Abstract

The Calvarial bone defects in the lambdoid suture region are a rare bone manifestation of neurofibromatosis type 1. They may be isolated or associated with an adjacent structural lesion, such as a dural ectasia or plexiform neurofibroma. The underlying pathophysiology for the development of these types of skull defects is still unclear. We present the case of a Calvarial defect in the region of the lambdoid suture in a 7-year-old boy with a medical history of neurofibromatosis type 1 who was referred for a brain scan to explore a palpable skull defect in right parieto-occipital region , noticed by his doctor.
