A 3 cm AVM was discovered in the right posterior frontal lobe, just anterior to the central sulcus (Figure 1).
Bone windows of CT of the head after first embolization, showing high attenuation embolic material (Onyx) in the nidus of the AVM (a) as well as extension through the draining vein and a thin strand in the superior sagittal sinus.

The postprocedure CT scan revealed a small amount of subarachnoid hemorrhage in the right sylvian fissure adjacent to the AVM, embolization material within the AVM, and a small tail of Onyx extending through the draining vein into the superior sagittal sinus (Figure 2).
AP chest X-ray and accompanying select axial CT slice from the day of respiratory deterioration. The typical "ground glass" appearance and consolidation is noted.

The CT imaging demonstrated perihilar and bibasilar ground glass opacities and bibasilar interlobar septal thickening with Kerley B-lines, all consistent with pulmonary edema (Figure 3).
