Abstract
- Magnetic Resonance (MR) imaging features of pineal region tumors were analyzed in 14 oncologic cases. The tumors were classified as germ-cell tumors, glial tumors, pineal parenchymal tumors, meningiomas, and cysts. They demonstrated different MR signal characteristics on precontrast scans and nodular or ring type enhancement with occasional central lucencies, except for benign cysts, which have not shown enhancement. MR images were useful in defining the relationship of the tumor to the posterior third ventricle, sylvian aqueduct, vein of Galen, and tentorium. Although CT can demonstrate in more evident fashion displacement of the original pineal calcification as well as tumor calcifications, MR imaging demonstrates different signal characteristics in germinomas and pineoblastomas which can be a useful adjunct in the evaluation and differential diagnosis of these tumors.
