YOU BE THE PATHOLOGIST!
What is this histologic staining and which structure with a labyrinthic shape does it highlight?
Hematoxylin-eosin-saffron staining in the rete mirabile!
Hematoxylin-eosin-saffron (HE&S) staining was used to stain this histological section of the brain. This image shows the rete mirabile which translates to “wonderful net” in Latin, and it refers to a remarkable network of blood vessels located at the base of the brain. HE&S staining allows collagen fibers (in bright orange) to be distinguished from surrounding tissues with high contrast in a large variety of tissue samples.
While commonly found in sheep and pigs, the rete mirabile is an extremely rare occurrence in humans. This intricate vascular structure surrounds the pituitary gland and holds great potential for innovators working on neurovascular interventions, particularly during the preclinical stage when guidewires need to be challenged.
