Multiple Cavernomas in Brain

CT findings of Cavernomas or Cavernous Angiomas of Brain

NECT

Negative in 30-50%
Well-delineated round/ovoid hyperdense lesion, usually < 3 cm
40-60% Ca++
No mass effect unless recent hemorrhage
Surrounding brain usually appears normal

CECT: 

Little/no enhancement unless mixed with other lesion (e.g., DVA)

CTA: Usually negative

Multiple Cavernomas in Brain

Young male patient with recurrent brain hemorrhages, due to multiple Cavernomas.

Cavum Septum Pellucidum

Cavum Vergae

The main lesion - which is heterogenously hyperdense. Lesion also showed CSF density areas - possibly sequelae to old hemorrhages. Characteristic MRI appearance is described in T2WI as 'Popcorn Appearance'.

Tiny lesion in right high frontal lobe.

This patient had previously undergone MRI Brain, which showed multiple cavernomas (SWI blooming) - much more than that in present CT.
