Abstract
Background
Growing skull fracture or leptomeningeal cyst is an uncommon occurrence after severe head trauma in childhood. It is mostly observed in infants and children less than 3 years of age. Another uncommon complication of head trauma is development of porencephalic cyst.
Case presentation
We present an unusual case of post-traumatic type III leptomeningeal cyst in a 9-month-old infant with history of head trauma 3 months ago. CT and MR imaging revealed widening of bony defect compared to previous imaging, and herniation of porencephalic cyst through the defect, leading to formation of a large cystic swelling in scalp. The 3 month delay in evaluation of the scalp swelling was due to lack of patient education after trauma, and no subsequent follow-up.
Conclusions
Knowledge about etiopathogenesis and risk factors of leptomeningeal cyst development after head trauma ensures that close follow-up is done in such cases for early detection and management of growing skull fracture.
