Abstract:
There have only been 18 cases reported in the literature of an epidermoid tumor arising in the interhemispheric fissure. We report a 45-year-old woman with an epidermoid tumor arising in the interhemispheric fissure. She presented with a focal convulsive seizure. Radiological imaging identified a tumor in the interhemispheric fissure, which was subtotally removed due to adherence to both anterior cerebral arteries and the cerebral cortex. Epidermoid tumor was confirmed by histopathology. Epidermoid tumors rarely arise in the interhemispheric fissure, but are often adherent to surrounding structures and thus, as in the presented case, complete resection may be unwise.

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,...
