“…Mucosal thickening may be present in a wide range of distinct cases, such as acute and chronic rhinosinusitis, from diverse pathogenic nature (fungi, virus, allergic) [ 17 ]. Although there is no consensus in literature [ 7 , 22 , 23 ], mucosal thickening up to 2 mm is considered normal [ 7 ]. However, mucosal thickening can also be present as an asymptomatic imaging finding [ 17 ], as exhibited in the current case reported.…”

“…Studies considering DWI in paranasal sinus diseases available in literature focused essentially on ADC comparisons between groups of malignant neoplasms and benign lesions, considering a wide variety of inflammatory lesions in the group of benign lesions [ 20 , 21 , 31-37 ]. Inflammatory diseases exclusively were investigated by two studies [ 22 , 38 ] with distinct objectives and methodology.…”

“…Kilickesmez et al [ 22 ] explored the relationship between mucosal thickening T1-weighted, T2-weighted signals and ADC values with patient symptomatology, measured by three different quality life questionnaires. In this study, investigators described a mean ADC value of 2.23 × 10 -3 mm 2 /s, which is higher than the present report mucosal thickening ADC mean value, which was 1.83 × 10 -3 mm 2 /s.…”

BackgroundMagnetic resonance imaging is considered a preferable imaging examination in the diagnosis of inflammatory maxillary sinus disease and can provide precise sinonasal characterization. Diffusion-weighted magnetic resonance imaging and apparent diffusion coefficient are complementary magnetic resonance imaging tools that can be applied to the differentiation of sinus diseases. In this report, 3 cases of inflammatory maxillary sinus diseases imaging findings considering diffusion-weighted magnetic resonance imaging features were described. Additionally, a literature review considering the use of diffusion-weighted magnetic resonance imaging in inflammatory lesions is provided.MethodsThe cases reported were: presence of air-fluid levels, mucosal thickening and a mucous retention cyst. Conventional magnetic resonance imaging and apparent diffusion coefficient (ADC) maps, with ADC values were demonstrated. In the literature review, the studies considering inflammatory lesions were detailed, as well as ADC values established by investigators.ResultsADC values for presence of air-fluid levels, mucosal thickening and mucous retention cyst were respectively: 1.99 x 10-3 mm2/s; 1.83 x 10-3 mm2/s; 2.05 x 10-3 mm2/s.ConclusionsIt was observed that apparent diffusion coefficient values from the inflammatory lesions described in this report were different and apparent diffusion coefficient may be useful in the differentiation of these maxillary sinus alterations. Further larger sample investigations considering apparent diffusion coefficient values focusing in inflammatory lesions are recommended. The lack of studies considering the use of diffusion-weighted magnetic resonance imaging on inflammatory diseases diagnostic was the major limitation to the literature review.

“…There has also been previous study on the impact of rhinosinusitis of odontogenic or nonodontogenic origin, 31 and prior reports have assessed SNOT-22 in parallel to incidental findings; however, these studies have not focused on whether clearly accounting for incidental findings could alter any observed associations, to inform optimization of future scoring mechanisms. 29…”

Objective The overall discriminatory ability of validated instrument scores for computed tomography (CT) findings of chronic rhinosinusitis has limitations and may be modified by multiple factors. To support optimal methods for assessment, we studied which factors could influence this relationship, including the concurrent impact of multiple discrete CT scoring mechanisms, colocalized imaging findings, and nasal comorbid conditions. Study Design Observational outcomes study. Setting Academic medical center. Methods Patients with sinonasal complaints who completed the 22-item Sinonasal Outcome Test (SNOT-22) and underwent CT were included. Multivariate ordinal regression was utilized to assess associations. CT data were quantified with the Lund-Mackay system, Zinreich system, and a direct measure of maximal mucosal thickness. The impact of incidental findings (mucous retention cysts, periapical dental disease) and nasal comorbid conditions was also assessed. Results A total of 233 patients were included. SNOT-22 nasal scores were significantly associated with CT results when those with incidental findings were excluded, regardless of the radiologic scoring mechanism utilized: Lund-Mackay regression coefficient, 0.321 ( P = .046); Zinreich, 0.340 ( P = .033); and maximum mucosal thickness, 0.316 ( P = .040). This relationship subsided when incidental findings were present. SNOT-22 overall scores, sleep scores, and psychological domain scores had no significant association with imaging results, regardless of radiologic scoring system utilized. Nasal comorbid conditions had inconsistent associations. Conclusions SNOT-22 nasal domain scores were associated with all 3 radiologic scoring systems when incidental findings were absent but not when they were present. Delineating the presence or absence of these colocalized findings affected the relationship between SNOT-22 scores and radiological results, beyond other concurrent factors.

“…Na literatura, não há concordância sobre o valor numérico exato deste espessamento que indicaria ausência de processos patológicos sinusais. Postula-se que um espessamento de até 2 mm verificados em TC ou RM é indicativo de ausência de sinusopatia 61 .…”
