case_images: Computed tomography (CT) scan of brain revealed mild asymmetrical dilatation of left ventricle with normal size right lateral, third and fourth ventricles without periventricular edematous changes suggesting possibility of outlet obstruction of lateral ventricle [Figure 1a]. No significant postcontrast enhancement noted within the lesion [Figure 1b].
case_images: (a) Intraoperative ultrasonography is showing a hypoechoic cystic lesion in left lateral ventricle with another small cystic lesion within this lesion. (b) Hydatid cyst after excision

case_images: Intraoperative USG of the cystic mass showed a hypoechoic cystic lesion in the left lateral ventricle with another small cystic lesion within this hypoechoic lesion [Figure 2a]. The cystic mass was removed successfully by gentle irrigation of the cleavage plane between the cyst wall and the brain interface with saline [Figure 2b].
case_images: (a) Microphotograph (H and E, x40) showing ectocyst (laminated wall) of hydatid cyst. (b) Microphotograph (H and E, x40) showing ectocyst (laminated wall), scolex containing multiple hooklets with mixed inflammatory infiltrate
