A Rare Existence of Significant Number of Wormian Bones in the Lambdoid Suture

Wormian bones may be defined as those accidental or intercalated bones of the cranium having no regular relation to their ossifying centres. They are associated with cranial and central nervous system abnormalities. The present case showed the presence of significant number of wormian bones (SNWB) 34 nos.11 on the left, 5 in and around lambda and 18 on the right in an adult dry Indian skull. It also showed other significant features like denticulogenesis imperfecta and exaggerated occiput, predicting it to be a case of Osteogenesis imperfecta Knowledge of these variations (SNWB) is very important for anthropologists, forensic experts, radiologists, orthopedic and neurosurgeons to avoid misleading for multiple fractures of the skull.
