Secondary extracranial meningiomas extending into the paranasal sinuses
Abstract:
Meningiomas are well-recognized tumors of the central nervous system. Extracranial meningiomas, secondarily extended into the paranasal sinuses, are rare tumors, comprising approximately 2% of all meningiomas. Extracranial meningiomas of the paranasal sinuses may present a diagnostic and the rapeutic challenge. We present a retrospective review comprising three cases and discuss the clinical presentation, imaging findings,diagnostic evaluation, and treatment options. The localizations included the frontal sinus, the ethmoid sinus, the sphenoid sinus and even the maxillary sinus. Complete surgical resection was achieved in one patient; meanwhile deliberate subtotal tumor resection was performed in the other cases in order to avoid severe neurological damage with sufficient tumor control.

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,...
