Is Non-Contrast Enhanced CT of Paranasal Sinus Adequate for the Diagnosis of Complicated Sinusitis?
Keywords:
CT paranasal sinus; complicated sinusitisAbstract
Objective: To evaluate the accuracy of NECT compared with CECT of PNS for the detection of complicated sinusitis.
Methods: A retrospective review of 96 patients (mean age, 51.78; range 20-84 years), including 44 men and 52 women, with clinically suspicious complicated sinusitis who underwent both NECT and CECT of PNS. Analysis and comparison between CT PNS on NECT and CECT for detection of complicated sinusitis were performed.
Results: Complicated sinusitis was detected in 7 out of 96 patients. Orbital complications alone in 5 patients and 2 patients with both orbital and intracranial complications were found. Detection of orbital complication on NECT was 5 out of 7 patients, giving a sensitivity of 71.4% and specificity of 100%. Detection of orbital complication on CECT was 6 out of 7 patients, giving a sensitivity of 85.7% and specificity of 100%. In this presented study NECT could not demonstrate intracranial complication such as cavernous sinus invasion and brain parenchymal lesion.
Conclusion: NECT of PNS shows high accuracy for the diagnosis of orbital complication, but low sensitivity for the detection of intracranial complication.
