Sinus Pericranii is a rare medical condition characterized by an abnormal connection between the intracranial venous system and the extracranial veins on the surface of the skull. The word is pronounced /ˈsaɪnəs/ /ˌpɛrɪˈkreɪni/ in IPA phonetic transcription. The first part of the term 'sinus' is pronounced as 'SIE-nuhs', while 'pericranii' is pronounced as 'per-ih-KRAY-nee'. The pronunciation highlights the need for proper spelling to communicate effectively in technical and medical fields where accurate communication is crucial.
Sinus pericranii is a medical condition characterized by an abnormal communication between the veins of the scalp and the veins on the surface of the brain. It is a rare congenital disorder that occurs from birth, although symptoms may not present until later in life. Sinus pericranii is considered a type of cranial arteriovenous fistula (AVF).
The condition is characterized by the presence of a large, soft, pulsatile mass on the scalp, typically located along the midline, above the nape of the neck, or over the forehead. This mass is caused by the abnormal connection between the veins of the scalp and the dural sinuses within the skull. The veins become dilated due to increased blood flow, resulting in the visible and palpable mass.
Sinus pericranii is usually asymptomatic and does not pose a significant health risk. However, it may cause certain complications, such as cosmetic concerns, recurrent bleeding, or thrombosis. In some cases, the condition may be associated with other congenital anomalies or underlying medical disorders.
Diagnosis of sinus pericranii involves a thorough physical examination, medical history review, and imaging tests like magnetic resonance imaging (MRI) or computed tomography (CT) scan. Treatment options depend on the specific symptoms, age of the patient, and associated complications. Surgical intervention may be considered in some cases to divert the blood flow or to remove the abnormal connection between the veins.
Overall, sinus pericranii is a relatively uncommon condition that requires medical evaluation and management by healthcare professionals experienced in vascular anomalies.
The word "sinus pericranii" is derived from Latin and Greek roots.
"Sinus" comes from the Latin word "sinus", which means "curve", "bay", or "hollow". In medical terminology, it is often used to refer to a cavity or channel within the body.
"Pericranii" is a combination of the Latin word "peri", meaning "near" or "around", and the Greek word "kranion", which means "skull".
Therefore, "sinus pericranii" literally translates to "cavity near the skull". In medical context, it refers to a rare congenital condition characterized by an abnormal communication between the veins inside the skull and the veins on the scalp.
