Multiple choroid plexus papillomas of the lateral ventricle distinct from villous hypertrophy

侧脑室多发脉络丛乳头状瘤

FIG. 1. Axial T1-weighted MR images revealing slightly hypointense to isointense lesions in the right atrium and left inferior horn of the lateral ventricles (upper), and Gd-DTPA–enhanced images demonstrating a marked homogeneous enhancement of the lesions (lower).

FIG. 2. Sagittal T1-weighted MR images with Gd-DTPA enhancement clearly revealing the anatomical relationship between the tumors and the surrounding structures, which marked their location more easily. Left: Sagittal images of the left side of brain. Center: Sagittal image of the center of brain. Right: Sagittal images of the right side of brain.

FIG. 3. Upper: Photomicrograph of the tumor specimen obtained during the first operation in the right ventricular region. Note the papillary growth of a single and partly stratified layer of columnar epithelium, consistent with a typical choroid plexus papilloma. Lower: Photomicrograph of the tumor specimen obtained during the second operation in the left ventricular region. The histopathological characteristics are similar to those shown in the right ventricular region. H & E, original magnification 3 200.
