Fibrous dysplasia (FD) is an uncommon benign bone disorder of unknown etiology in which normal medullary bone is replaced by fibrotic and osseous tissue. FD of paranasal sinuses is usually secondary to extension from adjacent bones. It is rarely limited to the sinuses, let alone limited to the sphenoid sinus. Furthermore, the relationship between h...

... and ibuprofen). She also complained of mild right nasal congestion and intermittent mild otalgia. Physical examination was normal apart from nasal septal deviation. Computed tomography (CT) of the paranasal sinuses showed expansion of the sphenoid bone demonstrating diffuse ground-glass matrix and sclerosis obliterating the sphenoid sinus cavity (Fig. 1). Magnetic resonance imaging (MRI) was highly suggestive of fibrous dysplasia of the sphenoid bone, which appeared as expanded mass with dark T2 signal and T1 hypointense signal (Figs 2 and 3). Near-total excisional biopsy was performed using endoscopic transeptal approach to sphenoid sinuses. Histopathological examination of several ...

Amyloidosis is the process of extracellular deposition of protein fibrils and manifests pathologically as a systemic or localized process. Localized amyloidosis of the head and neck is uncommon, and involvement of the sphenoid sinus is exceedingly rare. We describe a case of localized amyloidosis isolated from the sphenoid sinus. A descriptive lite...

We report a case of cemento-ossifying lesion involving the left ethmoid and sphenoid sinus in a 17-year-old male patient. Computed tomography showed an expansile hyperdense lesion with sclerosed peripheral man...
Isolated sphenoid sinus disease can be difficult to diagnose and treat due to the non-specificity of their symptoms and to the likelihood that these pathologies can present late with complications. For these reasons, significant delays in the diagnosis and treatment of the patient may happen. In addition, due to the proximity of the sphenoid sinus...
Introduction: Fungal sphenoiditis is a rare case in clinical practice. Usually affecting just one sinus, Aspergillus is
the most common cause of fungal sinusitis. Atypical headache with unresponsive to analgetics is one of symptom
from Isolated Sphenoid sinusitis.
