Non-otogenic lateral sinus thrombosis: A complication of acute sphenoid sinusitis

August 28, 2014  |  Jessica M. Somerville, MD; Erik Lyman, MD; Jerome W. Thompson, MD, MBA; Rosemary Stocks, MD, PharmD

Abstract

The consequences of intracranial spread of sinus infection can be dismal. The subtle presentation of sphenoid sinusitis often leads to a delay in diagnosis. The disease may go unrecognized until complications are severe enough to cause more localizing symptoms. Often infections...

Metastatic hepatocellular carcinoma presenting as a sphenoid sinus mass and meningeal carcinomatosis

June 9, 2014  |  Hilwati Hashim, MBBCh, MRad; Kartini Rahmat, MBBS, MRad; Yang Faridah Abdul Aziz, MBBS, MRad; Patricia Ann Chandran, MD, MPath

Abstract

We report the case of a 30-year-old woman who was referred to us for evaluation of a 2-week history of fever, headache, vomiting, bilateral ptosis, and blurred vision. Imaging obtained by the referring institution had identified a sphenoid sinus mass and diffuse meningeal...

Unusual presentations of choanal polyps: Report of 3 cases

February 12, 2014  |  Ali Ozdek, MD; Halil Erdem Ozel, MD

Abstract

Most choanal polyps arise from the maxillary sinus, and they are called antrochoanal polyps. Their typical endoscopic and radiologic appearance makes them easy to diagnose. However, some choanal polyps originate in unusual sites in the paranasal sinuses and nose, such as...

The significance of magnetic resonance imaging and computed tomography findings in sphenoid sinus agenesis

February 12, 2014  |  Lokman Uzun, MD; Omer Faik Sagun, MD; Bulent Seferoglu, MD; Omer Etlik, MD; and Kamran Mahmutyazicioglu, MD

Abstract

Agenesis of the sphenoid sinuses is a very rarely encountered anatomic variation. Findings on magnetic resonance imaging can mislead the radiologist and clinician. Therefore, the gold standard for diagnosis is computed tomography (CT) of the paranasal sinuses. We present the...

Endoscopic view of sphenoid sinus illumination and transillumination

February 12, 2014  |  Ken Yanagisawa, MD, FACS; Dewey A. Christmas, MD; Joseph P. Mirante, MD, FACS; and Eiji Yanagisawa, MD, FACS

The sphenoid sinus has been considered a more challenging sinus to view with the lighted guide wire; unlike the other three paranasal sinuses, the sphenoid sinus is “hidden” from view because of its more posterior location.

The endoscopic transnasal paraseptal approach to a sphenoid sinus osteoma: Case report and literature review

December 20, 2013  |  Frank Rikki Canevari, MD; Georgios Giourgos, MD; Andrea Pistochini, MD

Abstract

Osteomas are the most common benign tumors of the nose and paranasal sinuses. Their symptoms, which are nonspecific, occur as the result of a blocked nasal airflow or, in some rare cases, the involvement of nearby structures. Isolated sphenoid sinus osteomas are very rare, as...

Sphenoid sinus mucocele as a cause of isolated pupil-sparing oculomotor nerve palsy mimicking diabetic ophthalmoplegia

December 20, 2013  |  Alireza Mohebbi, MD; Hesam Jahandideh, MD; Ali Amini Harandi, MD

Abstract

A 37-year-old woman presented with isolated right-sided oculomotor nerve palsy. Neurologic examination revealed no other disorder. Computed tomography of the paranasal sinuses demonstrated complete opacification of the sphenoid sinus. Dense mucoid fluid was drained from the...

Endoscopic view of the sphenoid sinus seen through the posterior ethmoid sinus

October 24, 2013  |  Joseph P. Mirante, MD, FACS; Dewey A. Christmas, MD; Eiji Yanagisawa, MD, FACS

Care must be taken when entering the sphenoid sinus, to dissect inferiorly and medially to avoid injury to the vital structures of the lateral wall of the sphenoid sinus.

Progressive blindness caused by an unusual sphenoid sinus dehiscence

September 19, 2013  |  Mariana Marquez, MD; Enrique Palacios, MD, FACR; Jeremy Nguyen, MD; Harold R. Neitzschman, MD, FACR, FACNM, FAAP

The optic nerve and other important structures in the anterior skull base can be involved in chronic sphenoidal sinus disease.

Endoscopic view of the posterior septal branch of the sphenopalatine artery

April 18, 2013  |  Jae Hoon Lee, MD

Moderate posterior epistaxis can be avoided if the posterior septal branch of the sphenopalatine artery is accounted for when extending the natural ostium inferiorly to a distance greater than approximately 5 mm.

Sphenoethmoid sinusitis in a child resulting in a disastrous intracranial sequela

November 1, 2012  |  Aye Jane Sow, MS(ORL-HNS); Jeevanan Jahendran, MS(ORL-HNS); Charng Jeng Toh, MS(Neurosurg); Thean Yean Kew, FRCR

Abstract

Localized sphenoethmoid sinusitis in children is a rare occurrence. It is usually overlooked because of the misconception that the sinuses are not developed. We describe a case of localized acute sphenoid and right posterior ethmoid sinusitis that presented as right frontobasal...

Renal cell carcinoma metastatic to the sinonasal region: Three case reports with a review of the literature

November 1, 2012  |  Pradipta Kumar Parida, MS, DNB, MNAMS

Abstract

The paranasal sinuses are a rare location for metastases. The most frequent infraclavicular primary tumor to metastasize to the nose and paranasal sinuses is renal cell carcinoma. Three cases of bilateral renal cell carcinoma with metastases to the paranasal sinuses and with...
