Sinus pericranii: an uncommon tortuous vascular anomaly with traumatic origin

ABSTRACT

Sinus pericranii is an unusual venous anomaly characterized by communication of pericranial varicosities with an underlying dural sinus. The varicosities are intimately associated with the periostium, are distensible, and vary in size with changes in intracranial pressure. Symptoms are infrequent but include headache, vertigo, feelings of fullness, local pain, or dermatological lesion. It presents at the paediatric age group more than other age groups and it affects males more than females. Although its aetiology has not been settled yet, however, computerized tomography scan discloses those of traumatic nature. Although, in many instances, it raises a cosmetic concern to the patient and parents, the condition is not without possible "significant' complications, e.g., haemorrhage, infection, dermatological, and air embolism during operative intervention. We describe the clinical features, imaging and operative findings of a case of Sinus pericranii presented to our department, the reason for the surgical treatment of which was the cosmetic concern of the patient's parents
