Concordancia radio-histológica en meningiomas intracraneales
2018
meningiomas account for 15-20% Central Nervous System primary neoplasms in adults. Many are benign, but
the 5% of them are malignant. MRI characterizes them, describing a series of radiological findings suggestive of aggressiveness,
although the diagnosis is confirmed by histopathology. Objectives: Determine if the aggressiveness of intracranial meningiomas
using MRI is consistent with histopathology. Material and Methodology: 14 cases of meningiomas with MR imaging and histopathology ranging 2004 to 2016 were reported. Its radiological characteristics were analyzed by determining their aggressiveness by MRI
and Histopathology, carried out a study of diagnostic tests. Results: 7 (50%) of the 14 meningiomas were aggressive in the study by
MRI, while 4 (28.6%) did so by histopathology. The sensibility of MRI was 100% and specificity 70%. The only variables that achieved p<0.05 by studying aggression MRI were irregular borders and heterogeneous enhancement. Conclusions: MRI is suitable for
use as initial screening in the diagnosis of intracranial meningiomas aggressiveness, being restricted for confirmatory diagnosis. We
found no significant evidence to determine what radiological characteristics define tumor aggressiveness.
