Newborn X-Ray - Massive Pneumoperitoneum
This is a surgical emergency. The X-ray shows classic radiological signs of massive free intraperitoneal air (pneumoperitoneum) in a newborn.
Radiological Signs Present
| Sign | Finding |
|---|---|
| Football Sign | Large oval radiolucency outlining the entire abdominal cavity - the most prominent finding here, characteristic of massive pneumoperitoneum in a supine infant |
| Rigler's Sign (Double Wall Sign) | Both inner AND outer walls of bowel loops are outlined by gas - normally only the inner wall is visible |
| Falciform Ligament Sign | Vertical linear density in the right upper quadrant/midline - falciform ligament outlined by surrounding free air |
| Continuous Diaphragm Sign | Free air under both hemidiaphragms making the diaphragm appear as a continuous line across midline |
Additional Findings
- Bowel loops - centrally displaced and clumped, floating in free air
- Moderate bowel distension - generalized, but no classic double/triple bubble obstruction pattern
- NG/OG tube in situ
- Lungs - mild basal atelectasis/compression bilaterally from raised intra-abdominal pressure
- Skeletal survey - grossly normal for gestational age
Differential Diagnosis (Newborn Pneumoperitoneum)
- Necrotizing Enterocolitis (NEC) with perforation - most common cause in neonates
- Spontaneous Intestinal Perforation (SIP/FIP) - especially in premature neonates
- Spontaneous Gastric Perforation - less common
- Meconium Ileus with perforation - usually associated with peritoneal calcifications (not prominent here)
- Iatrogenic perforation - from vigorous resuscitation or tube placement
Immediate Management
- Urgent Pediatric Surgery consultation - exploratory laparotomy likely required
- Needle decompression (bedside peritoneal tap/paracentesis) if respiratory compromise from elevated diaphragms
- NPO, IV access, broad-spectrum antibiotics (covering gram-negatives and anaerobes)
- Blood cultures, CBC, CMP, coagulation panel
- Ensure ventilatory support as needed
This X-ray is a classic teaching case - the Football Sign here is particularly well-demonstrated, with the massive air collection giving the abdomen an oval, football-like radiolucency on the supine AP view.

Annotated Teaching X-Ray - Massive Pneumoperitoneum (Newborn)
The orange arrows drawn on this X-ray point to the bilateral domes of the diaphragm, specifically highlighting the free air (gas) collection directly beneath both hemidiaphragms - confirming pneumoperitoneum.
Signs Demonstrated (Annotated & Present)
| Sign | Description |
|---|---|
| Continuous Diaphragm Sign (arrows highlight this) | Free subdiaphragmatic air outlines the entire diaphragm as a continuous line - including the central portion, which is normally hidden behind the cardiac shadow |
| Football Sign | Massive oval radiolucency filling the entire abdomen - free air outlines the peritoneal cavity like a football |
| Rigler's Sign | Both inner and outer bowel wall visible - free peritoneal air outlines the serosal surface |
| Falciform Ligament Sign | Faint vertical linear density in the right upper quadrant/midline - falciform ligament outlined by free air |
Compared to the Previous X-Ray (Bo Aleena)
This appears to be the same case (or a very similar one) - likely the annotated/teaching version of the same X-ray. The arrows have been drawn to demonstrate:
- The right hemidiaphragm dome (right arrow)
- The left hemidiaphragm dome (left arrow)
- Emphasizing the free gas lifting both domes from below
Key Teaching Points
- The Continuous Diaphragm Sign is the most classic sign on a supine AP neonatal film - you can see the central diaphragmatic tendon because air has collected beneath it
- On an erect film in an older child/adult, free air would collect under the right hemidiaphragm as a crescent - but in supine neonates, the Football Sign predominates
- The amount of free air here is massive - suggesting a large perforation (NEC with perforation being #1 on the differential)
Immediate Action
Surgical emergency - Pediatric surgery must be called immediately. The annotated arrows indicate this is likely a teaching case being shared for PG education (as noted in the previous image: "For pg's to interpret").
Pls brief the xray systematically in a paragraph
Here is a systematic paragraph-style briefing of the X-ray (using the annotated image - Bo Aleena, newborn):
Systematic X-Ray Interpretation - Newborn Abdomen/Chest (AP Supine)
This is an AP supine radiograph of a newborn. The film is adequately exposed and includes the chest and abdomen. On systematic review - starting with the technical adequacy, the projection is supine AP with reasonable exposure. Moving to the thorax, the lung fields show mild bilateral basal compression but are otherwise clear, with no consolidation or pleural effusion; the cardiac silhouette is partially obscured but not grossly enlarged. The diaphragm cannot be assessed in its normal contour as both hemidiaphragms are elevated and their central portions are outlined as a continuous line by subdiaphragmatic free air - the Continuous Diaphragm Sign. Under the abdomen, the dominant finding is a massive radiolucency occupying the entire peritoneal cavity, producing the classic Football Sign of neonatal pneumoperitoneum; the bowel loops are displaced centrally and both inner and outer bowel walls are clearly visible (Rigler's Double Wall Sign); a faint vertical linear density in the right upper quadrant represents the Falciform Ligament Sign. The skeletal structures including the ribs, spine, clavicles, and pelvis appear grossly normal for gestational age. An orogastric/nasogastric tube is in situ. Impression: Massive pneumoperitoneum in a newborn - most likely secondary to gastrointestinal perforation (NEC with perforation, spontaneous intestinal perforation, or gastric perforation). This is a surgical emergency requiring immediate pediatric surgical consultation and urgent exploratory laparotomy.
