a-g Brain magnetic resonance imaging showed a 33 x 41 x 40 mm ring-enhanced capsule in the right frontal lobe with severe perilesional edema which leads to midline shifting to the left side, and the right ventricle was metamorphose. Diffusion weighted MR of the enhanced area revealed the lesion is an abscess. h Postoperative CT scan showed regular changes of post right temporoparietal craniotomy and deficiency of the right temporoparietal bone. i Pathological manifestation of the mass (HEx 100)

Brain MRI showed a 33 mm x 41 mm x 40 mm ring-enhanced capsule in the right frontal lobe with severe perilesional edema which leads to the midline shifting to the left side, and the right ventricle was metamorphose (Fig. 1).
a-b Preoperative chest computed tomography angiography showed a group of tortuous vascular, considered as fistulous vascular abnormality on the right lower lung field. c-e Postoperative CTA: Inferior lobe of the right lung and posterior basal segmental of pulmonary artery have high density of implant. No other pulmonary arteries have filling defect

To make further diagnosis, pulmonary artery computed tomography angiography (CTA) which is a diagnostic criterion of pulmonary AVF was performed to confirm AVF (Fig. 2a, b). One month later, embolization using Amplatzer vascular plugs was performed on him (Fig. 2c-e).
