Each paranasal sinus was examined separately (the left and the right frontal, anterior ethmoidal, maxillary, posterior ethmoidal, and sphenoid sinuses) on the sections obtained in all three orthogonal planes (Figure 1).The sinusal lesions were classified as follows:
pylori was detected in the ethmoidal mucosa in 4 of 12 patients with CRS, but it was not detected in 13 CRS-free patients with the concha bullosa.
There was evidence of sinusitis in the maxillary sinus for all the patients while 2 patients had isolated sphenoid sinusitis and another 2 children had frontal and ethmoidal sinusitis at the same time.
Imaging, which included CT brain, MRI brain, and CT sinuses, demonstrated hyperdense soft-tissue opacification of the right frontal, sphenoid sinuses, and ethmoidal air cells with corresponding decreased T2 signal and osseous erosive changes involving medial orbital wall with soft tissue extending to the orbital apex.
On contrast-enhanced MRI, the enhancement was confined from ethmoidal sinus to the bottom of frontal lobe, which suggests the empyema stems from sinus and flows along the space of interhemispheric and infratentorial subdural.
The initial diagnosis of nasal polyposis was based on two criteria: (1) the visualization of bilateral polyps in the nasal cavities on endoscopic examination, and (2) the existence of bilateral ethmoidal opaque areas on multislice computed tomography (CT) with a 1.25-mm slice thickness (120 Kv, 20 mA), located either in the anterior or the posterior ethmoid sinuses.
An experience of steroid in recurrent ethmoidal nasal polyps at tertiary care hospital.
In the present study, maxillary sinus was predominantly involved (86%) followed by Ethmoidal sinus (72%), Sphenoid sinus (38%) and Frontal (34%).
Imaging (CT scan) of para nasal sinuses (PNS) showed left maxillary, ethmoidal and frontal sinusitis (Figure 1).
We found haziness in maxillary sinus followed by frontal and ethmoidal sinus as the most common pathology (Table 2).
