Kidney with Polycystic Disease Polycystic kidney disease is a genetic condition where many cysts form in the kidneys, causing them to enlarge and lose function. In the photo, you can see a comparison of a polycystic kidney to a football — this clearly shows how the disease can change the organ's shape and size. It's important to remember that polycystic kidney disease can lead to serious complications like high blood pressure and kidney failure.

"Lion face" is a specific form of hyperostosis that affects the bones of the skull (craniosclerosis). The skull bones, especially in the facial area, grow excessively, gradually compressing and filling all natural cavities and openings. As a result, the face widens and flattens in the middle due to the overgrown upper jaws, giving it some resemblance to a lion's snout.

At 20 weeks pregnant, she "saw" her baby with her hands. For the blind mom, an ultrasound image was turned into a 3D model — a tactile portrait of the baby that she could feel with her fingers. Next to it was a Braille inscription: "I am your son." Sometimes technology isn’t about gadgets. It’s about the chance to feel something that was previously out of reach.

False hip joint The development of this condition is associated with a disruption of the normal bone healing process after a fracture. This often happens after gunshot wounds or open injuries. In half of all cases, it leads to persistent and severe disability.

Teeth of the brain. A four-month-old baby had a brain tumor removed in which numerous fully formed teeth were found. The benign growth – a craniopharyngioma – develops from embryonic cells.
