Abstract:
A 14-year-old girl presented with symptoms and signs of left otomastoiditis and meningitis. CT and MRI revealed a largely expanded cavum septum pellucidum with enhancing walls and findings suggesting left otomastoiditis and meningitis. At surgery, an abscess was found within the cavum septum pellucidum. Five similar cases have been reported in the literature. To our knowledge, this is the first case associated with otomastoiditis. Although rare, abscess of the cavum septum pellucidum should be suspected in patients with meningitis and/or head trauma and delayed clinical deterioration.

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,...
