The interest and difficulty of sphenoid tumor imaging relate mainly to its great diversity. Detection may be difficult due to variable tumor size and often misleading clinical data. Because the sphenoid is located at the center of the skull base, tumor extension may be quite variable and difficult to assess, requiring sufficient knowledge of anatomy and imaging features to detect tumor spread, especially retrograde perineural spread, since this has a negative impact on prognosis.

Pituitary neuroendocrine tumors (PitNETS) are common intracranial tumors, but extrasellar or ectopic PitNETS are very rare and supposed to originate from some pituitary remnants. They are mostly found in sphenoidal sinus. But particularly, ectopic clival PitNETS are highly aggressive and can cause bone invasion and can be misdiagnosed as other lesions of the skull base such as chordomas.

The falx cerebri (FC) corresponds to the invagination of the meningeal dural layer into the longitudinal fissure between the two cerebral hemispheres. Infrequently, the FC ossifies, forming an extra bone deposition, giving the impression of "supernumerary" bone. The present study aimed to investigate the presence of FC ossification in a large sample of the Greek population.

Fibrous dysplasia, a rare benign condition with an uncertain cause, is characterized by substituting normal medullary bone with abnormal and weak fibrous and osseous tissue. This primary bone disorder is non-neoplastic and involves a deficiency in osteoblastic differentiation and maturation, which begins in the bone's mesenchymal precursor. A 20-year-old female attended ENT OPD with complaints of headache for 3 years, A diagnostic nasal endoscopy was done which showed no significant abnormalities, and CT PNS was done which showed Extensive sclerotic bony expansion with a ground glass appearance involving the clivus, right greater wing of sphenoid, pterygoid processes - Likely fibrous dysplasia since she had no other signs or symptoms, she was kept under observation.

Chronic rhinosinusitis is a prevalent condition characterized by inflammation of the nasal and paranasal sinus cavities, significantly impacting quality of life and healthcare utilization. Computed tomography imaging is vital in assessing anatomical variations that may contribute to chronic rhinosinusitis pathogenesis. This study aimed to identify anatomical variations in the nasal cavities and paranasal sinuses using CT imaging and explore their relationship with sinus mucosal abnormalities.
