The Bluish Sign
IGS-Rainbow View is More Helpful than Grayscale View in Differentiating Mycotic Disease in Sinus Cases
Case #1 AMR is a 32-year-old woman who presented with chronic cough and a thick postnasal drip associated with a sensation of fullness in the mid faceof the left side. A nasal endoscopy revealed a severe left infundibulum disease, a bulged posterior fontanelle and a thick brownish purulent material draining from this area. The CT demonstrated an opacified left maxillary sinus. Any other CT abnormality could not be identified using a 300 mAs window in an effort to identify a possible mycotic content in the maxillary sinus.
