The orbitofrontal fibrous dysplasia is a rare, non-malignant disease that involves the development and thickening of craniofacial bones, causing facial asymmetry, visual, neurological and dental complications. Decreased visual acuity in orbitofrontal and sphenoidal fibrous dysplasia appears as a result of compressive lesions on the optic nerve. The aim of this article is to present the ophthalm...

Defects in the lateral wall of the sphenoid sinus are a rare cause of cerebrospinal fluid (CSF) rhinorrhea. The etiology of these defects may be congenital or acquired. A dehiscent lateral craniopharyngeal canal, or Sternberg canal, arises from a malunion of two parts of the developing sphenoid bone: the greater wing and the basisphenoid.1,2 Originally reported in 4% of healthy adults,3 its tru...

Spindle cell carcinoma (SpCC) is a rare variant of squamous cell carcinoma (SCC). SpCC of sinonasal origin is relatively rare and more aggressive than normal SCC. It most commonly involves the maxillary sinus, and rarely the sphenoid sinus. The present study reports a case of sphenoid sinus SpCC presenting with bilateral visual loss. Following endoscopic sinus decompression surgery, the patient...

We present a patient with isolated intracranial mucormycosis that remained indolent for several months. The mucormycosis formed a mass in the prepontine cistern, probably spreading from the sphenoid sinus. We propose that at least some cases of what is considered isolated CNS mucormycosis develop from such unrecognized indolent infections. Mucormycosis may present as a mass in the basilar ciste...
