Sinus pericranii

Sinus pericranii (pronunciation: /ˈsaɪnəs pɛrɪˈkreɪniaɪ/) is a rare anatomical variant of the dural venous sinuses of the brain. The term is derived from the Latin words 'sinus', meaning 'cavity' or 'channel', and 'pericranii', meaning 'around the skull'.

Definition

Sinus pericranii is an abnormal connection between the intracranial dural sinuses and the epicranial veins. It is characterized by a scalp swelling that communicates with the intracranial dural sinuses. The swelling typically increases in size with straining or the Valsalva maneuver and decreases when the patient is in the upright position.

Symptoms

The most common symptom of sinus pericranii is a soft, compressible scalp swelling. Other symptoms may include headache, nausea, vomiting, and visual disturbances. However, many patients with sinus pericranii are asymptomatic.

Diagnosis

Diagnosis of sinus pericranii is typically made using imaging studies such as computed tomography (CT) or magnetic resonance imaging (MRI). These imaging studies can show the abnormal connection between the intracranial dural sinuses and the epicranial veins.

Treatment

Treatment of sinus pericranii is usually conservative, as many patients are asymptomatic. In cases where the sinus pericranii is causing symptoms, surgical treatment may be considered.
