Radiographic findings of a well-differentiated sinonasal neuroendocrine neoplasm: Case report and review of the literature

July 21, 2015  |  Cui Ping Mao, PhD; Ming Zhang, MD; Chen Niu, PhD; Min Li, MD; Yuan Wang, MD

Abstract

Typical carcinoid is a rare tumor among other neuroendocrine neoplasms that occur in the nasal cavity. Only a few cases of typical carcinoids in the nasal cavity have been reported. We report a case of typical carcinoid of the nasal cavity in a 61-year-old man who had a history...

Palliative endoscopic surgery for sinonasal metastases: A case report and literature review

February 2, 2015  |  Jason M. Roberts, MD; Christopher Brook, MD; Steven Parnes, MD

Abstract

Cancer metastatic to the paranasal sinuses often presents with ophthalmologic and facial deformities, as well as sinonasal complaints. These diminutive tumors are difficult to effectively treat, often leading to poor quality of life. Although breast cancer is a common cancer...

Cutaneous malignant melanoma metastatic to the sphenoid sinus

December 19, 2014  |  Silviu Albu, MD; Opincariu Iulian, MD; Sorin Necula, MD

While metastases to the paranasal sinuses are unusual, metastases to the sphenoid sinus are exceedingly rare, especially metastases of a cutaneous melanoma to the mucosa. We report the case of a 38-year-old man who presented with a solitary sphenoid sinus metastasis that had spread from a...

A rare occurrence of a fungus ball in the sphenoethmoid recess

October 18, 2014  |  Jae-Hoon Lee, MD; Ha-Min Jeong, MD

A fungus ball usually appears as a calcification within the sinus, suggesting the presence of a foreign body.

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.
