Introduction and Objetives.
Carcinomas of the nasal cavity and paranasal sinuses has low incidence, but may
lead to significany morbidity and disfigurement. TC and MRI plays a key role in the
evaluation of sinonasal tumours.
Methods.
We will review four areas where the MRI is useful for evaluating of sinosanal
carcinoma, analyzing the images of three patients with this disease.
Results and Discussion.
The MRI is indicated when there are a complicated inflammation or a tumor. MRI
has a high contrast resolution to analyze the tumor mass, allows better differentiation
of the interface tumor-inflammation and determine the perineural tumor spread. It
can be used in combination with CT, which provides the assessment of bone
involvement and anatomic configuration.
Conclusions.
MRI has a higher contrast resolution, allows better tumor / inflammation
differentiation and value perineural tumor spread.
