Comments:
MRI scan (with contrast) of a meningioma that was discovered incidentally (see history in the previous image). MRI is the radiographic investigation of choice for accurate diagnosis and characterization of meningiomas and most other intracranial lesions. With contrast, most meningiomas are intense and show homogenous enhancement as seen here. This case illustrates how large some meningiomas can grow if located in the so-called silent areas of the brain such as frontal and temporal lobes. Despite the irregular outline of the tumor, it had typical histologic features with numerous psammoma bodies and no evidence of brain invasion. Case reproduced with permission, courtesy of Dr. Frank Gaillard; Radiopaedia; Complete case is here.
