Plasma cell neoplasms of the head and neck region can be extramedullary plasmacytoma of the bone, solitary plasmacytoma of the bone, and local manifestations of multiple myeloma. A 70-year-old male patient was admitted to our hospital with diplopia of four-day history. Magnetic resonance imaging showed soft tissue in the sphenoid sinus. Endoscopic biopsy was taken from the sphenoid sinus, which...

A 35-year-old female complained of right-sided watery nasal discharge persisting for 2 weeks. Neuroimaging investigations revealed a defect in the lateral side of middle cranial fossa, temporal lobe encephalocele protruding into the lateral extension of the sphenoid sinus, and cerebrospinal fluid (CSF) collection on the right side of the sphenoid sinus. The transcranial approach was performed f...

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...

Background: Injury to the cavernous portion of the Internal Carotid Artery (ICA) during nasal endoscopic sinus surgery is a rare complication, which is associated with high rates of morbidity and mortality. ICA is more vulnerable to iatrogenic injury inside the sphenoid lateral wall when it runs in a more medial course which although is uncommon but a normal variant and when the ICA runs only i...

Alongside the past development of endoscopic sinus surgery, knowledge about the anatomy of the sinuses has become crucial for surgeons. The sphenoid sinus is one of the most variable of all sinuses. Its relations to vital vascular and nervous elements make its approach a challenge for endoscopic surgeons. These relations include the internal carotid artery, the optic nerve, the pituitary gland,...

OBJECTIVES To assess the role of multidetector computed tomography (CT) and CT virtual sinoscopy in the evaluation of chronic sphenoid sinusitis and to compare the imaging findings with functional endoscopic sinus surgery. DESIGN Prospective study. SETTING Tertiary care teaching hospital. PATIENTS Thirty patients with chronic sphenoid sinusitis referred for preoperative CT. INTERVENTION...

Clinical reports of primary sphenoid sinus melanoma and isolated gastric metastatic melanoma are rare. Thus, to the best of our knowledge, the present study reports the first case of isolated gastric metastasis from a sphenoid sinus melanoma. The aim of the present study was to discuss the clinicopathological and radiographic characteristics, the treatment strategy and the prognosis of sphenoid...

Arrested pneumatization of the sphenoid sinus is a developmental variant that is not always well recognized and is often confused with other pathologies associated with the skull base. This report describes the case of a patient referred for cone-beam computed tomography (CBCT) imaging for dental implant therapy. CBCT demonstrated a well-defined incidental lesion in the left sphenoid sinus with...

Abstract Introduction: Arachnoid cysts are developmental cystic lesions which may be found as an incidental finding on neuroimaging or present with symptoms of headache, seizure and neurologic deficit. Presentation with seizure is more common with larger sizes and temporal location. Presentation with TLE is rare, and fenestration of cysts had variable results for seizure control. Here in, we r...

PURPOSE The purpose of this study was to report the case of a female patient who had a giant cell tumor in the paranasal sinus during childhood, and while undergoing multiple resection surgeries experienced optic atrophy in both eyes. CASE PRESENTATION This study involved a 35-year-old woman who was previously diagnosed with a giant cell tumor of the paranasal sinus bone at age 13. A CT scan ...
