We describe the use of a combination of fat-suppression SPIR (spectral inversion recovery) and subtraction FLAIR imaging to aid in detection of abnormal meningeal enhancement.
BACKGROUND: Computerized digital presentations have become standard in most medical schools without research proving their effectiveness. PURPOSE: The purpose was to determine if differences in (a) subjective evaluation; (b) short-term retention of material; and (c) long-term retention of material occurred with the use of static overheads versus computerized, animated PowerPoint for a presentation to medical students. METHODS: All students rotating on a required clerkship attended a standard lecture presented by 1 faculty member. The content of the presentation remained the same, but the instructional media varied (overheads on even months, animated PowerPoint on odd months). Students completed a posttest and subjective evaluation immediately following the lecture and repeated the posttest 1 year later. Unpaired t tests were used to compare the 2 groups. RESULTS: There were no significant differences between the groups on any parameter. CONCLUSIONS: In this study, students rated both types of presentation equally and displayed no differences in short- or long-term retention of material.
Transalar encephaloceles are rare lesions that do not fit the standard classification of basal encephaloceles. Typically, these lesions present in adulthood, with nonspecific symptoms. We report here a case of a patient with Wegener disease in whom a large transalar encephalocele posterior to the sinus was noted when he was preoperative for left maxillary sinus surgery. The encephalocele demonstrated irregular peripheral enhancement along the margin--a very uncommon finding--as well as contrast enhancement of the basal meninges, which can be seen occasionally with Wegener granulomatosis.
