19 godz. temu · The classic imaging appearances of acute and chronic sinonasal infectious/inflammatory processes are described in this chapter with a discussion of important clinical considerations and complications. Critical imaging findings such as orbital and intracranial involvement are covered in detail. Manifestations of sinonasal disease in the setting ...
12 wrz 2024 · The distinctive molecular and genetic characteristics of sinonasal tumors have become better understood, and radiologists must be aware of these findings to fully participate in multidisciplinary discussions and help guide appropriate diagnosis and therapy.
14 lut 2019 · This article aims to briefly review the histopathologic classifications of sinonasal tumors as well as provide imaging examples and reported imaging characteristics of these new and emerging entities.
This article presents the imaging findings in some of the most common benign and malignant sinonasal tumours, and the TNM classification and staging of sinonasal carcinomas. Keywords: Head, neck, sinonasal, neoplasms, computed tomography, magnetic resonance imaging, tumour staging
This article reviews the MR imaging protocols, staging, and imaging features related to malignant sinonasal neoplasms, along with pearls and pitfalls.
1 paź 2023 · SUMMARY: Sinonasal and skull base tumors are a heterogeneous group of neoplasms with considerable histologic variation and overlapping imaging features. In 2022, the World Health Organization updated the head and neck tumor classification, further emphasizing the importance of molecular data and genetic alterations in sinonasal neoplasms.
4 dni temu · Differentiating malignant tumors from benign entities is another key role of imaging in sinonasal tumors—a process that relies on specific imaging features seen on CT and MRI. For instance, benign conditions typically demonstrate smooth, well-defined margins, displaced tissue planes, bone remodeling, and T2 hyperintense signal on MRI.
