Summary
Sinus pericranii is a rare scalp condition where a blood-filled nodule connects to a dural sinus. Early diagnosis is crucial due to potentially lethal complications.
Area of Science:
- Dermatology
- Neurosurgery
- Radiology
Background:
- Sinus pericranii is a rare vascular malformation involving the scalp and intracranial dural sinuses.
- It presents as a congenital or acquired epicranial nodule filled with blood.
Observation:
- Two pediatric cases are presented: one congenital, one post-traumatic.
- Clinical presentation and dermatologic manifestations are variable and often mimic other scalp disorders.
Findings:
- Diagnosis can be challenging due to variable clinical presentation.
- Communication with intracranial dural sinuses via dilated diploic veins is a key diagnostic feature.
Implications:
- High index of suspicion is warranted due to risks of hemorrhage, infection, and air embolism.
- Dermatologists and dermatopathologists play a role in identifying potential cases through scalp and forehead skin changes.
