Figures

FIGURE 1:
FIGURE 1:. (A) Non-contrast-enhanced head computed tomography (CT) showing multiple sub-centimeter calcified lesions scattered throughout the supratentorial region of the brain. The presence of hydrocephalus is an important indicator of subarachnoid and intraventricular neurocysticercosis. (B) CT angiography of the cerebral arteries showing numerous focal stenoses in the left middle cerebral artery (arrow). Although not pathognomonic, this finding is highly indicative of arteritis and requires further investigation.
FIGURE 2:
FIGURE 2:. High-resolution vessel wall imaging (HR-VWI; Achieva 3.0 T; Philips Healthcare, The Netherlands; RT, 600 ms; ET, 29 ms; SPAIR; reconstruction matrix, 320; field of vision, 120 mm; voxel size 0.8 × 0.8 × 0.8 mm3; blood suppression, VISTA) in (A) (T1 axial post-contrast) showing a hypointense lesion with peripheral contrast enhancement, compatible with the vesicular colloidal stage of neurocysticercosis in the left frontal lobe (white arrow); (B) (maximum intensity projection arterial sequence SENSE) showing multifocal arterial narrowing in the left middle cerebral artery (white arrowheads); (C) (axial HR-VWI without contrast) and (D) (HR-VWI post-contrast) showing wall enhancement in the middle cerebral artery (black arrows); (E) (HR-VWI) showing leptomeningeal enhancement (curved arrow); (F) (HR-VWI post-contrast) showing enhancement in the wall of the basilar artery (black arrowheads).
