Abstract:
'Sinus pericranii' is an abnormal communication between the extracranial veins and the dural venous sinuses (usually the superior sagittal and the transverse sinuses). It is a rare childhood abnormality. We report a case of a 6-month-old boy presenting with a scalp swelling in the left parietal region. Ultrasound with color Doppler and MRI showed a dilated epicranial vein that communicated with the superior sagittal sinus. This anomalous venous connection is known as sinus pericranii. We describe the imaging findings, associated abnormalities and management of this rare vascular abnormality.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
