Determining the feasibility of diagnosing meningiomas using static teleneuropathy images transmitted electronically.

The feasibility of using still images sent via the Internet for remote neuropathological consultation was examined. We assessed the diagnostic agreement between three groups of neuropathologists and a reference laboratory. All groups independently evaluated pictorial data exchanged by e-mail or ftp server. In the group of benign meningothelial meningioma agreement was reached in 100%, 100%, 92% of cases. In three cases of malignant meningioma agreement was achieved in 100%, 33%, 33% of cases, and in ten cases of atypical meningioma agreement was achieved in 50%, 30%, 40% of cases. Average concordance for all three groups was 83.33%, 54.33%, 57.67%. Our experiment showed that there were no discrepancies in the typical cases of benign meningothelial meningiomas. Disagreement related to the grade II and III lesions i.e. atypical and malignant meningioma. Atypical as well as malignant meningioma seems to need more direct discussion to achieve consensus. The main problem was the subjectivity of the local pathologist who overstated the informational content of the images, and an insufficient number of pictures. This may be prevented in the future by employment of dynamic teleneuropathology using a very high-resolution camera.
