Lateral Skull X-Ray — Interpretation
This is a lateral (side) view skull radiograph, showing the right or left profile of the head. Here is a structured breakdown of what is visible:
Structures Visible
| Region | What is seen |
|---|---|
| Calvarium (skull vault) | The large curved dome at the top — inner and outer tables of cortical bone with diploë (cancellous bone) between them |
| Frontal bone | The forehead area, upper left of the image |
| Parietal bone | The large flat bone forming most of the visible vault |
| Occipital bone | Posterior (back) part of the skull |
| Facial bones | Lower mid portion — nasal bones, maxilla visible |
| Mandible (jaw) | The lower jaw with teeth roots clearly visible at the bottom of the image |
| Teeth / dentition | Multiple teeth visible in the upper and lower jaws — roots and crowns apparent |
| Nasal region | The prominent protrusion in the mid-face area |
| Sella turcica region | The saddle-shaped depression at the skull base (sphenoid bone area) — appears as a brighter white oval structure centrally |
| Mastoid air cells | Honeycomb-like pattern behind the ear region |
Notable Observations
-
Sella turcica — appears as a well-defined bright (dense) ovoid structure. This is normal, but enlargement here can suggest a pituitary lesion.
-
Calvarium thickness — appears generally uniform, which is normal. Abnormal thickening or thinning would suggest systemic disease.
-
Teeth and jaw — Lower teeth and jaw (mandible) are clearly seen with normal-appearing dentition.
-
No obvious fracture lines visible in this view, though the image is partially cropped and taken at an angle (photo of a film on a light box), which limits a complete read.
-
Vascular markings — faint linear dark lines (middle meningeal artery grooves) may be present within the vault, which is normal.
Limitations of This Image
- The photo is taken at an angle with a camera, causing glare and perspective distortion.
- The image is cropped — the posterior skull and top of the vault are cut off.
- No clinical history or comparison is available, so specific pathology cannot be definitively confirmed or excluded.
Important: This is an educational interpretation only. A qualified radiologist must formally report any clinical X-ray. If this film belongs to a patient, please consult the treating physician.

Looking at this lateral skull X-ray more carefully for any abnormal findings:
Summary of Findings
⚠️ Key Abnormality — Mandibular/Jaw Region
The lower jaw (mandible) shows a notable dark (radiolucent) area near the tooth-bearing region. This could represent:
- A dental abscess or periapical infection
- A dentigerous cyst (fluid-filled sac around a tooth)
- A jaw cyst or benign tumor (e.g., ameloblastoma)
Teeth
There appears to be missing or impacted teeth with possible bone loss around the roots — suggesting chronic dental/periodontal disease.
Skull Vault
- No obvious fracture lines
- Bone density appears within normal range
- No gross lytic lesions or areas of bone destruction in the calvarium
Sella Turcica
Appears of normal size — no obvious enlargement to suggest a pituitary mass.
In Short:
The most striking finding is in the jaw/dental region — there is a dark lucent area near the lower teeth, most likely representing a dental cyst, abscess, or bone loss from dental disease. No acute skull fracture or gross intracranial bony pathology is apparent.
