We present 2 patients with giant cell reparative granuloma (GCRG) of the sphenoid bone. The first patient is an 8-year-old boy with involvement of the greater wing, and the second is a 53- year-old man with a lateral pterygoid plate mass. Both patients presented with rapid expansion of lytic bone lesions, which had solid and cystic components and lacked matrix calcification. Biopsies were indet...
Background: Although pituitary adenomas have been described in association with polyostotic fibrous dysplasia in McCune-Albright Syndrome, no such relationship has been described with monostotic fibrous dysplasia. The authors describe a case of monostotic fibrous dysplasia of the sphenoid bone and concomitant pituitary adenoma in a 25-year-old male. To the authors’ knowledge this is the first s...
OBJECTIVES To establish and compare the distance and angle from the limen nasi to the sphenoid ostium in pediatric patients with normal sinonasal anatomy vs pediatric patients with cystic fibrosis (CF). DESIGN Retrospective review of computed tomographic images. SETTING Tertiary university-based medical center. PARTICIPANTS Patients (newborn to age 20 years) with normal sinonasal anatomy ...
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...
Invasive fungal sinusitis of the paranasal sinuses in a healthy immunocompetent person is uncommon. Isolated involvement of any paranasal sinus, particularly sphenoid sinus is rare. In this study, five immunocompetent patients who had no nasal complaints but obscure symptoms of headache and orbital symptoms such as diplopia, retro-orbital pain and loss of vision were diagnosed to be having fulm...
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...
One type of congenital intrasphenoidal meningoencephalocele is remnant of lateral craniopharyngeal (Sternberg's) canal. We present a case of a 23-year girl with 10-month history of right side CSF rhinorrhea. CT scan, MRI revealed congenital meningoencephalocele and CSF leak from middle fossa to right side of sphenoid sinus, and there were bony defects at the floor of the anterio...
In a study of 156 skulls the interior of one particular skull showed many additional foramina on the sphenoid bone, one large foramen almost on the centre of sella turcica (0.64%) (the large craniopharyngeal canal); a second foramen on the inferomedial angle of the optic canal (the lateral craniopharyngeal canal), which were also present in 2 more skulls (2.56%); and two large foramina Vesalii ...
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...
