case_images: Brain magnetic resonance imaging of case 1. A 4x3-cm ring-enhanced mass in the right frontal lobe, which was associated with severe edema and midline shifting to the left side (A). Diffusion restriction of the enhancing area suggests that the lesion is an abscess (B).

case_images: Brain magnetic resonance (MR) imaging revealed a 4x3-cm ring enhanced mass in the right frontal lobe, which was associated with severe edema and midline shifting to the left side (Fig. 1).
case_images: Chest computed tomography (A) and angiography (B) of case 1. Fistulous vascular abnormality on the left lower lung field (A). A catheter is used to perform embolization (white arrow). Another lesion on the left upper lung field was already embolized with coils (black arrow; B).

case_images: A 45-year-old woman (case 2) presented with a 7-day history of a progressive left hemiparesis. Enhanced brain magnetic resonance (MR) imaging shows a well-enhancing ovoid mass on the right motor and sensory cortex measuring 1.5x0.9 cm (A). Diffusion weighted MR reveals restriction of the mass (B).

case_images: MR imaging showed a diffusion-restricted ovoid mass on the right motor and sensory cortex measuring 1.5x0.9 cm that was surrounded by diffuse vasogenic perilesional edema (Fig. 3). MR imaging and MR spectroscopy revealed an enhancing lesion involving the right motor and sensory cortex and increased lactate/lipid complex, which was compatible with a brain abscess.
case_images: Chest computed tomography (A) and angiography (B) of case 2. Fistulous dilatation of the pulmonary vasculature on the right upper lung field (A). The lesion is approached with a catheter to perform embolization. It was a single lesion (B).
