“…Our results of an overall frequency of 21.8 % for incidental mastoid T2-hyperintensity are similar to those obtained by previous studies [7,8,15]. The frequency of pronounced (≥50 %) mastoid opacification was much lower in our data, at only 4.8 %.…”

“…Correlations between mastoid T2-hyperintensity and clinical history or signs of otitis media are controversial; stronger associations to clinically relevant disease have been reported in adults [7][8][9]15]. Intramastoid bright signal on T2-WI has been shown to be a source of AM misdiagnosis by radiologists, potentially leading to unnecessary investigations or treatment [10,11].…”

“…Unfortunately, this is also a fairly common incidental finding in head MRI scans [7][8][9]. Intramastoid T2 hyperintensity alone is unreliable for making the diagnosis of mastoiditis because it yields many wrong positive diagnoses in radiological imaging, which have lead to unnecessary consultations and treatments [10,11].…”

“…When the middle ear shows slight hypointensity, isointensity or slight hyperintensity on T1WI or hyperintensity on T2WI, it is considered abnormal [11]. The abnormalities of otic barotrauma on MRI can be divided into 3 types according to their sectional anatomic site: (1) middle ear cavity and mastoid cavity; (2) middle ear cavity alone; (3) mastoid cavity alone[9]–[11], [21]–[23]. The severity of otic barotrauma on MRI was graded according to the number of anatomic sites involved.…”

Background and PurposeTo study the MRI findings of otic and sinus barotrauma in patients with carbon monoxide(CO) poisoning during hyperbaric oxygen (HBO) therapy and examine the discrepancies of otic and sinus abnormalities on MRI between barotrauma and acute otitis media with effusion.Materials and MethodsEighty patients with CO-poisoning diagnosed with otic and sinus barotrauma after HBO therapy were recruited. Brain MRI was performed to predict delayed encephalopathy. Over the same period, 88 patients with acute otitis media with effusion on MRI served as control. The abnormalities of the middle ear and paranasal sinuses on MRI were noted and were compared between groups. Nine patients with barotrauma were followed up by MRI.ResultsIn the barotrauma group, 92.5% of patients had bilateral middle ear abnormalities on MRI, and 60% of patients had both middle ear cavity and mastoid cavity abnormalities on MRI in both ears. Both rates were higher than those in the control group (p = 0.000). In the two groups, most abnormalities on MRI were observed in the mastoid cavity. The rate of sinus abnormalities of barotrauma was 66.3%, which was higher than the 50% in the control group (p = 0.033). In the nine patients with barotrauma followed up by MRI, the otic barotrauma and sinus abnormalities had worsened in 2 patients and 5 patients, respectively.ConclusionMRI is able to depict the abnormalities of otic and sinus barotrauma in patients with CO-poisoning during HBO therapy and to differentiate these from acute otitis media with effusion.
