Pseudoprogression of cerebral cavernous angiomas: the importance of proper magnetic resonance imaging technique

Magnetic resonance imaging (MRI) is the method of choice to detect cerebral cavernous angiomas. Specifically tailored MRI studies are necessary to evaluate patients with cerebral cavernous angiomas. The patient described here, for whom serial MRIs performed on different scanners falsely suggested rapid disease progression, illustrates the point.
