Wimberger's ring sign

Wimberger's ring sign is a medical sign observed in radiology, specifically in pediatric radiology. It is named after the German radiologist, Paul Wimberger, who first described the sign in 1979.

Definition[edit | edit source]

Wimberger's ring sign is a radiological sign that is characterized by a ring of increased density around the epiphysis of long bones. This sign is typically observed in X-ray images and is indicative of congenital syphilis in infants and young children.

Clinical Significance[edit | edit source]

The presence of Wimberger's ring sign is a strong indicator of congenital syphilis, a disease caused by the bacterium Treponema pallidum. This condition is transmitted from an infected mother to her fetus during pregnancy. The sign is particularly significant as early detection and treatment of congenital syphilis can prevent serious complications such as blindness, deafness, and mental disability.

Diagnosis[edit | edit source]

The diagnosis of Wimberger's ring sign is made through radiological examination, typically using X-ray imaging. The sign is characterized by a ring of increased density around the epiphysis of long bones, such as the femur or humerus. This is due to the periostitis and osteochondritis caused by the Treponema pallidum bacterium.

Treatment[edit | edit source]

The treatment for congenital syphilis, the condition indicated by Wimberger's ring sign, involves the administration of penicillin. Early detection and treatment are crucial to prevent the progression of the disease and the onset of severe complications.
