lipid character of the lesion. Residual tumor could be seen on postoperative MR images. MRI is an accurate, noninvasive modality for the diagnosis and follow-up evaluation of these tumors.

Progressive hypersomnia, memory disturbance, and vertical ophthalmoplegia developed in a 63-year-old woman. The diagnosis of Whipple's disease of the central nervous system was suggested by her presentation and results of studies using magnetic resonance imaging. Despite a one-month course of antibiotics, active Whipple's disease, localized to the central nervous system, was found at autopsy.
