Abstract:
With a distinctive shape and surrounding anatomical structures, the fourth ventricle is located in the posterior cranial fossa. There are various pathologies, either developmental or acquired, that can present as a characteristic deformity of the fourth ventricle. Therefore, this paper will cover the anatomy of the fourth ventricle and correlate this to the various pathologies. The aim of this review is to improve the ability of the readers to recognise the change in shape and configuration of the fourth ventricle, enabling early detection of pathologies.

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,...
