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.

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.
29 sie 2024 · Many sinonasal tumor types exhibit differentiating imaging features on CT and MRI such as anatomical location, invasion of adjacent tissue, metastasis, tumor homogeneity, internal signal intensity, and contrast enhancement.
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.
12 wrz 2024 · Sinonasal neoplasms are a remarkably heterogeneous group, reflecting the numerous tissue types present in the nasal cavity and paranasal sinuses. These entities can be relatively benign (ie, respiratory epithelial adenomatoid hamartoma) or can be exceedingly aggressive (ie, NUT carcinoma).
This article reviews the MR imaging protocols, staging, and imaging features related to malignant sinonasal neoplasms, along with pearls and pitfalls.
25 lip 2023 · Ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI) are routinely used modalities for morphological evaluation and differentiation of neoplastic from inflammatory processes and benign and malignant tumors in the sinonasal region.
