A 71‐year‐old female with an intrasellar mass

This is the authors' abstract. We don't add key points for this paper.

Magnetic resonance imaging revealed an intrasellar and suprasellar tumor with significant homogeneous contrast enchancement (Figure A). Under microscopy showed the dilated cavernous spaces of irregular size and shape, which are embedded in the loose collagenous matrix and adipose tissue, lined by normal flattened endothelial cells. These spaces are mostly empty and some cavities are filled with proteinaceous material (Figure B). This mass is immunohistoreactive for CD34 (Figure C) and D2-40 (Figure D).
