Abstract
PURPOSE: To determine changes in tectal tumors through initial and follow-up MRI, and clinical outcome. MATERIALS AND METHODS: Fifteen patients with tectal tumor were involved in this study, Singnal intensity,enhancement pattern, and invasion of adjacent structures were evaluated on initial MRI, and tectal contour,enhancement pattern and extension to another structures, on follow-up MRI, which averaged 14 mths and involvedmine patients. The period of clinical stability was assessed on the basis of medical records. RESULTS: In allcases, initial T2 WI images showed high signal intensity, though on T1 WI, SI was variable. Contrast enhancementwas observed in seven cases(diffuse, n=3, ring-like, n=3, focal, n=1), and invasion of adjacent structures wasidentified in four(tegmentum of thalamus). On follow-up MRI, changes in tectal contour and enhancement patternwere observed only in patients, who underwent CSF diversion(n=7). the average period of clinical stability was3.6(range, 0.3-12) years. All patients survied. CONCLUSION: Follow-up MRI showed tectal tumors progressed onlyslowly and the clinical outcome was favorable.
