(A) Noncontrast head CT showing acute right cerebellar ICH with smaller adjacent focus of hemorrhage (black arrow).
(B) Subsequent FLAIR sequence on brain MRI after decompressive craniectomy showing flow void (white arrow) adjacent to ICH (white dashed arrow).
(C) Digital subtraction angiogram subsequently identified an AVM with a nidus (white arrowhead), feeding artery (white thick arrow), and draining vein (white short arrow).
