Abstract:
We report a case of atretic parietal cephalocele with a persistent parietal falcine sinus and partial absence of the straight sinus. The direct puncture angiographic study demonstrated that there was a major venous channel through the parietal skull defect. From the embryological point of view, this association may provide us with possible pathoetiologic evidence of congenital sinus pericranii is one of the alternative venous drainage pathways to compensate venous outflow in the cases of intracranial developmental anomalies.

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,...
