X Ray Sella

The best X‑ray view for visualizing the sella turcica is the lateral skull (lateral cephalometric) projection. It provides a true profile of the pituitary fossa, enabling assessment of contour, size, calcification, and bony erosion. For suspected pituitary lesions or detailed soft‑tissue evaluation, MRI is the imaging modality of choice due to superior contrast and resolution.

The normal sella (sella turcica) in adults is small: anteroposterior length commonly about 5–16 mm, depth (vertical) about 4–12 mm, and transverse width roughly 10–13 mm. The pituitary gland height within the sella is usually under about 6–7 mm in nonpregnant adults. Values vary by age and sex; radiology interprets enlargement in clinical context.

The sella (sella turcica) is a saddle-shaped depression in the sphenoid bone at the skull base that houses and protects the pituitary gland. It forms a bony cradle with a roof (the diaphragma sellae) separating the gland from the brain. Its size and shape are clinically important—abnormalities can indicate pituitary tumors, congenital variants, or other skull-base disorders.

The sella (short for sella turcica) is a saddle-shaped depression in the sphenoid bone at the skull base that houses and protects the pituitary gland. It serves as an anatomical landmark on imaging and in surgery. Changes in sella size or shape—such as enlargement, deformation, or “empty sella”—can signal pituitary tumors, fluid shifts, or other endocrine and structural conditions.

No. Empty sella is not a brain tumor. It’s an anatomic finding where cerebrospinal fluid fills the sella turcica, often flattening the pituitary gland. It’s usually incidental and benign, though it can sometimes cause headaches or hormonal imbalances. Causes include a congenital defect or prior pituitary injury/treatment. MRI and hormonal testing are recommended if symptoms occur.

Sella Pass (Passo Sella), about 2,240 m in the Dolomites, is famous for its dramatic Sella Group panoramas and year‑round outdoor activities. It links Val Gardena and Val di Fassa and is a hotspot for hiking, rock climbing and via ferrata, cycling and motorbiking, and winter skiing on the Sella Ronda circuit. Its winding roads and alpine views draw photographers and cyclists worldwide.
