Developmental venous anomalies and cerebral cavernous malformations: Partners in crime

Figure 4 Cerebral cavernous malformation. A: Computed tomography scan performed in a 65-year-old woman due to memory deficits displayed a mildly hyperdense lesion in the right parietal lobe (dashed circle), which raised suspicion for a hemorrhage; B and C: On the subsequent magnetic resonance imaging examination performed, the lesion (dashed circle) was hypointense on T1-weighted images (B), without significant or discernible contrast enhancement following intravenous gadolinium administration (C); D: On T2-weighted images, the lesion (dashed circle) displays a heterogeneously hyperintense center with a low signal periphery (arrows) compatible with a hemosiderin rim; E: Susceptibility-weighted imaging shows intense blooming of the lesion (dashed circle). The findings were consistent with a cerebral cavernous malformation diagnosis.
