CT of the head, plain and post contrast – The left frontal sinuse is partially filled with a well delineated soft tissue opaque structure which is located on the floor of the frontal sinus and ectends into the dorsal nasal concha. Mild pressure related atrophy of the neighboring bonylamina is seen. There is no evidence of turbinate destruction or aggressive osteolysis associated with this structure
The polypoid hyperplasia is likely of low clinical significance at this point. The underlying cause of polyp formation usually is chronic inflammation. Currently there is no computed tomographic evidence of rhinitis.
There are no abnormal findings associated with the brain. However this does not rule out inflammatory, metabolic/toxic, degenerative or other brain disease entirely. The imaging study should be complemented by a CSF examination at the least. In case this is inconclusive or the patient is refractory to therapy and MRI may be considered as well.
