Orbital, sphenoidal ridge and spinal meningiomas occurring in one patient
Abstract:
From the more than 1500 intracranial meningiomas, 600 spinal meningiomas and 400 orbital tumours operated on in our clinic between 1935-1980 we are reporting the case of a patient with multiple meningiomas which gradually developed in three different regions - right orbital, the left sphenoidal ridge and the upper thoracic region. We have not found any comparable case with these features in the medical literature. From the clinical, radiological and scintigraphic findings we established the coexistence and the gradual development of these multiple meningiomas in three different regions. The correlation of the clinical and paraclinical findings offered us the presumptive diagnosis of multiple orbito-cranial and spinal meningiomas before the last two operations.

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,...
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...
