Sphenoid sinus lesions can present with a multitude of symptoms/signs including ophthalmic disturbances. We describe a total of five patients, of which two had mucoceles and rest three had fungal infection. Ophthalmic symptoms/signs were the ones we were really interested in. We also present one case which had isolated sphenoid fungal sinus. We also give details of their presentation, investiga...

OBJECTIVE We report a unique case of anatomical variation of the extracranial course of the optic nerve running in the floor of the sphenoid sinus. METHOD Clinical and radiological findings are presented. RESULTS A 39-year-old woman with Turner syndrome presented with severe headache associated with visual disturbances. Magnetic resonance imaging revealed a mass presumed to be a sella menin...

Miller Fisher syndrome (MFS), a variant of Guillain-Barré syndrome, is a rare disorder typically characterized by a triad of ataxia, areflexia, and ophthalmoplegia, which may have a highly variable clinical presentation. We report a case of MFS in a 45-year-old female presenting with sphenoid sinusitis and sixth nerve palsy. She underwent endoscopic sphenoid sinusotomy without improvement, had ...

Sphenoid sinus mucocele is an uncommon lesion related to inflammatory disease that is diagnosed after surgery or a traumatic event. This report describes an unusual case revealed by bacterial meningitis and cerebral abscess in a 12-year-old child. CT and MR imaging allowed precise extension to the skull base in preoperative management and follow-up investigations. Endoscopic transnasal marsupia...

Spheno-orbital meningioma have traditionally been defined as secondary tumors of the orbit originating from the dura of the sphenoid wing bone. Nevertheless, pathologic findings reveal a distinct periorbital component as a defining feature of these lesions. These tumors are characterized by an intraosseous mass growth leading to a significant hyperostosis involving the sphenoid wing, the orbita...

Traumatic pseudoaneurysms of middle meningeal artery (MMA) and medial sphenoid wing dural arteriovenous fistula (dAVF) are rare. These lesions usually result from traumatic brain injury, and associated with skull fracture. In this paper, the authors report a case of a patient with a ruptured traumatic pseudoaneurysm of MMA and medial sphenoid wing dAVF presented with an intracerebral hemorrhage...

Intracranial "kissing" carotid arteries are a rare variant of the carotid arteries, where both internal carotid arteries deviate medially and touch each other near the midline within the sphenoid sinus or the sphenoid bone, including the sella. This anomaly is particularly important since it may cause or mimic pituitary disease and also may complicate transsphenoidal surgery. We report a rare c...

ABSTRACT The Sphenoid Sinus is considered the paranasal sinus with more variation to degree of pneumatization. Thus, this work aimed report first case on interference anatomical for orthognathic surgery. A 18- year-old woman, isolated cleft palate repaired, was submitted surgery correct maxillomandibular skeletal discrepancy. cone beam computed tomography (CBCT) exam performed preoperative plan...

A 61-year-old Japanese woman presented with a headache and appetite loss lasting for nine days and was admitted to our hospital, where she was diagnosed with pneumococcal meningitis associated with acute sphenoid sinusitis. While the administration of meropenem and dexamethasone ameliorated the meningitis, right third and sixth nerve palsy suddenly developed 10 days after admission. CT angiogra...

A benign pleomorphic adenoma is the most common tumor of the salivary glands. This tumor has the potential to metastasize to bone, the head and neck region, visceral organs and skin. Although there a few reports about a benign pleomorphic adenoma metastasizing to the maxillary sinus in the paranasal sinuses, there are no reports about a metastatic benign pleomorphic adenoma in the sphenoid sinu...
