Axial (a-c) unenhanced and (d-f) enhanced cerebral computed tomography images showing multiple, diffuse hyperdense lesions in the infratentorial (pons), basal ganglia, and other supratentorial regions of the brain (red arrows) suggesting multiple cerebral cavernomas.

The findings (Figure 1) were misdiagnosed as cerebral metastases.
Axial brain MRI: (a-c) T1W, (d-f) T2W, and (g-i) T1W postgadolinium enhanced images showing multiple diffuse cerebellar, pons, bilateral basal ganglia, and cerebral lesions of varying sizes (red arrows); the larger lesions on T1W and T2W images showed hyperintense core and peripheral rim of hypointensity due to hemosiderin in keeping with multiple cerebral cavernomas. No enhancement was noted postgadolinium contrast administration (g-i).

No other associated abnormalities like arteriovenous malformations, aneurysms, or capillary telangiectasia were visualized (Figures 2 and 3).
Axial brain MRI: (a-c) GRE/T2* and (d-f) SWI showing multiple diffuse cerebellar, pons, midbrain, bilateral basal ganglia, and cerebral lesions of varying sizes (red arrows) which became more prominent due to susceptibility artefacts (blooming) in keeping with multiple cerebral cavernomas.
