Magnetic Resonance Imaging and Computed Tomographic Findings After Temporal Lobe Injury

Arch Otolaryngol Head Neck Surg. 2001;127(3):339. doi:10.1001/archotol.127.3.339

We read with great interest the article by Jones et al1 entitled "Temporal Lobe Injury in Temporal Bone Fractures," which appeared in the February 2000 issue of the ARCHIVES. Although there are some terminological and methodological parts that need reevaluation, the article generally contains some new and significant findings.

Table 2 states that no temporal bone fractures were found on magnetic resonance imaging (MRI) scans. However, Table 1 states there was a right longitudinal temporal bone fracture in patient 1 that was detected by MRI. The term enhancement means pathological opacification after contrast administration on computed tomographic (CT) or MRI imaging scans. In the "Patients and Methods" section, the authors stated that "all patients were evaluated using non–contrast-enhanced CT scans. . . ." But the terms ipsilateral meningeal enhancement, contralateral meningeal enhancement, and labyrinthine enhancement were used in Table 2. However, no contrast was given on CT examination, whereas contrast was administered on MRI examination. Jones and colleagues compared the results of the non–contrast-enhanced CT scans and the contrast-enhanced MRI scans. We believe that it would have been better to compare the results of contrast-enhanced CT scans with those of contrast-enhanced MRI scans or to report the results only of the MRI scans.
