From: Intracerebral atypical calcification in nongalenic pial arteriovenous fistula: a case report
Noncontrast computed tomography showing a huge calcified egg-shaped mass. With a small adjacent calcified lesion (A) and a new episode of hemorrhage (B). CT-Angiography of the lesion (C). T1-weighted parasagittal (D) and T2-weighted coronal (E) magnetic resonance images reveal large mass lesion with signal void rim indicative of calcification and central hypersignal intensity due to met-hemoglobin deposition. Post-operative brain CT scan (F).
