Digital data and the 19th century teratology collection

Area of Science:

• Historical teratology and congenital anomalies research.

Background:

• The Vrolik collection, amassed by Gerardus and Willem Vrolik, represents a significant historical resource in the study of congenital anomalies.
• Willem Vrolik extensively documented teratological specimens in his 1844 Handbook of Pathological Anatomy and 1849 atlas.

Discussion:

• Re-cataloguing the Vrolik collection (1991-1994) applied modern syndromological perspectives to historical teratological specimens.
• Advanced imaging techniques, including MRI and CT scans, were vital for diagnosing rare syndromes and malformations within the collection.

Key Insights:

• Diagnosis of rare syndromes, skeletal dysplasias, neural tube defects, and conjoined/acardiac twins within the Vrolik collection.
• Identification of unique cases with limited prior reporting, offering insights into malformation relationships.
• Certain specimens provide crucial 'missing links' in understanding teratological series and developmental abnormalities.

Outlook:

• Continued study of the Vrolik collection can illuminate historical and contemporary understanding of congenital anomalies.
• The integration of historical collections with modern diagnostic tools enhances our knowledge of developmental biology and pathology.
