Abstract
This study describes and characterizes a narrow, hollow tubular structure, termed as duct-like diverticulum (DV), found specifically at the basal midline of papillary craniopharyngiomas (PCPs) located within the third ventricle (3V). The presence of this structure was systematically investigated on autopsy studies and magnetic resonance imaging (MRI) scans of 3536 craniopharyngioma (CP) cases published in the medical literature from 1911 to 2021, as well as in other twelve 3V tumor categories (n = 1470 cases). A basal DV was observed in a total of 50 PCPs, including two of our own cases. This DV corresponds to a tubular-shaped recess invaginated at the midline bottom of the tumor, following the same angled trajectory as the pituitary stalk. It can be easily seen as a hypointense linear structure on T1- and T2-weighted MRI scans, with two main length types: long DVs (74%), which reach the tumor center, and short DVs (26%), which penetrate the tumor only a few millimeters. The DV sign identifies the papillary CP type with a specificity of 100% and a sensitivity of 33% in the overall CP population. This finding also serves to establish the strictly intra-3V location of the lesion with a 95% specificity and 42% sensitivity among papillary CPs. No similar basal DV was found in adamantinomatous CPs nor among other categories of strictly 3V tumors. Consequently, the presence of a diverticulum in a 3V tumor represents a morphological signature pathognomonic of the papillary type and a valuable sign to reliably define the strictly 3V topography.

D, E Magnetic resonance imaging (MRI) characteristics of the DV in author’s case 1 (number 49; Table 1). The DV is identified as a linear homogeneously hypointense structure which follows a diagonal trajectory along the tumor midline on the T1-weighted MRI scans after gadolinium administration. It is open to the suprasellar cistern and preserves the same signal as the cerebrospinal fluid (black arrows). F Another example of a duct-like basal diverticulum in a solid 3V CP of the squamous-papillary type (author’s case 2, number 50 in Table 1). In this case, the DV ends in a non-bifurcated manner (yellow arrow) as a “cul-de-sac” at the center of the tumor
