AN UNUSUAL PRESENTATION OF HUGE MENINGIOMA EXTRUDING OUT OF SKULL
Abstract:
Scalp masses are commonly seen in clinical practice. They range from simple sebaceous cyst to malignant neoplasms. Clinical presentation is straight forward in most of the cases. Simple subcutaneous swelling till erosion of scalp and skull all can occur. However very few intracranial masses present with exophytic scalp swelling. This is because they have to erode dura, thick skull bone and all the layers of scalp to appear out on scalp. It is very unusual that an intracranial mass present like a scalp swelling. Some of the intracranial masses have tendency to erode skull. Dermoid & meningioma are among the most common.

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...
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...
